DSCH Failure

On HARQ ID 0 with QPSK modulation and TBS 365 their was a DSCH Failureand so was retransmitted on the same HARQ ID using the same modulation.

RRC Connection Latency Calculation

Time of RAB Setup Time of RRC Connection Request [43.456 41.568 = 1.88]However, 5 to 6 calls should be made to calculate average RRC connection latency.
