Methods and apparatus to set mrb configuration for ue to receive mbs multicast in rrc inactive state

A method comprising:

• receiving, by a network entity, a joining request for a multicast session from a user equipment (UE) in a wireless network;
• transmitting, by a network entity of a wireless network, a multicast radio bearer (MRB) configuration to the UE for a multicast service preparing for a multicast reception in a radio resource control (RRC) INACTIVE state for the UE;
• transmitting multicast data for the multicast service to the UE in the RRC INACTIVE state;
• and
• updating multicast traffic channel (MTCH) information for the multicast service based on one or more preconfigured conditions.

A user equipment (UE), comprising:

• a transceiver that transmits and receives radio frequency (RF) signal in a wireless network;
• a multicast management module that joins a multicast session in the wireless network;
• a configuration module that receives a multicast radio bearer (MRB) configuration for a multicast service from the wireless network;
• an MRB module that establishes a MRB for reception of the multicast service in a radio resource control (RRC) INACTIVE state based on the MRB configuration;
• and
• a multicast control module that receives data transmissions of the multicast service from the wireless network with the established MRB in the RRC INACTIVE state.
