So the number of timeslot i should be 0, 1,…,6. In addition, for the 1.28 Mcps chip rate TDD option, the DL reference measurement channel for 144kbits/s need two timeslots, each consists of 8 DPCH(SF=16).So the number of DPCH in each active TS should be 8.
For the 1.28 Mcps chip rate TDD option, each TS consists of 864 chips, but 16 chips is for Guard Period, so the measuring thermal power should over 848 active chips. |

1cc4b09fd057c9a5cf925fb9b5a5f4e7 | 25.945 | 9.3.3.6 Explanation difference | For the 1.28 Mcps chip rate TDD option, one frame(10ms) consists of two subframes(5ms), and one subframe consists of 7 timeslots, (the structure of the subframe is shown in section7.2.1 of 3GPP TR 25.928), so the number of timeslot i should be 0, 1,…,6.
The frequency stability is a characteristic of the local oscillator and will not change, if the number of DPCH is varied. In these cases, it is felt that the use of only 1 DPCH will make the measurement easier and, at least for some parameters, more exact. Therefore, it is proposed to specify the test for frequency stability with 1 DPCH only also in the case of 1.28 Mcps TDD option. |

1cc4b09fd057c9a5cf925fb9b5a5f4e7 | 25.945 | 8.3.5.2.4.2 Procedure | Measure the power of the BS output signal chipwise (i.e. averaged over time intervals of one chip duration) over the transmit off power period starting 11 chips before the start of the receive time slot TS i = UpPCH, and ending 8 chips before the next transmit time slot TS i = 4 starts, and with a measurement filter that has a RRC filter response with a roll off = 0,22 and a bandwidth equal to the chip rate. If the power measuring equipment is based on signal sampling, the sampling theorem shall be met. In this case, the power is determined by calculating the RMS value of the signal samples taken at the measurement filter output over one chip duration. |

1cc4b09fd057c9a5cf925fb9b5a5f4e7 | 25.945 | 8.3.6.1.4.2 Procedure | 1) Measure the power of the transmitted signal with a measurement filter of bandwidth 30 kHz. The characteristic of the filter shall be approximately Gaussian (typical spectrum analyzer filter). The center frequency of the filter shall be stepped in contiguous 30 kHz steps from a minimum frequency, which shall be (2,4 – 0,015) MHz below the assigned channel frequency of the transmitted signal, up to a maximum frequency, which shall be (2,4 – 0,015) MHz above the assigned channel frequency of the transmitted signal. The time duration of each step shall be sufficiently long to capture one active time slot. The measured power shall be recorded for each step.
2) Determine the transmitted power within the assigned channel bandwidth by accumulating the recorded power measurements results of all steps with center frequencies from (0,8 – 0,015) MHz below the assigned channel frequency up to (0,8 – 0,015) MHz above the assigned channel frequency.
3) Determine the total transmitted power by accumulating the recorded power measurements results of all steps.
4) Calculate the following ratio:
transmitted power within the assigned channel bandwidth acc. to (2) / total transmitted power acc. to (3). |
