4.2 WDS Architecture
The key attribute of WDS is its capability to enable the radio interface of a number of BS to be remote, and hence support a distributed multi-carrier and multi-operator network. WDS is in general an active device and includes, but is not limited to, one or multiple RF front-end (LNA, MCPA) and RF transmission interfac...

The simulation programme and hence the results set out to demonstrate two specific areas of interest. 1. The range of input levels available to a system which would feed a WDS system and its relationship to current specifications. 2. The margin required with the introduction of WDS over a number of output power classes...

5.6.1 ACLR
It was found that a 3dB margin is typically required to accommodate the effects of the inclusion of a WDS to an existing Base Station set-up. There is a minor difference in performance which is dependent on WDS input signal level. With low input power signal levels, as demonstrated in the example with 20dBm output powe...

5.6.2 Occupied Bandwidth / Out of Band Emissions
Single carrier testing with WDS output power of 43dBm show that there is negligible impact on the occupied bandwidth or output emissions due to the inclusion of WDS.
198feca7a70995985a5cc7f203dbedb2
25.867
5.6.3 Conclusions
The simulations results show the impact of WDS from an RF perspective on most critical downlink parameters, with certain requirements at BS interface point. Any effects can be measured over a range of different power classes and implementation scenarios in order to define the interface conditions required to satisfy th...

7 Operation & Maintenance
In order to identify any possible impact of a communication interface between WDS and other network elements R3-011933 [Ref. 2] and R5-010481 [Ref. 3] were discussed within RAN 3 and SA5 respectively. Either working group said that no impact was found on existing specs because of WDS, and it appeared that existing spec...

8 Location Services (LCS)
In order to assess any impact of WDS on location services, the co-existence between WDS and location services (LCS) is discussed in this section. Three methods for location services are currently specified in TS 25.305 – Stage 2 Functional Specification of Location Services in UTRAN. These are OTDOA, Cell ID based posi...

8.1 OTDOA/IPDL
The OTDOA/IPDL methods are based on the measurements of the UTRA pilot signal (CPICH) made by the UE and the Location Measurement Unit (LMU). The position of the UE is estimated by using the observed time difference of arrival from three or more base stations. As measurements are made by the UE who then reports them t...

8.3 Network Assisted GPS
These methods make use of UE, which are equipped with radio receivers capable of receiving signals from the Global Positioning System (GPS). Therefore there are no implications to a WDS enhanced network.
198feca7a70995985a5cc7f203dbedb2
25.867
8.4 Summary of WDS impact on LCS
From the above discussion it is clear that no impact on LCS is envisaged due to inclusion of WDS The system calculations required in order to accommodate the provision of LCS information to the network rely primarily on the UE or high level network systems specifically dedicated to LCS. The only provision for inclusion...

9.1 WDS positioning discussion

They are NOT used to complement radio coverage of a BS (so-called simulcasting), and therefore provide consistent and reli...

9.2 Potential Impact of WDS Standardisation
The Feasibility Study has highlighted the potential impact of WDS standardisation based on existing BS specifications TS25.104/TS25.141, with specific reference to the interface point between BS and WDS, where a more stringent performance than that of compliant BS may be required in order to guarantee full compliance t...

10 Conclusions and Way Forward
The Feasibility Study has shown how WDS performance may impact on a 25.104 compliant generic BS, on a limited number of basically important parameters and, more in general, in the network configuration. A new set of compliance parameters should be investigated as a consequence of BS classification and further definitio...
