Background During RAN4#93 meeting simulation assumptions for NR-U FRCs were agreed in [1]. Additionally during RAN4#94e meeting updated FRCs were agreed in [2]. Companies submitted for RAN4#94-e-bis SNR ssimulation results for NR-U FRCs and proposals for BS receiver requirements for NR-U. This WF collect agreements on BS Rx requirements for NR-U done during RAN4#94-e-bis meeting. [1] R4-1916162, WF on NR-U BS RF RX FRC, ZTE [2] R4-2002465, WF on NR-U FRCs, Nokia, Nokia Shanghai Bell
