1. A method for Multicast and Broadcast Service (MBS) switching and continuity in a 5th Generation (5G) wireless network, wherein the method comprises:
establishing, by a gNodeB, a MBS session with a user equipment (UE);
providing, by the gNodeB, at least one MBS to the UE during the MBS session;
detecting, by the gNodeB, that the at least one MBS is going to get suspended or deactivated based on signal strength and channel quality reaching a configured threshold; and
sending, by the gNodeB, an indication to the UE indicating the at least one MBS going to get suspended or deactivated prior to suspension or deactivation of the at least one MBS at the UE,
wherein signal strength and channel quality are measured on a Physical Downlink Shared Channel (PDSCH) carrying MBS, and
wherein the channel quality is determined by a channel quality indicator (CQI) parameter that is periodically measured by the UE and provided by the UE to the 5G wireless network.
