R4-021425 LS on the value of Maximum allowed UL TX power in case of correct behaviour at time-out test of Random Access (TSG T WG1 RF SWG, T1R020308)

T WG1/RF shows that the current test for "Correct behaviour at time-out during the random access" might result in fail for UEs in accordance with the specifications. T WG1/RF proposes to change the value of the "Maximum allowed UL TX power" in this test from 0 dBm to 33 dBm so that a UE measuring CPICH RSCP with a +6dB error (accuracy within the specified limits) doesn't reach the "Maximum allowed UL TX power" before transmitting the complete preamble cycle, a situation that will make the test fail. T WG1/RF asks WG4 to endorse this change.

The value of 33 dBm is questioned, DoCoMo agreed that a lower value can be used, there is no special concern about it. Nobuto Arai (DoCoMo) noted that the CRs for WG4 specifications are not presented yet, and asks the group to decide if a CR to 25.133 is required or a change to T1RF is sufficient. See R4-021651 in section 5.7 of this report.

Decision: The LS is noted
