With the merge of fix_NR_DLUL_PF, gNB_dlsch_ulsch_scheduler() has no
nb_periods_per_frame variable. There are two changes here:
1) calculate this locally for initializing tdd_beam_association
2) do not pass it into schedule_nr_mib(). Further, use the following:
nb_periods_per_frame = slots_per_frame / slots_per_period
slots_per_frame / nb_periods_per_frame =
= slots_per_frame / (slots_per_frame / slots_per_period)
= slots_per_period
-MR !1052 : Nr fapi beamindex ssb ro
This branch completes RA procedure for FR2 and includes improvements for beam index communication through FAPI interface.
-fix_rb_corruption:
A memcpy() introduced to optimize for the case of no precoding corrupted RBs which are not allocated to PDSCH in the common txdataF array.
So instead, fall back to memcpy() for each PDSCH RB.
-benetel configuration files update

MR !1037: 5G NR DL MIMO
MR !1089: Fixes two issues that we encountered with the new Quectel modules (RM500Q-GL)
-make LTE RRC buffers large enough
-fix initial{D,U}LBWPlocationAndBandwidth in NR config file so that all accept it
In case of false positive PDSCH CRC check, a random MAC PDU is processed.
Currently pdu_len is unsigned 16 Bit, so we did break out of the processing loop only if we _exactly_ hit a residual pdu_len of 0, or we hit a LCID of DL_SCH_LCID_PADDING.
If we didn't hit either of these, pdu_len wrapped to a very positive value, and we continued processing the PDU even beyond its bounds!
This behavior was observed with SNR 1 dB and MCS 9.
So better make pdu_len signed and break out of the loop after processing at max. pdu_len Bytes!
MR !1071 : rohan_ulsim2RxFix
-Support added for 2RX antennas case in ulsim
-fixed indexing issue in gNB RX chain
MR !1086 : fix-nr-pdcp-timer
-The discard timer (set to infinity) is used by the PDCP layer to discard packets that were not transmitted to RLC after some time.
MR !995 : NR_MAC_TCI_UCI_GlobalEdge
TCI:
-Activation of PDSCH TCI states, Activation of PDCCH TCI state
-Construction of the codepoint, Updating nFAPI DCI1_1 (tci_field)
-SSB Beam switching on basis of CSI MeasReport(SSB RSRP)
-Added get_measured_rsrp and get_diff_rsrp API’s to get SSB RSRP’s.
UCI:
-Bit length calculation for the scheduled UCI Reporting for CSI-RS and SSB
-Extraction of received CSI Report (L1-RSRP) when according to the calculated bit lengths and processing it.
MR !1082 : NR_10MHz
-Support of 10MHz BW for 5G NR
MR !1013 : ptrs_rrc_config
-Remove hardcoding of DL and UL PTRS parameters at gNB and NR UE
