Fix "Received Nack" log for Msg4/MsgB and minor improvement in RA logs Fix "Received Nack" log for Msg4/MsgB, in 4-Step RA. When there is a Msg4 NACK, we have this log: [NR_MAC] (UE 91db) Received Nack in MsgB, preparing retransmission! This MR fixes the message and now works correctly both in 4-Step RA and 2-Step RA. Other additional but minor improvement in RA logs.
