- PDCP reestablishment on CUCP (DRBs) triggering Bearer Context Modification procedures over E1
- Performing PDCP reestablishment for requested DRBs on CUUP
- Introduced function to notify re-establishment to CU-UP
- removed call to PDCP reestablishment for the DRBs on CUCP (it's done on CUUP)
cuup_notify_reestablishment:
- to fetch PDU session to setup in E1 following logic as in e1_send_bearer_updates
- fill bearer context modification request with stored F1-U tunnel information
during E1 reestablishment, otherwise it would initialized to 0 by default
- update GTP tunnel with the stored configuration after E1 reestablishment
The following ASSERT is tirggered while testing 16 UE setup.
Assertion (NPRB>0 && (NPRB + RBstart <= BWPsize)) failed!
In PRBalloc_to_locationandbandwidth0() /home/ran/common/utils/nr/nr_common.c:286
Illegal NPRB/RBstart Configuration (1,48) for BWPsize 48
Corrected the get_start_stop_allocation calculation to fix the issue.
The implementation was wrong. The rbstop shall be the last rb that could
be allocated. Also the following two conditions are taken care
rbStart needs to be strictly smaller than rbStop
rbStart+rbSize needs to be smaller or equal to rbStop
The problem was that we confounded both conditions, so rbStart could
be equal to rbStop, which then leads to one PRB being allocated at the end.
Setting rbStop to BWPsize - 1 and making sure the above two conditions are
true does not make it lead to wrong allocations anymore.
- many structs and definitions are overlapping between the two different E1 procedures
- introduced naming specific to E1 Bearer Context Modification to improve readability
- grouped SDAP and PDCP configuration IEs for better reusability and readability
- introduced functions to set and get default PDCP config (DRBs and Bearer Contexts)
find_or_next_pdu_session:
- find_or_next_pdu_session refers to the E1 Bearer Context Modification Request
-- therefore it has to return pdu_session_to_mod_t* and takes in input e1ap_bearer_mod_req_t *
see !MR2545 for more context
- triggered by RRC reconfiguration events according to clause 5.3.5.6.5 of TS 38.331
- This procedure does QoS flow to DRB mapping according to clause 5.3.1 of TS 37.324
- QoS flows to DRBs to be released are also handled
Fix for CI runtime error: left shift of 1 by 31 places cannot be represented in type 'int'
Fix for CI runtime error: left shift of 128 by 24 places cannot be represented in type 'int'
- Phy configuration will be prepared by MAC
- Sidelink preconfiguration parameters passed from RRC->MAC
- Only 1 SSB TA allocation used
- psbch payload prepared by MAC after receiving the tx slss req
For different reasons, the frame/slot numbers might jump (e.g., gNB and
RU machines not properly synced). The scheduler would assert for PUCCH
allocations. Handle this gracefully by printing an error message, and
resetting the PUCCH structure.
This commit allows the gNB to handle PDU sessions that the core requests
to setup during the NGAP Initial UE Context Setup. Previously, we only
managed them as part of PDU Session Resource Setup Request.
The RRC will, depending on whether a PDU session is in the NGAP Initial
UE Context Setup, either directly trigger the Security Command, or first
do a bearer setup at the CU-UP. Some asserts have been lifted, as now
the PDU sessions might be present before the RRC Connection is fully
established.
Implement the correct forwarding of the bearers in an F1 UE Context
Setup Request message.
This solves bug #672.
- 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.
