MR !1145 NR_FR2_initsync_fixes
-bug fixes that caused failure in PBCH detection after initial sync in FR2

MR !1100 NR_scheduling_request
-per-UE PUCCH F0 resource, CSI, Preamble 
-Scheduling Request 
-MAC scheduler fixes

MR !1150  rh_ci_phy_test_improve
-beautified HTML report for 5G NR phy test

MR !1113 hack-exit-gnb-when-no-enb-nsa
-Exit gNB if connection to eNB failed - to be modified if needed. We may want to try to connect over and over again until we succeed but the modifications to the code to get this behavior are complex
