- Phy config update and Sidelink frame parameters initialisation - PSBCH scheduler to trigger TX PSBCH/RX PSBCH actions - Sidelink indication with rx ind to trigger send SL-MIB to MAC - Enable Scope for PSBCH use -d or --dqt - Enable system testing of PSBCH for example using RFSIMULATOR: - UE1 is a SYNCRONISATION SOURCE UE which transmits PSBCH started using command - sudo ./nr-uesoftmodem --sl-mode 2 --sync-ref 4 --rfsim --rfsimulator.serveraddr server - UE2 syncs onto UE1 during sidelink search, gets the timing and continues to receive PSBCH started using command - sudo ./nr-uesoftmodem --sl-mode 2 --rfsim --rfsimulator.serveraddr 127.0.0.1 - In the default use case 2 Sidelink SSBs sent over 16 frames. - In case SL-SSB configuration needs to be changed use -O option in the above command like -O ../../../targets/PROJECTS/NR-SIDELINK/CONF/sidelink_preconfig_1txpool.conf
