1. A wireless transmit/receive unit (WTRU) comprising a processor and memory configured to:
receive Multicast/Broadcast Services (MBS) configuration information, the MBS configuration information comprising first MBS discontinuous reception (DRX) configuration information associated with a first group radio network temporary identifier (G-RNTI), second MBS DRX configuration information associated with a second G-RNTI, configuration information associated with at least a first MBS radio bearer (MRB), and an indication of one or more logical channels IDs (LCIDs) associated with the first MRB, wherein the configuration information associated with the first MRB comprises an initial value for a variable for determining packet data convergence protocol (PDCP) packets to be discarded, the first MBS DRX configuration information indicates values for a first MBS DRX on duration timer, a first MBS DRX slot offset, a first MBS DRX inactivity timer, a first MBS DRX cycle length, a first MBS DRX cycle start offset, a first MBS DRX downlink (DL) retransmission timer, and a first MBS DRX hybrid automatic repeat request (HARQ) round trip time (RTT) timer, and the second MBS DRX configuration information indicates values for a second MBS DRX on duration timer, a second MBS DRX slot offset, a second MBS DRX inactivity timer, a second MBS DRX cycle length, a second MBS DRX cycle start offset, a second MBS DRX DL retransmission timer, and a second MBS DRX HARQ RTT timer;
monitor for a physical downlink control channel (PDCCH) transmission using the first G-RNTI during a first DRX active time associated with the first MBS DRX configuration information, wherein the first active time comprises a time when the first MBS DRX on duration timer, the first MBS DRX inactivity timer, or the first MBS DRX DL retransmission timer is running;
monitor for a PDCCH transmission using the second G-RNTI during a second DRX active time associated with the second MBS DRX configuration information, wherein the second active time comprises a time when the second MBS DRX on duration timer, the second MBS DRX inactivity timer, or the second MBS DRX DL retransmission timer is running;
receive at least one PDCCH transmission using at least one of the first G-RNTI or the second G-RNTI;
decode a transport block based on the at least PDCCH transmission;
determine at least one medium access control (MAC) protocol data unit (PDU) from the transport block;
discard first data from the at least one MAC PDU that is associated with a LCID that is not one of the indicated one or more LCIDs; and
determine, based on the variable for determining PDCP packets to be discarded, whether to discard second data corresponding to a PDCP PDU that is from the at least one MAC PDU and that is associated with a LCID that is one of the indicated one or more LCIDs.
