A system and a method are disclosed to manage beams in a Multicast and Broadcast Services (MBS) wireless communication network. A first device receives a Physical Downlink Control Channel (PDCCH) and a Physical Downlink Shared Channel (PDSCH) for MBS communications in a Common Frequency Resource (CFR). The first device also receives a configuration sent by the second device that is for a MBS Beam Failure Detection Reference Signal (BFD-RS). The first device may then detect a MBS Beam Failure Incident (BFI) of a first MBS beam using the MBS BFD-RS configuration. In response to detecting the BFI, the first device may autonomously connect to a second MBS beam. Alternatively, the first device may communicate the BFI to the second device in order to recover a MBS beam. In one embodiment, the first device is a User Equipment (UE), and the second device is a Next Generation NodeB (gNB).
