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 MR970 : uci gnb mac functions file - Moved gNB MAC UCI related functions in a new file MR972 : Bugfix nr rate matching assertion - Fixes the assertion happening in rate matching of pdsch during iperf test. MR975 : File openning in rrc_gNB_internal - Only allow file opening in rrc_gNB-internal.c in phytest mode MR977 : NR UE DCI sanity checks and fixes These changes resolve a few stability issues and errors in NR UE - Added sanity check for pucch_resource_indicator received in DL DCI, which resolves SEGV in select_pucch_resource() and check_pucch_format() - Additional sanity checks included to catch false or erroneous DCI received - Wrong MCS table calculation and error in accessing ul_config_request at UE resolved
