luis_pereira87 303e724845 Always set firstActive/defaultBWP 
Always set the firstActive and defaultBWP in the initial
cellGroupConfig. This is necessary to make the Quectel accept the
handover RRCReconfiguration; it seems that this also works reliably in
normal connection set up, so we can add it.

luis_pereira87 cbf8489707 Switch to BWP where RA is configured when Msg3 contains MAC CE for C-RNTI 
Switch to BWP where RA is configured, typically in the InitialBWP
At this point, MAC CE for C-RNTI received at gNB, UE already switched and triggered RA in that BWP, need to do BWP switching also at gNB for that C-RNTI

luis_pereira87 2c1f32b6e6 Do not extract CSI report if PUCCH format 2 CRC check fails in polar decoder 
This fix prevents the scheduler to process a wrong CSI feedback message, for example, it avoids the scheduler to compute a wrong MCS from CQI or a wrong RI from CQI

Luis Pereira 04c6c34d24 NR MAC stats: make more compact, update CI checker 
- show MAC bytes in one line
- add MCS table idx
- show ulsch errors before ulsch DTX (as in DL)
- show if UE in-sync/out-of-sync
- show CU UE ID next to RNTI to stats

Since we modify the format of the statistics, fix the format in the retx
checkers of the CI.

luis_pereira87 87e8ba0ba1 Fix FAPI CoreSetType enumeration options after the fix on the description made by SCF 
SCF FAPI 222.10.02 had a bug on the description of CoreSetType:
0: CORESET is configured by the PBCH or SIB1
(subcarrier 0 of CRB0 for DMRS mapping)
1: otherwise (subcarrier 0 of CORESET)

That was fixed in SCF 222.10.04:
0: CORESET is configured by the PBCH or SIB1
(subcarrier 0 of the CORESET)
1: otherwise (subcarrier 0 of CRB0 for DMRS mapping)

That wrong description created a misunderstanding, to overcome it we "wrongly" added a third value. This commit fixes that and aligns the CoreSetType with FAPI 222.10.04

luis_pereira87 3e80765668 Trigger UL Failure if Ack of Msg4 not received 
The UE will trigger new RA either with MAC CE C-RNTI or with new RRCSetupRequest:
- MAC CE C-RNTI: The ul_failure_timer will be reset
- RRCSetupRequest: New UE will be created and the previous one will be deleted

luis_pereira87 3f22837d88 Fix gNB RA procedures when Msg4 Ack not received 
When the gNB does not receive PUCCH with Ack for Msg4 we have to consider Msg4 received by the UE, so we need to apply the CellGroupConfig sent to the UE.
There are two scenarios:
1 - The UE never decoded PDSCH for Msg4, the RA will fail because RA Contention Resolution timer, the UE will come with a new RA with new RRCSetupRequest
2 - The UE decoded PDSCH for Msg4, and if SR does not work and no resources for PUSCH, it will trigger RA with MAC CE C-RNTI in Msg3 (so, gNB must be ready for it)

luis_pereira87 f0df1ccb53 Hotfix: swap UIDs after RRCReestablishment 
The CellGroup is created considering UID, for example:
'pucchres0->startingPRB = 8 + uid;' and since we keep the CellGroup from
the previous RNTI/UID we should keep also the previous UID.

Considering the scenario where a UE did successful RRCReestablishment,
it was getting uid = 1, and uid = 0 was removed.
When another UE connected, it was getting UID = 0 (because 0 was already
free), and so the PUCCH 0 resource was conflicting with the first UE.

On that occasion, also correct the comment that describes the code, as
it was wrong/misleading.
