MR #1136 : CI: Migration of the physical-simulators to OpenShift
-- switch to a parallel pod deployment on the OpenShift Cluster
-- Huge gain in time : 1h30m down to 25 minutes
MR #1134 : Docker improvements 2021 april
-- updated the LTE-UE image generation.
* Proper configuration file in nfapi case
* Proper entrypoint
MR #1131 : Removing deprecated dl and ul_bwp_dedicated in config request at UE
MR #1091 : Ue pdsch pusch parallel
-- The UE code for now is unfit to process more than 1 slot in parallel.
This is why the PUCCH signal is not transmitted most of the time.
Hence, the following changes are made:
* Process only one slot at a time. Previously it was 2 slots in parallel.
* Now we do parallelization with the slot i.e., PUSCH and PDSCH are processed in parallel.
* Option for the UE to go back to sync mode instead of stopping if it loses sync with gNB. Command line parameter --non-stop enables it.
* New feature: Included a mechanism to detect false DCIs.
MR #1147 : benetel conf files fix
MR !1079 / MR !1108:
1. Read slots from config file and schedules all slots *except* for slots 0 and 10. This is not a problem, since currently we cannot allocate more than six HARQ feedbacks in a slot, but we might have up to 7 with current configuration
2. phytest mode is configurable. From `nr-softmodem -h`:
-m: Set the downlink MCS for PHYTEST mode
-t: Set the uplink MCS for PHYTEST mode
-M: Set the downlink banwdwidth (in PRBs) for PHYTEST mode
-T: Set the uplink banwdwidth (in PRBs) for PHYTEST mode
-D: Bitmap for DLSCH slots (slot 0 starts at LSB)
-U: Bitmap for ULSCH slots (slot 0 starts at LSB)
3. Scheduler prints more information: UE PHR, PUCCH SNR, PUSCH SNR, RSSI
4. The scheduler learned to scheduler DLSCH/ULSCH in mixed slots (if the time domain allocation matches the mixed slot)
5. The scheduler expects
* PDSCH Time Domain allocation index 0 to be the DL slot allocation
* PDSCH TDA index 1 for Mixed DL slot
* PUSCH TDA index 0 for UL slot
* PUSCH TDA index 1 for Mixed UL slot
* PUSCH TDA index 2 for Msg.3
6. Some more cleanup, e.g., separate PDSCH/PUSCH data structures into "semi-static" data (e.g., TDA allocation to use, since it changes seldomly) and "dynamic" data (e.g., RB allocation per slot, which changes every slot)

MR !1102 : nr rlc: bugfix: fix NACK with range
We do some sanity checks for incoming rlc control packets. One of them is to check that so_start is not > so_end when present.
But when 'range' is present and bigger than 1 it means that so_start refers to one PDU and so_end to another one. So we may well have so_start > so_end.
This MR fixes that and reorganizes a bit the code to do the check before processing and rejecting the PDU if the values are not correct. (Before this commit we were NACKing the whole PDUs if so_start > so_end.)
MR !1096 : build_oai: Add --sanitize-address option

MR !1092: Nr pdcp nia2 integrity
This code has not been tested with a COTS UE. We need SRB1/2 (so we need SA) to test.
The activation of security and integrity for SRB1 will need more code (new functions) because it happens after some time, not at creation time of the PDCP entity and there is no way to do this with current code.

-Simplification:
remove rfsim flags that have been made for convergence with replay function in usrp driver, but this is useless as they changed their code
-Fix a bug in ubuntu 20.04 (now the code is ready in whole OAI)
MR1056 : Bugfix: NR BSR calculation
Fixes a bug in the scheduler for BSR calculation.
Before, we might wrongly track the BSR of a UE and not schedule it anymore although it has data.
Should be fixed now and improve UL throughput.

MR1030 : CI RHEL container update
-CI adaptation to build the shared and target images on asterix and obelix Python framework
MR1023 : ci ue parallel
-Enables OAI UE parallelization in CI tests (where applicable)
If we NACK without SOstart/SOend then the other end of the RLC channel will consider all the bytes as NACKed and will have to resend them all.
If another status is then reported before all the bytes are sent, and because we don't use SOstart/SOend this status will NACK all the bytes again, then all the bytes are to be sent again.
And the cycle repeats. It will end with a max retx reached (which triggers RLF, Radio Link Failure).
MR1010 : NR UE: Fix for error message - no active DLSCH
- Fixes for the following error message at UE: [PHY] [UE][FATAL] nr_slot_rx 1: no active DLSCH
MR994 : Cleanup softmodem main

MR992: Fix data transmission in "do-ra" mode
- UL and DL Traffic works now in do-ra mode, but there are still some PUCCH issues remaining. These issues are harming the acknowledgement of DL packets, and thus leading to unnecessary retransmissions.
The relevant warnings at UE are:
`PUCCH Invalid pucch resource indicator: at line 1082 in function select_pucch_resource of file openair1/SCHED_NR_UE/pucch_uci_ue_nr.c`
and
`PUCCH Error for number of bits for acknowledgment : at line 909 in function get_downlink_ack of file openair1/SCHED_NR_UE/pucch_uci_ue_nr.c`
Note: UE needs rbconfig.raw and reconfig.raw files from the *currently* running gNB, as the C-RNTI is random and different for each run.
MR969: Develop oriecpriupdates
Makes IF5 functionality compatible with ECPRI user-plane.
Control-plane functionality for supporting third-party RRUs : provides an interface converting OAI-native RF parameters, a subset of LTE framing parameters, and RF streaming activation/deactivation to a wrapper (libthirdparty_transpro.so) which uses the proprietary interface of the RRU.
This branch was tested with a commercial eCPRI RRU from AW2S.
MR980: Nr ul scheduler basis
- cleanup of UL scheduler, and add interface preprocessor-postprocessor (in `NR_UE_sched_ctrl_t`)
- Postprocessor can (almost) handle multiple UEs. Preprocessor will follow soon (proportional fair scheduler)
- Preprocessor for phytest (always schedule 50 RBs due to OAI UE limitations) and real UE (as many resources as possible)
- Internal structures have been updated: the `UL_tti_req` structure became an array (as `UL_tti_req_ahead`) so that we can schedule in advance and mark resources as used. Before, we would keep the corresponding nfapi message structure per UE, which could get messy when we have many UEs.
There are no functional changes (UL/DL performance is the same).
MR987: Nr phy mac if multi ue
- Handles multiple UEs in `NR_IF_interface.c`
- Some minor clean up
MR979: Pusch decoder threads parameter
- Added a config file parameter for specifying the number of threads to be used for PUSCH decoding.
MR982: nr pdcp: use pdcp config
-There was a problem with SN size. It was hardcoded to 12 bits (so max sn = 4095) but we configure the UE with 18 bits.
Get the correct value from pdcp_Config.
- Store also discard_timer and t_reordering that will be used later by a proper NR PDCP layer
MR984: NR FR2 SSB
- several fixes mainly concerning FR2 synchronization and RA both at gNB and UE
- SSB RRC signaling for FR2
- Coreset RRC for FR2
- SSB detection in FR2 for SSB index > 15
- Adjust sync function issue
- Fix for scheduling of MSG2 (issue with sl_ahead)

MR962: Remove x2 gnb hardcoding
- Removes hardcoding of some x2 configuration parameters used in ENDC setup request message at gNB side
MR949: rlc v2: change time keeping
- RLC has timers. We need to keep track of time.
We introduce rlc_tick() and call it in eNB_dlsch_ulsch_scheduler, which is called every subframe, both in FDD and TDD.
MR945 : nr prach fr2
- Introduction of the PRACH frontend for FR2 (120kHz SCS, 32 and 66 PRB).
- Tested with nr_prachsim and testcases added to test_case_list.xml also included some fixes for FR1,
when prach occasion > 0 (small difference in Ncp)
MR950 : DL and UL PTRS for 5G NR
MR971 : Correct NDI + Minor MAC subPDU handling improvements
Fixes the issue : Ping in develop was unusually high (70+ms). The issue was that TA was scheduled in the second slot (of the two we currently schedule), but NDI was toggled for the first one.
Other improvements:
- Correctly put padding MAC subPDU
- Only use subPDU DLSCH long header if length >= 256B
- Calculate TBS in DL pre-processor considering header and TA CE overhead.
- Improve some of the logging (LOG_D)
- re-enable TA

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.

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:

- 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.
