It can be seen from Table 6.1.24.1.2.1-1 that the 2nd harmonics of BS transmitting in Band 12 may fall into the BS receive band of Band 21, while the 3rd IMD products caused by BS supporting CA of Band 4 and Band 12 may fall into the BS receive band of Bands 12, 13, 14, 17, 22, 28, 42, 43 and 44. Note that the calculation in Table 6.1.24.1.2.1-1 (except the last row) assumes the BS is transmitting with the whole 45 MHz DL frequency of Band 4 and the whole 17 MHz DL frequency of Band 12. If the BS is only transmitting an up to 20 MHz DL in Band 4 and an up to 10 MHz DL in Band 1 as stated in the WIDS, then the 3rd IMD products may only fall into the BS receive band of the Bands 12, 17, 22, 28, 42, 43 and 44 as shown in the last row in Table 6.1.24.1.2.1-1, and the 3rd IMD products will not fall into the BS own (up to 10 MHz) receive block within Band 12, and may only fall into the BS receive band of certain frequency range within Band 12 and Band 17 under the transmit configurations shown in Table 6.1.24.1.2.1-2 below.

It should be noted that Bands 21, 28 and 44 are not intended for use in the same geographical area as Bands 4 and 12. Therefore, the focus here will be on the IMD falling into Bands 12, 17, 22, 42 and 43.
With the performances of the current BS antenna system, transmit and receive path components, amplifiers, pre-distortion algorithms and filters, it is expected that the IMD interference generated within the Band 22, 42 or 43 receiver would be well below the receiver noise floor eliminating the possibility of receiver desensitization, provided that Bands 4 and 12 BS transmitters do not share the same antenna with Band 22, 42 or 43 BS receiver.
On the other hand, it is recommended that Bands 4 and 12 BS transmitters should not share the same antenna with Band 22, 42 or 43 BS receiver, or Band 12 or 17 BS receiver for the affected frequency ranges if the aforementioned BS transmit configurations are used, in order to prevent BS receiver desensitization, unless the antenna path meets very stringent 3rd order PIM specification so that the PIM will not cause Band 12, 17, 22, 42 or 43BS receiver desensitization. |

It can be seen from Table 6.1.25.1.2.1-1 that the 2nd harmonics of BS transmitting in Band 12 may fall into the BS receive band of Band 21, while the 2nd IMD products caused by BS supporting CA of Band 7 and Band 12 may fall into the BS receive band of Bands 1, 2, 22, 25, 33, 35, 36, 37, 39 and 42. In addition to this, 3rd order IMD products may fall in Bands 12, 13, 14, 17, 18, 26, 27, 28, 38, 41 and 44. Note that the calculation in Table 6.1.25.1.2.1-1 (except the last row) assumes the BS is transmitting with the whole 70 MHz DL frequency of Band 7 and the whole 17 MHz DL frequency of Band 12. If the BS is only transmitting up to 20 MHz DL in Band 7 and an up to 10 MHz DL in Band 12 as stated in the WIDS, then the 3rd IMD products may only fall into the BS receive band of the Bands 12, 17, 28, 38, 41 and 44 as shown in the last row in Table 6.1.25.1.2.1-1, and the 3rd IMD products will not fall into the BS own (up to 10 MHz) receive block within Band 12, and may only fall into the BS receive band of certain frequency range within Band 12 under the transmit configurations shown in Table 6.1.25.1.2.1-2 below.

It should be noted that Bands 1, 28 and 44 are not intended for use in the same geographical area as Bands 7 and 12. Also, bands 33, 35, 36, 37, 38 and 39 are not intended for use in the same geographical area as band 7 and 12. Therefore, the focus here will be on the IMD falling into Bands 2, 12, 17, 22 and 42.
With the performances of the current BS antenna system, transmit and receive path components, amplifiers, pre-distortion algorithms and filters, it is expected that the IMD interference generated within the Band 22 or 42 receiver would be well below the receiver noise floor eliminating the possibility of receiver desensitization, provided that Bands 7 and 12 BS transmitters do not share the same antenna with Band 22 or 42 BS receiver.
In addition to this, it is recommended that Bands 7 and 12 BS transmitters should not share the same antenna with Band 26 BS receiver, or Band 12 BS receiver for the affected frequency ranges if the aforementioned BS transmit configurations are used, in order to prevent BS receiver desensitization, unless the antenna path meets very stringent 3rd order PIM specification so that the PIM will not cause Band 12, 17, 22 or 42 BS receiver desensitization.

It can be seen from table 6.2.1.1.2-1 that that the 3rd harmonics of BS transmitting in Bands 28 may fall into the BS receive band of Bands 30 and 40, while the 3rd IMD products supporting CA of Band 1 and Band 28 may fall into the BS receive band of Bands 5, 6, 12, 13, 14, 17, 18, 19, 20, 22, 26, 27, 28, 42, 43 and 44. Note that the calculation in table 6.2.1.1.2-1 (except the last row) assumes the BS is transmitting with the whole 60 MHz DL frequency of Band 1 and the whole 45 MHz DL frequency of Band 28. If the BS is only transmitting an up to 20 MHz DL in Band 1 and an up to 20 MHz DL in Band 28 as stated in the WIDS, then the 3rd IMD products may only fall into the BS receive band of the Bands 13, 14, 18, 22, 26, 27, 28, 42, 43 and 44 as shown in the last row in table 6.2.1.1.2-1. Moreover, the 3rd IMD products may only fall into the BS receive band of certain frequency range within Bands 18, 26, 27 and 28 under the transmit configurations shown, respectively, in tables 6.2.1.1.2-2, 6.2.1.1.2-3, 6.2.1.1.2-4 and 6.2.1.1.2-5 below. Note that the available frequency range for mobile cellular communications in Japan is 718 – 748 MHz for UL and 773 – 803 MHz for DL.

It should be noted that Bands 13, 14, 30, 40 and 43 are not intended for use in the same geographical area as Bands 1 and 28. Moreover, co-location of Band (1 + 28) transmitter and Band 44 transceiver implies FDD/TDD co-location on adjacent frequencies which requires the use of certain site-engineering solutions to avoid mutual interference. Therefore, the focus here will be on the IMD falling into Bands 18, 22, 26, 27, 28 and 42.
With the performances of the current BS antenna system, transmit and receive path components, amplifiers, pre-distortion algorithms and filters, we expect the IMD interference generated within the Band 22 or 42 receiver would be well below the receiver noise floor eliminating the possibility of receiver desensitization, provided that Bands 1 and 28 BS transmitters do not share the same antenna with Band 22 or 42 BS receiver.
On the other hand, it is recommended that Bands 1 and 28 BS transmitters should not share the same antenna with Band 22 or 42 BS receiver, or Band 18, 26, 27 or 28 BS receiver for the affected frequency ranges if the aforementioned BS transmit configurations are used, in order to prevent BS receiver desensitization, unless the antenna path meets very stringent 3rd order PIM specification so that the PIM will not cause Band 18, 22, 26, 27, 28 or 42 BS receiver desensitization.

Considering bands in the same geographical area we observe that the BS distortion could fall into the BS receive bands of band 3. With the performances of the current BS antenna system, transmit and receive path components, amplifiers, pre-distortion algorithms and filters the IMDs generated within the band 3 receiver should be well below the receiver noise floor eliminating the possibility of receiver desensitization.

For the 3-tone IMD analysis the maximum transmission as defined in table 6.3.2.1.1-1 is considered. None of the harmonics of one band fall into the receive band of the other. The intermodulation products generated by two operating bands do not impact the own receiver since TDD BS cannot transmit and receive simultaneously in a single band.
We have listed all the possible interference to other operating bands in table 6.3.2.1.2-2. It can be seen in the table that 2nd order harmonics may fall into BS receive band of band 43, two-tone 2nd order IMD products may fall into BS receive band of band 12, 13, 14,17, 27, 28, 44, two-tone 3rd order IMD products may fall into BS receive band of band 22 and band 42, and three-tone 3rd order IMD products caused by BS supporting carrier aggregation of band 39 and band 41 may fall into the BS receive band of band 1, 2, 7, 25, 33, 35, 36, 37, 38.
Currently Bands 1, 42 and 44 are used in the same geographical area as Bands 39 and 41. With the performances of the current BS antenna system, transmit and receive path components, amplifiers, pre-distortion algorithms and filters, it is expected that the IMD interference generated within the Band 1, 42 or 44 receiver would be well below the receiver noise floor, in order to avoid the possibility of receiver desensitization. Thus it is recommended that Bands 39 and 41 BS transmitters do not share the same antenna with Band 1, 42 or 44 BS receivers, unless the antenna path meets more stringent 2nd and 3rd order PIM specification so that the PIM will not cause Band 1, 42 or 44 BS receivers desensitization. Note that antenna sharing may be allowed as the state-of-the-art continues to evolve in the future.

For the UE, the distortion of band 39 could fall into the UE receive bands for band 43. As currently there is no deployment for band 39&41 and band 43 in the same geographical area, and a UE does not operate simultaneously in B39 + B41 and band 43, this should be not a problem in case the UE supports this band.

simultaneousRx-Tx
Indicates whether the UE supports simultaneous reception and transmission on different bands for each band combination listed in supportedBandCombination. This field is only applicable for inter-band TDD carrier aggregation.
According to this capability, two kinds of UEs can be considered for inter-band TDD carrier aggregation, i.e. the UE supporting simultaneous reception and transmission on different bands and the UE not supporting simultaneous reception and transmission on different bands. Accordingly, different UE reference architecture may be considered for UE requirement development depending on the need.
The focus of current TDD inter-band CA is 2DL+1UL not supporting simultaneous Tx/Rx. In this regard, the following reference UE architecture will be used as baseline for UE requirement development. The benefits of this architecture is that there would be no relaxation necessary for maximum output power which is critical for operation uplink coverage.

It can be seen from Table 6.3.3.1.2.1-1 that the 2nd harmonics of BS transmitting in Band 8 may fall into the BS receive band of Bands 2, 25, 33, 35,37 and 39 and none of 3rd harmonics may fall into the any E-UTRA operating BS receive band. In addition 2nd harmonics of BS transmitting in Band 27 may fall into the BS receive band of Bands 3, 4 , 10 and 3rd harmonics may fall into BS receive band of Bands 7, 38 and 41.
Meanwhile the 2nd IMD products caused by BS supporting carrier aggregation of Band 8 and Band 27 may fall into the BS receive band of Band 3, 9 and 3rd IMD products may fall into the BS receive band of Band 5, 6, 8, 13, 14, 18, 19, 20, 26, 27, 28, 41 and 44. Note that the calculation in Table 6.3.3.1.2.1-1 (except the last row) assumes the BS is transmitting with the whole 35 MHz DL frequency of Band 8 and the whole 17 MHz DL frequency of Band 27.
If the BS is only transmitting an up to 10 MHz DL in Band 8 and 10 MHz in Band 27 as stated in the WIDs, the 3rd IMD products will not fall into the BS receive band of the Band 6, 8, or 18
It should be noted that Bands 2, 4, 10, 13, 14, 18, 19, 20, 25, 33, 35, 37, 38 and 39 are not intended for use in the same geographical area as Bands 8 and 27. Therefore, the focus here will be on the harmonics and IMD falling into Bands 3, 5, 7, 9, 26, 27, 28, 41 and 44. With the performances of the current BS antenna system, transmit and receive path components, amplifiers, pre-distortion algorithms and filters, it is expected that the IMD interference generated within the Band 3, 5, 7, 8, 9, 26, 27, 28, 41 or 44 receiver would be well below the receiver noise floor eliminating the possibility of receiver desensitization, provided that Bands 8 and 27 BS transmitters do not share the same antenna with Band 3, 5, 7, 8, 9, 26, 27, 28, 41 or 44 BS receiver.

It shows that the second harmonics may fall into BS receive band of Band 43, and no third harmonics will fall into any BS receive band specified by 3GPP. In addition, no second order intermodulation products will fall into any BS receive band. The third order intermodulation products may fall into the BS receive band of Band 2, 7, 11, 21, 24, 25, 35, 39, 40 and 41.
Note that Band 2, 25 and 35 are not intended for use in the same geographical area as Band 1 and Band 3. It is suggested BS transmitters supporting CA of Band 1 and Band 3 should not share the same antenna with Band 7, 11, 21, 24, 39, 40, 41 and 43 BS receiver, unless the antenna path meets very stringent third order PIM specification so that the PIM will not cause Band 7, 11, 21, 24, 39, 40, 41 and 43 BS receiver desensitization. Specific analysis on the harmonics and IMD products with consideration on the adopted bandwidth and the carrier places are needed if considering the shared antenna.

As it can be seen from table 6.3.5.1.2-1, the 2nd order harmonics from BS transmitting in Band 8 may fall in the BS receive band of Bands 2, 25, 33, 35, 37, 39. Additionally 2nd order IMD products may fall into the BS receive band of Bands 3, 4, 9, 10, 24, 42 and 43. While 3rd order IMD products may fall into the BS receive band of Bands 5, 6, 12, 13, 14, 17, 18, 19, 20, 26, 27, 28, 38, 41 and 44.
Note that the calculation in table 6.3.5.1.2-1 (except the last row) assumes the BS is transmitting with the whole 70 MHz DL frequency of Band 7 and the whole 35 MHz DL frequency of Band 8. If the BS is only transmitting up to 20 MHz DL in Band 7 and up to 10 MHz DL in Band 8 as stated in the WID, then the 3rd IMD products may only fall into the BS receive band of certain frequency range within Bands 8, 38 and 41.
The transmit configurations of the BS transmitting in Bands 7+8 with 3rd IMD products into Band 8 receive band are:

As it can be seen from table 6.3.5.1.2-2 when Band 7 uses 15/20MHz there may be IMD products falling into Band 8 receive band. In such cases, it could be necessary to avoid sharing the same RF path for both transmitter and receiver side, or avoid such configurations in the BS.
In table 6.3.5.1.2-3 the harmonic interference study is provided from UL perspective for Band 7 and 8. It can be seen that the harmonic frequencies fall in the UL and DL bands of Band 3. This scenario is already covered by current specifications and hence no further relaxation is required for that. It can also be seen that 3rd harmonic interference from UL Band 8 falls into Band 7 receiver band in a general case. However it is under discussion if current spectrum holdings can be taken into account, and be verified if there is no harmonic impact.

389f9b67c003a620147a83200e3331ae | 36.851 | 6.3.5.1.4 MSD | A part of the uplink of Band 8, specifically 880-897MHz (only first 17MHz) may create third order harmonics into part of Band 7 downlink, specifically 2640-2690MHz (only last 50MHz).
The specification of this band into 36.101 will consider the additional insertion losses of a low-high combination plus the additional trap filter to attenuate the harmonic distortion. Additionally for those frequencies that can create harmonic interference an exception to reference sensitivity (as derived through MSD) is created.
The uplink configuration is limited in such a way that the 3rd harmonic overlap is maximized on the SCC in the high band. However, at the same time, the uplink configuration should respect the limitations needed for reference sensitivity on the PCC since both PCC and SCC are tested simultaneously. In the case of Band 8, the uplink configuration is limited to 25 RB in Table 7.3.1-2 of 36.101. Thus, the upper limit for MSD testing should also be limited to 25 RB so that the conditions for reference sensitivity on the PCC can be maintained.

It can be seen from Table 6.3.6.1.2.1-1 that the 2nd and 3rd harmonics as well as the 2nd IMD products of BS transmitting in Bands 2 and 30 will not fall into the BS receive band of any frequency band currently defined in 3GPP, but the 3rd IMD products supporting CA of Band 2 and Band 30 may fall into the BS receive band of Bands 1, 24, 30, 36, 37 and 40. Note that the calculation in Table 6.3.6.1.2.1-1 (except the last row) assumes the BS is transmitting with the whole 60 MHz DL frequency of Band 2 and the whole 10 MHz DL frequency of Band 30. If the BS is only transmitting an up to 20 MHz DL in Band 2 and an up to 10 MHz DL in Band 30 as stated in the WIDS, then the 3rd IMD products may only fall into the BS receive band of Bands 1, 24, 36, 37 and 40 as shown in the last row in Table 6.3.6.1.2.1-1.
It should be noted that Bands 1 and 40 are not intended for use in the same geographical area as Bands 2 and 30. Moreover, co-location of Band (2 + 30) transmitter and Band 36 or 37 transceiver implies FDD/TDD co-location on adjacent frequencies which requires the use of certain site-engineering solutions to avoid mutual interference. Therefore, the focus here will be on the harmonics and IMD falling into Band 24.
With the performances of the current BS antenna system, transmit and receive path components, amplifiers, pre-distortion algorithms and filters, it is expected that the IMD interference generated within the Band 24 receiver would be well below the receiver noise floor eliminating the possibility of receiver desensitization, provided that Bands 2 and 30 BS transmitters do not share the same antenna with Band 24 BS receiver.
Therefore, it is recommended that Bands 2 and 30 BS transmitters should not share the same antenna with Band 24 BS receiver to prevent BS receiver desensitization, unless the antenna path meets very stringent 3rd order PIM specification so that the PIM will not cause Band 24 BS receiver desensitization.
6.3.6.1.3 ΔTIB,c and ΔRIB (1 UL)
The transmitter and receiver requirements for CA_2A-30A are based on a front-end reference architecture supporting multiplexing of Band 2, Band 4 and Band 30 (“hexplexer”) that in turn enables support of the band combinations Band 2 + Band 4, Band 2 + Band 30 and Band 4 + Band 30 in the same device. More details can be found in Clause 6.3.2 of [8].
For the UE which supports CA_2A-30A the ΔTIB,c is defined for applicable bands in Table 6.3.6.1.3-1 (see Table 6.3.2.2.1-1 in [8]).

It can be seen from Table 6.3.7.1.2.1-1 that the 2nd and 3rd harmonics as well as the 2nd IMD products of BS transmitting in Bands 4 and 30 will not fall into the BS receive band of any frequency band currently defined in 3GPP, but the 3rd IMD products supporting CA of Band 4 and Band 30 may fall into the BS receive band of Bands 1, 2, 7, 25, 30, 33, 35, 36, 37, 38, 39, 40 and 41. Note that the calculation in Table 6.3.7.1.2.1-1 (except the last row) assumes the BS is transmitting with the whole 45 MHz DL frequency of Band 4 and the whole 10 MHz DL frequency of Band 30. If the BS is only transmitting an up to 20 MHz DL in Band 4 and an up to 10 MHz DL in Band 30 as stated in the WIDS, then the 3rd IMD products may only fall into the BS receive band of Bands 1, 2, 7, 25, 33, 35, 36, 37, 38, 39, 40 and 41 as shown in the last row in Table 6.3.7.1.2.1-1.
It should be noted that Bands 1, 7, 33, 38, 39 and 40 are not intended for use in the same geographical area as Bands 4 and 30. Therefore, the focus here will be on the harmonics and IMD falling into Bands 2, 25, 35, 36, 37 and 41.

6.3.7.1.3 ΔTIB,c and ΔRIB (1 UL)
Just as for CA_2A-30A (Clause 6.3.6.1.3), the transmitter and receiver requirements for CA_4A-30A are based on a front-end reference architecture supporting multiplexing of Band 2, Band 4 and Band 30 (“hexplexer”) that in turn enables support of the band combinations Band 2 + Band 4, Band 2 + Band 30 and Band 4 + Band 30 in the same device.

None of the harmonics of one band fall into the receive band of the other. The intermodulation products generated by two operating bands do not impact the own receiver since TDD BS cannot transmit and receive simultaneously in a single band.
IMD products of Bands 41 and 42 could fall into RX frequency range of some operating bands. However, it could be hard for those low bands less than 1GHz to share the same antenna with Band 41 and Band 42. IMD products could fall into Bands 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 17, 18, 19, 20, 21, 22, 24, 25, 26, 27, 28, 33, 35, 36, 37, 38, 39, 43 and 44, while Bands 1, 3, 5, 8, 9, 11, 18, 19, 21, 27, 28, 39, 43 or 44 could be used in the same geographical area (Region 3) as Bands 41 and 42. With the performances of the current BS antenna system, transmit and receive path components, amplifiers, pre-distortion algorithms and filters, it is expected that the IMD interference generated within the Band 1, 3, 5, 8, 9, 11, 18, 19, 21, 27, 28, 39, 43 or 44 receiver would be well below the receiver noise floor, in order to avoid the possibility of receiver desensitization. Thus it is recommended that Bands 41 and 42 BS transmitters do not share the same antenna with Band 1, 3, 5, 8, 9, 11, 18, 19, 21, 27, 28, 39, 43 or 44 BS receivers, unless the antenna path meets more stringent 3rd order PIM specification so that the PIM will not cause Band 1, 3, 5, 8, 9, 11, 18, 19, 21, 27, 28, 39, 43 or 44 BS receivers desensitization. Note that antenna sharing may be allowed as the state-of-the-art continues to evolve in the future.

It also can be seen that 2nd order intermodulation products may fall into BS receive band of Band 24. 3rd intermodulation products may fall to UL frequencies of Bands 7, 8, 20, 28, 40, 41 and 44.
It should be noted that Band 5 and Band 13 are not meant to be deployed together in the same geographic area as Bands 3, 8, 9, 20, 28, 38, 40 and 44. Therefore the focus here will be on the harmonics of Band 5 falling into Bands 4, 10 and 41, and IMD products falling into Band 7, 24 and 41.
It is recommended that Band 5 and Band 13 BS transmitters not share an antenna with Band 4, 7, 10, 24 or 41 BS receivers. However Band 4, 7, 10, 24 and 41 would use separate antennas from Band 5 and Band 13, due to that high/low bands use separate antennas at BS side. There is no need to address above issue in inter-band carrier aggregation context.

It can be seen from Table 6.3.10.1.2.1-1 that the 2nd harmonics of BS transmitting in Band 18 may fall into the BS receive band of Bands 3, 4, 9 and 10, and the 3rd harmonics of BS transmitting in Band 18 and restricted Band 28 may fall into the BS receive band of Bands 30, 38, 40 and 41, while the 2nd IMD products caused by BS supporting CA of Band 18 and restricted Band 28 may fall into the BS receive band of Band 24, and the 3rd IMD products may fall into the BS receive band of Bands 5, 6, 7, 8, 12, 13, 14, 17, 19, 20, 26, 28, 40, 41 and 44. Note that the calculation in Table 6.3.10.1.2.1-1 (except the last row) assumes the BS is transmitting with the whole 15 MHz DL frequency of Band 18 and the whole 30 MHz DL frequency of restricted Band 28. If the BS is only transmitting an up to 15 MHz DL in Band 18 and an up to 10 MHz DL in restricted Band 28 as stated in the WIDS, then the 3rd IMD products may only fall into the BS receive band of the Bands 7, 8, 12, 13, 14, 17, 20, 28, 40, 41 and 44 as shown in the last row in Table 6.3.10.1.2.1-1. Note that the 3rd IMD products will not fall into the BS receive frequency range within restricted Band 28, or the BS receive frequency range within Band 8 (900 – 915 MHz) that is allocated in Japan. Also the 3rd IMD products may only fall into the BS receive band of certain frequency range within Band 28 under the transmit configurations shown in Table 6.3.10.1.2.1-2 below.

It should be noted that Bands 4, 7, 10, 12, 13, 14, 17, 20, 24, 30, 38, 40 and 44 are not intended for use in the same geographical area as Bands 18 and 28, and the 3rd IMD products caused by BS supporting carrier aggregation of Band 18 and Band 28 will not fall into the BS receive frequency range within Band 8 that is allocated in Japan. Therefore, the focus here will be on the harmonics and IMD falling into Bands 3, 9, 28 and 41.
With the performances of the current BS antenna system, transmit and receive path components, amplifiers, pre-distortion algorithms and filters, it is expected that the harmonics and IMD interference generated within the Band 3, 9 or 41 receiver would be well below the receiver noise floor eliminating the possibility of receiver desensitization, provided that Bands 18 and 28 BS transmitters do not share the same antenna with Band 3, 9 or 41 BS receiver.
On the other hand, it is recommended that Bands 18 and 28 BS transmitters should not share the same antenna with Band 3, 9 or 41 BS receiver, or Band 28 BS receiver for the affected frequency ranges if the aforementioned BS transmit configurations are used, in order to prevent BS receiver desensitization, unless the antenna path meets very stringent harmonics and 3rd order PIM specification so that the harmonics and PIM will not cause Band 3, 9, 28 or 41BS receiver desensitization.
6.3.10.1.3 ∆TIB and ∆RIB values
Given that CA_B18-B28 is low-low band combination, appropriate UE architecture would be quadplexer basis. As one can see in Figure 6.3.10.1.3-1, separation between Band 18 UL and Band 28 DL is only 12 MHz. In addition, Band 18 filter cannot provide steep attenuation toward lower frequency side. Therefore, it is expected that Band 28 UE would suffer from noise of Band 18 UL and we had considered that inter-band CA of this combo is almost impossible to keep commercial service of quality.
Figure 6.3.10.1.3-1: Frequency range of Band 18 and Band 28
However, it is expected that Lower Duplexer of Band 28 DL can provide good blocking characteristic from unwanted signal of Band 18 UL because separation between them is more than twice (27 MHz) of upper duplexer. Operator A in the figure can fortunately use both Lower and Higher Duplexer from perspective of frequency assignment. Therefore, quadplexer to perform CA_B18-B28 is much preferable to be implemented by [Band 18] + [Band 28 Lower DUP] as indicated by red line in Figure 6.3.10.1.3-1. Values of ∆TIB and ∆RIB would be standardized on the basis of such architecture of quadplexer.
For the reported IL values, additional IL values compared to single band operation could be assumed as shown in table 6.3.10.1.3-1:

As shown in table 6.4.1.2-2, no second order intermodulation products will fall to any 3GPP UL frequencies. Third intermodulation products may fall to UL frequencies of Bands 1-4, 9-10, 23, 25, 30, 33, 35-37, 39 or 40. As third intermodulation products may fall to own receive block (both for Band 2 and Band 4, highlighted in table 6.4.1.2-2), the desensitisation may be an issue.
Analysis in table 6.4.1.2-2 assumes BS is transmitting the whole DL frequency for both Band 2 and Band 4. Further analysis were made when two-tone third order intermodulation product will fall to own receive block for CC bandwidths agreed in the Work Item Description (WID): 5MHz, 10MHz and 15MHz for both operating bands plus 1.4 and 3MHz for Band 2. Two-tone third order intermodulation products were summarized in table 6.4.1-3 with assumptions shown in figure 6.4.1.2-1.

Taking into account CC bandwidths agreed in the WID, two-tone third order intermodulation product will fall to own receive block for CC1 and CC2 positions summarized in table 6.4.1.2-4. Considered scenarios are very pessimistic as studies are taking into account channel bandwidths. Taking into account transmission bandwidths (1.08, 2.7, 4.5, … MHz) the region where IMD would fall to receive band would be further reduced.

It is suggested BS transmitters supporting CA of Band 2 and Band 4 should not share the same antenna with Band 1, 2, 3, 4, 9, 10, 23, 25, 30, 33, 35-37, 39 or 40 BS receiver, unless the antenna path meets very stringent third order PIM specification so that the PIM will not cause Band 1, 2, 3, 4, 9, 10, 23, 25, 30, 33, 35-37, 39 or 40 BS receiver desensitization.
6.4.1.3 UE Co-existence studies for CA_2-4
The scope of the WID states that the specifications are done for 1 UL operation. Because of that IMD studies between the UL bands are not required for now. Study of UL 2nd and 3rd order harmonics frequencies is needed. Results of the harmonic study are presented in table 2.2-1. It can be observed that none of the 2nd or 3rd harmonic products fall into own DL bands. It can be noted that band 4 second harmonic extends to 3510 MHz which is the start frequency for band 22 and some harmonic power might land on band 22. Band 4 second harmonic also falls to band 42. Band 2 second harmonic falls to band 43.

From table 6.5.2.1.2-2, it is observed that:
• 2nd and 3rd order harmonics don’t fall into any 3GPP defined BS receive frequencies,
• 2nd order IMD will fall into BS receive frequencies of Band 42, 43,
• Two-tone 3rd order IMD will fall into BS receive frequencies of Band 5, 6, 8, 13, 14, 18, 19, 20, 26, 27 and 44
• Three-tone 3rd order IMD will fall into BS receive frequencies of Band 11, 21.
On the other hand, the issue of possible desensitisation due to IMD fall down would happen whenever a BS supports these frequencies simultaneously, regardless of whether CA is supported or not. Thus this is not a CA specific issue and BS vendors are requested to configure a BS appropriately when the bands mentioned above are operated with Band 1 and 11.

From the table, it is observed that:
• 2nd order harmonics will fall into BS receive frequency of Band 2, 25, 33, 35, 37, 39,
• 3rd order harmonics don’t fall into any 3GPP defined BS receive frequencies,
• 2nd order IMDs don’t fall into any 3GPP defined BS receive frequencies,
• Two-tone 3rd order IMDs will fall into BS receive frequencies of Band 22, 23, 34 and 42
• Three-tone 3rd order IMDs will fall into BS receive frequencies of Band 8, 21.
On the other hand, the issue of possible desensitisation due to IMD fall down would happen whenever a BS supports these frequencies simultaneously, regardless of whether CA is supported or not. Thus this is not a CA specific issue and BS vendors are requested to configure a BS appropriately when the bands mentioned above are operated with Band 8 and 11.

For the 3-tone IMD analysis the maximum transmission as defined in table 6.5.4.1.1-1 is considered. None of the harmonics of one band fall into the receive band of the other.
It can be seen in the table that 2nd order IMD products may fall into BS receive band 5, 6, 8, 18, 19, 20, 26 and 27. The 3rd order IMD products may fall into BS receive bands of 2, 3, 4, 7, 9, 10, 22, 24, 25, 35, 38, 41, 42 and 43. However, when the impact of maximum bandwidth is considered, the 3rd order IMD products do not fall into the BS receive of Band 7 and 22.
It should be noted that bands 6, 9, 18, 19, 24, 25, 35, 41 and 42 are not intended for use in the same geographical area (country) as the band combination Band 7 and Band 22. This leaves bands 2, 3, 5, 7, 8, 20, 22, 26, 38 and 43 to consider for IMD products.
It is recommended that Bands 7 and 22 BS transmitters do not share the same antenna with band 2, 3, 5, 8, 20, 26, 38 and 43 BS receivers so that the antenna PIM will not cause Band 2, 3, 5, 8, 20, 26, 38 and 43 BS receiver desensitization.

389f9b67c003a620147a83200e3331ae | 36.851 | 7.2.1.1.2 Co-existence studies for CA_1-41 | Table 7.2.1.1.2-1gives the intermodulation products for band 1 + band 41 CA with 2 DLs. For the IMD analysis the maximum transmission as defined in table 7.2.1.1.1-1 is considered. None of the harmonics of one band fall into the receive band of the other. The intermodulation products generated by two operating bands do not impact the own receiver since TDD BS cannot transmit and receive simultaneously in a single band.
It can be seen in the table that 2nd order IMD products may fall into BS receive band 31. The 3rd order IMD products may fall into BS receive bands of 1, 3, 4, 7, 9, 10, 23, 24, 30, 33, 34, 36, 37, 38, 39, 40 and 41. However, when the impact of maximum bandwidth is considered, the 3rd order IMD products do not fall into the BS receive of Band 1, 23, 30, 33, 34, 36, 37, 39, 40.
It should be noted that Bands 4, 7, 10, 24, 31 and 38 are not intended for use in the same geographical area as Band 1 and Band 41. This leaves bands 3, 9 and 41 to consider for IMD products.
Currently Bands 3, and 9 are used in the same geographical area as Bands 1 and 41. It is recommended that Bands 1 and 41 BS transmitters do not share the same antenna with Band 3 or 9 BS receivers so that the antenna PIM will not cause Band 3 or 9 BS receiver desensitization. A TDD BS cannot transmit and receive simultaneously in a single band so the own B41 receiver is protected. However, it is not recommended that different band 41 operators share the same antenna as a Band 1 transmitter unless the operation is synchronized.

It can be seen from table 7.2.2.1.2-1 that some 2nd IMD products caused by BS supporting carrier aggregation of Band 1 and Band 42 fall into the BS receive band of Bands 11 and 21, while some 3rd IMD products fall into the BS receive band of Bands 1, 5, 6, 8, 12, 13, 14, 17, 18 , 19, 20, 22, 23, 25, 26, 27, 28, 30, 33, 34, 36, 37, 39, 40, 42, 43 and 44. Note that the calculation in table 7.2.2.1.2-1 (except the last row) assumes the BS transmits the whole 60 MHz DL frequency of Band 1 and the whole 200 MHz DL frequency of Band 42. However even if the BS only transmits up to 20 MHz DL in Band 1 and up to 20 MHz DL in Band 42 as stated in Table 7.2.2.1.1-1, the 3rd IMD products may still fall into the BS receive band of the Bands 5, 6, 8, 12, 13, 14, 17, 18, 19, 20, 22, 26, 27, 28, 42, 43 and 44 as shown in the last row in table 7.2.2.1.2-1.
It should be noted that Bands 12, 13, 14, 17 is not intended for use in the same geographical area as Band 1 and Band 22 is not intended for use in the same geographical area as Band 42. Consequently, the focus here will be on the harmonics and IMD products falling into Bands 5, 6, 8, 18, 19, 20, 26, 27, 28, 42, 43 and 44.
TDD BS does not transmit and receive simultaneously, so the BS’s own band 42 receiver and other synchronized band 42 receivers would not be interfered. With the performances of the current BS antenna system, transmit and receive path components, amplifiers, pre-distortion algorithms and filters, it is expected that the IMD interference generated within the Band 5, 6, 8, 18, 19, 20, 26, 27, 28 or unsynchronized 44 receiver would be well below the receiver noise floor eliminating the possibility of receiver desensitization,
Therefore, it is recommended that Bands 1 and 42 BS transmitters should not share the same antenna with Band 5, 6, 8, 18, 19, 20, 26, 27, 28, unsynchronized 42, unsynchronized 43 or unsynchronized 44 BS receiver, unless the antenna path meets very stringent 3rd order PIM specification so that the PIM will not cause Band 5, 6, 8, 18, 19, 20, 26, 27, 28, unsynchronized 42, unsynchronized 43 or unsynchronized 44 BS receiver desensitization.

For the UE aspect, the UL harmonic frequencies of Band 3 and Band 40 does not locate within the UE receive bands of interest in the DL. Therefore we can conclude that there is no issue on harmonic interference.

It can be seen from Table 7.2.3.1.2-2 that the 2nd order IMD products may fall into the BS receive band of Band 31. The 3rd IMD products caused by BS supporting carrier aggregation of Band 3 and Band 40 may fall into the BS receive bands of Band 1, 2, 3, 4, 9, 10, 11, 21, 25, 30, 33, 35, 36, 37, 39, and 40. However, when the impact of maximum bandwidth is considered, the 3rd order IMD products do not fall into the BS receive of Band 1, 3, 4, 9, 10, 33, 36, and 37.
It should be noted that Bands 2, 4, 9, 10, 11, 21, 25, 30, 31, and 35 are not intended for use in the same geographical area as Band 3 and 40. Consequently, the focus here will be on the harmonics and IMD products falling into Bands 39, and 40.
TDD BS does not transmit and receive simultaneously, so the BS’s own band 40 receiver and other synchronized band 40 receivers would not be interfered. With the performances of the current BS antenna system, transmit and receive path components, amplifiers, pre-distortion algorithms and filters, it is noted that the harmonics and IMD interference generated in common signal paths within Band 39, if unsynchronized with band 40 may not be well below the receiver noise floor eliminating the possibility of receiver desensitization. Operating band 39 together with band 3 and 40 CA it is either recommended to synchronize bands 39 and 40 carriers or to have at least one of the three carrier signals using separate feeders.

It can be seen from Table 4 that the 2nd order IMD products will fall into the BS receive bands of Band 11 and 21.

However, when the impact of maximum bandwidth is considered, the 3rd order IMD products do not fall into the BS receive of Band 5, 18, 19, 20, and 26.
It should be noted that Bands 2, 6, 11, 18, 19, 21, 25, 30, and 31 are not intended for use in the same geographical area as Band 8 and 40. Consequently, the focus here will be on the harmonics and IMD products falling into Bands 8, 33, 35, 37, 39, 40 and 43.
TDD BS does not transmit and receive simultaneously, so the BS’s own band 40 receiver and other synchronized band 40 receivers would not be interfered. With the performances of the current BS antenna system, transmit and receive path components, amplifiers, pre-distortion algorithms and filters, it recommended that the harmonics and IMD interference generated within the Bands 8, 33, 35, 37, 39, 43, and unsynchronized Band 40 generated in common signal paths is carefully considered. (E.g. by separating band Tx path from the other bands in the feeder system).

It can be seen from table 7.2.5.1.2-1 that some 2nd IMD products caused by BS supporting carrier aggregation of Band 3 and Band 42 fall into the BS receive band of Bands 3, 4, 9, 10, 24 and 43, while some 3rd IMD products fall into the BS receive band of Bands 1, 2, 3, 4, 9, 10, 22, 23, 24, 25, 33, 34, 35, 36, 37, 39, 42 and 43. Note that the calculation in table 6.5.2.1.2-1 (except the last row) assumes the BS transmits the whole 20 MHz DL frequency of Band 3 and the whole 200 MHz DL frequency of Band 42. However even if the BS only transmits up to 20 MHz DL in Band 3 and up to 20 MHz DL in Band 42 as stated in Table 7.2.5.1.1-1, the 3rd IMD products may still fall into the BS receive band of the Bands 22, 42, 43 as shown in the last row in table 7.2.5.1.2-1.
7.2.5.1.3 ∆TIB and ∆RIB values
Following relaxations are allowed for the UE which supports inter-band carrier aggregation of Band 3 and Band 42. These relaxations are derived from the assumption that harmonic trap filter for Band 3 is not considered. The relaxations based on the implement of harmonic trap filter are FFS.

For the IMD analysis the maximum transmission as defined in table 7.2.6.1.1-1 is considered. It can be seen from the table that the 2nd harmonics of BS transmitting in Band 26 may fall into the BS receive band of Bands 3, 4, 9 and 10 and the 3rd harmonics of BS transmitting in Band 26 may fall into the BS receive band of Bands 38 and 41, while the 2nd IMD products caused by BS supporting CA of Band 26 and Band 41 may fall into the BS receive band of Band 3, 4, 9, 10, 22, 24 and 42, and the 3rd IMD products may fall into the BS receive band of Bands 5, 6, 8, 12, 13, 14, 17, 18, 19, 20, 26, 27, 28, 38, 41 and 44. Note that Bands 7, 8, 20 and 38 are not intended for use in the same geographical area as Bands 26 and 41. Therefore, sharing antenna for CA operation between Band 26 and Band 41 is not recommended. In addition, when one deploys CA_26-41 operation in certain region, these co-existence studies should be taken into account because harmonics and IMDs could fall into twenty bands in total.

389f9b67c003a620147a83200e3331ae | 36.851 | 7.2.6.1.2.1 B26 UE receiver harmonic mixing problem | This CA combination is associated with an undesired property that the B41 UL carrier can align with 3rd order harmonic of B26 DL carrier, as shown in Table 7.2.6.1.2.1-1, which could potentially cause B26 desensitization problem if simultaneous Tx/Rx would be operated, due to the known harmonic mixing problem in typical receiver design.

B26 DL
B26 DL x3
B41
Range (MHz)
859 - 894
2577 - 2682
2496 – 2690
Using the commonly adopted L/H band UE reference architecture, as shown in Figure 7.2.6.1.2.1-1, the B41 UL power at B26 LNA input is estimated to be around -33 dBm. Considering that a typical receiver path (excluding off-chip filters) 3rd order harmonic rejection performance would not be better than 20 dB (which includes 9-dB rejection from switching mixer and less than 10 dB from matching selectivity), the desensitization level is expected to be more than 50 dB which can virtually nullify the receiver function. On the other hand, if a transceiver could provide up to 20-dB 3rd order harmonic rejection, to avoid self-desensitization, the isolation from B41 PA output to B26 LNA input shall still be better than 100 dB, which likely cannot be achieved even with additional bandpass filters cascaded before LNA.
Figure 7.2.6.1.2.1-1 UE reference architecture for self-desensitization analysis
Although adding bandpass filters can help reduce desensitization level, it will also introduce additional insertion loss to B26 receiver, yet the MSD is expected to be still higher than 20 dB due to finite PCB isolation. Therefore, it is suggested network to avoid simultaneous Tx/Rx operation when the B41 UL and B26 DL 3rd harmonic alignment condition occurs.
7.2.6.1.3 ∆TIB and ∆RIB values

It can be seen from table 7.2.7.1.2-2 that 2nd harmonics caused by BS supporting carrier aggregation of Band 3 and Band 38 may fall into the BS receive band of Bands 43, while none 3rd harmonic will fall into the BS receive band of currently defined 3GPP Bands.
It can be seen from table 7.2.7.1.2-2 that 2nd IMD products caused by BS supporting carrier aggregation of Band 3 and Band 38 may fall into the BS receive band of Bands 12-14, 17, 26-28 and 44, while 3rd IMD products may fall into the BS receive band of Bands 2, 7, 22, 25, 35, 38, 39, 41 and 42 (assuming BS transmits up to 20 MHz DL in Band 3 and up to 20 MHz DL in Band 38).
As BS cannot transmit and receive in Band 38 at the same time, the 3rd IMD products problem in receive band of Band 38 is not an issue.
7.2.7.1.3 ∆TIB and ∆RIB values
The reported additional IL (Insertion Loss) values, based on implementation/simulation data, under ETC (Extreme Temperature Conditions) for combining band 3 and band 38, for each of the Tx and Rx paths, are shown in Table 7.2.7 .1.3-1.

Table 7.2.8.1.2-1 shows the second and third order DL harmonics and intermodulation products when two simultaneous DLs are active in Band 19 and Band 42.It can be seen from table 7.2.8.1.2-1 that some 2nd harmonic products of Band 19 fall into the BS receive band of Bands 3, 4, 9 and 10, while some 3rd harmonic products fall into the BS receive band of Bands 41.

It can be seen from table 7.2.8.1.2-2 that some 2nd IMD products caused by BS supporting carrier aggregation of Band 19 and Band 42 fall into the BS receive band of Bands 7, 38 and 41, while some 3rd IMD products fall into the BS receive band of Bands 3, 4, 5, 6, 8, 9, 10, 12, 13, 14, 17, 18, 19, 20, 22, 24, 26, 27, 28, 42, 43 and 44. Note that the calculation in table 7.2.8.1.2-2 (except the last row) assumes the BS transmits the whole 15 MHz DL frequency of Band 19 and the whole 200 MHz DL frequency of Band 42. However even if the BS only transmits up to 15 MHz DL in Band 19 and up to 20 MHz DL in Band 42 as stated in Table 7.2.8.1.1-1, the 3rd IMD products may still fall into the BS receive band of the Bands 3, 4, 8, 9, 10, 20, 22, 24, 42, 43 as shown in the last row in table 7.2.8.1.2-2.
It should be noted that Bands 4, 7, 10, 20 and 24 are not intended for use in the same geographical area as Band 19 and Band 22 is not intended for use in the same geographical area as Band 42. Consequently, the focus is on the IMD products falling into Bands 3, 8, 9, 38, 41, 42 and 43, where receiver desensitization might be an issue.
TDD BS does not transmit and receive simultaneously, so the BS’s own band 42 receiver and other synchronized band 42 receivers would not be interfered. Therefore, it is recommended that Bands 19 and 42 BS transmitters should not share the same antenna with Band 3, 8, 9 or unsynchronized Band 38, 41, 43 BS receivers, unless the antenna path meets very stringent 3rd order PIM specification so that the PIM will not cause Band 3, 8, 9 or unsynchronized 38, 41, 43 BS receivers desensitization.

It can be seen from table 7.2.7.1.2-2 that 2nd harmonics caused by BS supporting carrier aggregation of Band 3 and Band 38 may fall into the BS receive band of Bands 43, while none 3rd harmonic will fall into the BS receive band of currently defined 3GPP Bands.
It can be seen from table 7.2.7.1.2-2 that 2nd IMD products caused by BS supporting carrier aggregation of Band 3 and Band 38 may fall into the BS receive band of Bands 12-14, 17, 26-28 and 44, while 3rd IMD products may fall into the BS receive band of Bands 2, 7, 22, 25, 35, 38, 39, 41 and 42 (assuming BS transmits up to 20 MHz DL in Band 3 and up to 20 MHz DL in Band 38).
As BS cannot transmit and receive in Band 38 at the same time, the 3rd IMD products problem in receive band of Band 38 is not an issue.
7.2.7.1.3 ∆TIB and ∆RIB values
The reported additional IL (Insertion Loss) values, based on implementation/simulation data, under ETC (Extreme Temperature Conditions) for combining band 3 and band 38, for each of the Tx and Rx paths, are shown in Table 7.2.7 .1.3-1.
