Anyone has the issue in SA system that contention resolution is successful but no RrcSetup after that and after t300 expiration rrc establishment failed?
If I’m not wrong msg4 contention resolution just means that UE detected UE identity on PDCCH properly but RRcSetup should be on PDSCH.
Could be this some issue with PDSCH decoding? Any idea?
Ok, then try going all the UE layers: try at phy layer see if pdsch is there, then go at mac layer see if pdsch is there, then go at rlc layer see if pdsch is there then go at RRC layer and see if pdsch is there.
RRC setup is quite a big message.
So probably you will have to analyse several Sequence numbers.
At each layer.
You have to make sure the DCIs are for your UE scrambled with correct RNTI.
