R4-021603 Response to LS on the definition of CQI (TSG RAN WG1, R1-02-1198)

This is a response to R4-021360. WG1 has studied and revised the definition of CQI as follows:

Based on an unrestricted observation interval, the UE shall report the highest tabulated CQI value for which a single HS-DSCH sub-frame formatted with the transport block size, number of HS-PDSCH codes and modulation corresponding to the reported or lower CQI value could be received in a 3-slot reference period ending 1 slot before the start of the first slot in which the reported CQI value is transmitted and for which the transport block error probability would not exceed 0.1.

Decision: The LS is noted, no response is required

R4-021630 LS response on uplink DPCCH transmission start timing in Hard Handover (TSG RAN WG1, R1-02-1188)

Panasonic will present a CR covering this issue.

R4-021416 LS on TX diversity on radio links in the active set (TSG RAN WG1, R1-02-1159)

This LS is sent to WG2, cc WG4.

25.331 Rel5 provides signalling indicating the use or not of TX diversity per radio link basis. This wasn't available to the UE before, WG1 has corrected its specifications to require the UE to operate in TX diversity only in the links were its is used. WG1 proposes a small correction to 25.331 to fully align the specifications.

Edgar Fernandes (Motorola) noted that there are performance implications, WG4 needs to study the issue, even if the LS is only sent to WG4 as a copy.

Decision: The LS is noted
