MR890 : moving the OFDM phase rotation from RU to DU
Moves the recently introduced phase rotations from RU to DU.
This is important for setups that do not use the monolithic mode (like Benetel RRU).
MR944 : fix pdsch low prb
Fix for DLSCH decoding for low TBS and for ULSCH.
In the UE, DLSCH decoding stats are printed periodically for every 64 frames.
DLSCH decoding is skipped if UE receives retransmission for successfully decoded CW.
MR946 : S1ap bugfix rab setup
Fix a bug in S1AP
MR951 : CI NSA FR1 logging and reporting update
Enhancement of gNB html + log report showing (RAPROC PUSCH check, dlsch and ulsch statistics)
M954 : Mac fixes wk45 2
Hotfix: preserves "low" delay (20-30ms) and correct HARQ retransmissions by disabling timing advance (TA)
Reduces log level, compiler warning, correct TA condition
MR936: nr_fdd_if_fix
- Add support for 5G NR FDD bands and introduce configurable IF frequencies (esp. on nrUE) with configurable UL-DL-frequency offset.
MR940: dongzhanyi-zte-develop2
- Solved the problem that UE UL LDPC code can only process data within 8 code blocks (the UE UL LDPC code could only process data within 8 code blocks. If there were more than 8 code blocks, an error would occur)
MR943: NR_UE_MAC_scheduler
- Dynamic calculation of slot for PUSCH transmission based on slot offset k2. PUSCH slot is no longer hard-coded to 8.
- Support for multiple UL allocations in a frame by supporting a ul_config_request per UL slot.
- Support for multiple PDUs per slot
- Fixes for a few UE crashes/assertion failures due to invalid DCI received
- UE scheduler code clean-up
If UE receives retransmission for already decoded PDSCH, it skips decoding and sets ACK directly.
And adding PDSCH decoding stats and printing then every 64 frames for CI purpose
Integration 2020 wk45 (2) comprising:
MR937:Nr dl sched fixes
-restore old phytest scheduler behavior
-correct TA scheduling
-correct SSB
-shorten interface of `nr_fill_nfapi_dl_pdu()`
-Track RB allocation on symbol basis (bitmap)
-add a `remove_nr_ue_list()`, could be used instead of MR !934
MR910:5G SA NAS messages
- 5G SA nass messages and a simple unitary test code
MR927:Nr rrc configuration fr2
- introduces some bug fixes for FR2 that might also have an impact on FR1.
