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.
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!
