- Most DL code is reused for Ul also to reduce code duplication
- Common CPE calculation function is used for error estimation
- Common slot processing function is used for inter/extrapolation
- Removed old implementation dedicated to UL
- updated return function value to -1
- removed static variable for dmrs symbol selection for channel
- Updated sin cos quadrant check conditions
- removed casting from PTRS slope and related calculations
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
- fixed channel compensation by choosing most recent DMRS symbol ina
slot
- Removed code to find nearest DMRS symbol for channle compensation
- Updated TBS calculation in DLSIM
- Added debug prints in PTRS CPE estimation for DMRS symbol

Above commit changed the TUN interface configuration to use program "ip"
only. This commit changes the CI script parsing correspondingly: the
pipeline will recognize the attempt to bring up the interface of the
first UE.
- Added PTRS extraction and estimation for DL
- Added processing for whole slot wrt PTRS estimates
- DLSIM is updated to used -T flag to enable PTRS
- DMRS compensated signal is further compensated with PTRS estimation

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
- Added PTRS variables in transport UE header file
- Added DMRS inline symbol check function in refsig.h
- Added PTRS estimation and other related structures in defs_nr_UE.h file
- PTRSPortIndex, PTRSTimeDensity, PTRSFreqDensity, PTRSReOffset, nEpreRatioOfPDSCHToPTRS
- mcs_table : to calculate MCS table in MAC layer and pass tp PHY
- pduBitmap : same as used in DL FAPI interface, to enable or disable PTRS processing
- Added a function to add PTRS values in RRC context.
- This function can be used to overwrite the PTRS values also.
- When RRC config file contains PTRS values then this function can be used
respectively in RRC context.

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
