MR939 : Nr rlc am bugfix w44
- bugfix
MR948 : nr: rlc: hotfix - forgot to store frame and subfram
- minor bugfix
MR942 : Feature/make s1 mme port configurable
- This patch adds an optional "port" option to set another sctp port than 36412
MR959 : minor: remove a CPPCHECK error for NR RLC
- remove a CPPCHECK error (not a real error) for NR RLC
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
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.
MR902 Nr mac ssb ro ue idcc
- Construction of SSB-RO mapping table on the UE
- RO selection based on SSB index
- RACH preamble selection based on SSB index in a selected RO
- RA-RNTI calculation
MR928 nr: add MAC PDU traces for wireshark
- The T tracer macpdu2wireshark has been modified to handle the new traces. The usage is the same as for LTE.
MR929 RA fixes for NR UE
MR938 CI: Parse UE TUN interface correctly in S1 mode
- The TUN interface configuration is changed to use program "ip" only.
- The CI script parsing is changed accordingly: the pipeline will recognize the attempt to bring up the interface of the first UE.
MR933 nr rlc: bugfix
- ret.next was not set in a particular case
Integration 2020 wk44
MR923 : Fixes tun
TUN-interface related changes
MR925 : bugfix: fix frequencies in nr_bandtable
The array nr_bandtable has then been reviewed fully and all the values that were wrong have been changed. The check of correctness was done using the website https://www.sqimway.com/nr_band.php
MR931 : Finalize oaicn integration (CI)
In addition, the "known unstable scenarios" are highlighted in the CI HTML reports.
MR917 : NR CSI reporting
This is a new feature
Integration 2020 wk42 (2)
MR921 : Hotfix for DL DCI issue in UE
Fixing a bug from last MR.
Fix in nr_dlsim that prevents reporting false 'PDSCH ok' message
MR915 : Fix to avoid RRC->X2AP ticking every msec when x2ap task is not enabled
The aim of itti RRC_SUBFRAME_PROCESS message (MAC->RRC) is to trigger an itti X2AP_SUBFRAME_PROCESS message (RRC->X2AP)
This change avoids creating RRC_SUBFRAME_PROCESS message if x2ap task is not enabled
Integration 2020 wk40 comprises the following udpates:
MR893 ULSCH decode mthread:
- Enabled parallelization of ULSCH segments decoding, deinterleaving and rx rate matching.
MR896 Nsa remove band hardcodings:
- A missing commit from wk39, just a log change
MR901 NR UE DCI improvements:
- Handling of DCI formats 0_0 and 0_1, including removing hard-coding and scheduling PUSCH with DCI parameters
- Blind decoding of DCIs based on size and format indicator
- Fix for segmentation fault during ULSCH encoding
MR895 support of RA procedure by implementing Msg3 on UE
MR908 NR DL scheduler improvements:
Preliminary work on the DL scheduler
- cleanup of DL scheduler, add interface preprocessor-postprocessor (`NR_UE_sched_ctrl_t`)
- postprocessor can handle multiple UEs. Preprocessor will follow soon (proportional fair scheduler)
- No MAC UE Context creation before end of RA (Msg 3)
These updates do not change anything performance wise (no additional scheduled slots, etc).
This MR also reduces gNB log.
MR 896 : Nsa remove band hardcodings
Removes hardcodings of EUTRA and NR bands in UE_Capability_Enquiry and NR_UE Capability_Enquiry messages, providing them from the eNB config file and gNB over X2 respectively. Moreover, the SSB Absolute frequency of the gNB is now provided by the eNB configuration file (instead of being hardcoded at rrc_eNB.c)
MR903 : pusch ta update
Update of PUSCH Timing advance
MR 900 : improve x2/rrc for ENDC
This MR introduces several enhancements in X2AP and RRC to deal with ENDC.
The main goal is to deal with UE's on/off and with various errors.
Includes :
- DC prep and DC overall X2 timers
- X2 messages for UE release and DC timers' timeout
