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
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 commit 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.)
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.
