5g multicast-broadcast services (mbs) multiplexing, reliability, and power savings

A wireless transmit/receive unit (WTRU), comprising a transceiver and one or more processors, configured to:

• receive a configuration for reception of a multicast-broadcast service (MBS) service, wherein the configuration indicates:
• a value for a variable to be processed at a Packet Data Convergence (PDCP) layer, and
• one or more logical channels associated with the MBS service;
• initialize, based on the value, the variable;
• receive a transport block comprising MBS traffic;
• decode the received transport block comprising the MBS traffic;
• and
• based on decoding the received transport block:
• discard, at a medium access control (MAC) layer, data not associated with the one or more logical channels associated with the MBS service, and
• process, at the PDCP layer and based on the initialized variable, data associated with the one or more logical channels associated with the MBS service.

A method for use in a wireless transmit/receive unit (WTRU), the method comprising:

• receiving a configuration for reception of a multicast-broadcast service (MBS) service, wherein the configuration indicates:
• a value for a variable to be processed at a Packet Data Convergence (PDCP) layer, and
• one or more logical channels associated with the MBS service;
• initializing, based on the value, the variable;
• receiving a transport block comprising MBS traffic;
• decoding the received transport block comprising the MBS traffic;
• and
• based on decoding the received transport block:
• discarding, at a medium access control (MAC) layer, data not associated with the one or more logical channels associated with the MBS service, and
• processing, at the PDCP layer and based on the initialized variable, data associated with the one or more logical channels associated with the MBS service.
