luis_pereira87 089d1ec49e Tutorials: add support for 'default'/"empty" DNN to CN5G configuration file 
Add support for 'default' DNN to CN5G configuration file (that will also be used when DNN is not available, "empty" DNN). This configuration will allow most of the COTS UE to get PDUSession without any APN configuration made by the user

The 'default'/"empty" DNN configuration support was added in https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-amf/-/merge_requests/343

This prevents the UE to use an outdated timing_advance after a re-sync. It prevents the UE to send a PRACH with a wrong TA, thus preventing a RAPID mismatch in Msg2 (example: '[UE 0][RAPROC][0.0] Received RAR preamble (29) doesn't match the intended RAPID (30)')

normal connection set up, so we can add it.

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 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)
 2023-12-19 07:45:44 +00:00
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.
