See merge request oai/openairinterface5g!1451
This merges the following MRs:
- MR !1436 fairRR LTE scheduler fixes: should make the connection more stable, less UL retransmissions
- MR !1386 phy sync improvements: the 5G NR UE should sync better
- MR !1361 FDD support (no traffic): adds FDD support for the scheduler, but heavy traffic has not been tested
- MR !1447 using uid for PUCCH RRC conf: use the RRC UID to decide on PUCCH resources, should in particular avoid the "PUCCH straddles DC carrier" assert
- fix for 5G F1 RFsim test fail
Previously, we thought the memset in the nr_ue_dl_indication()
was causing issues / exposing a race. This is not the case. The
memset is not problematic, the issue is that in the emulate_l1
mode we were not always configuring the DCI nbits before handling
the DCI when we are pushing high (15 Mbps) throughput traffic.
Overwriting sched_pusch information at that stage would in particular
lose information on the current frame/slot. Overwriting sched_pusch with
the retInfo structure is already done at the end of
allocate_ul_retransmission(), and is therefore not necessary at this
stage.
We compute the preferred DL TDAs when receiving the cellGroup from the
RRC. However, in F1 and the RFsim, it seems that the scheduler tries to
access the preferred DL TDAs before they have been set after receiving
the cellGroup. In this commit, add a simple check to verify the
preferred TDA has been set up.
Instead of conditionally calling the pucch_scheduler
we now only call the functions we need from the stub
function directly. This is better because we are not
modifying the OAI MAC layer code and ensuring that we
are not calling the pucch_scheduler twice for the same
sfn/slot
Adding error checking before indexing in mac layer harq array
Adding error checking before writing ul_harq_sfn_slot

Made a "static" free_uci_inds() actually static
