Abstract
Provided are a method and apparatus for security multicast and broadcast service (MBS) communication in a wireless communication system. An operating method of a terminal in a wireless communication system includes receiving configuration information to be applied to MBS data from a base station, and receiving the MBS data based on the configuration information, wherein the configuration information is for configuring an initial value of a state variable corresponding to the MBS data.
Claims14
A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, from a base station, configuration information for a multicast broadcast service (MBS), wherein the configuration information for the MBS includes an initial value of an RX_DELIV;
- and
- applying the initial value of the RX_DELIV to the RX_DELIV for a radio bearer for the MBS,
- wherein the RX_DELIV is a packet data convergence protocol (PDCP) state variable indicating a count value of a first packet not delivered to an upper layer.
A user equipment (UE) for use in a wireless communication system, the UE comprising:
- a transceiver;
- and
- at least one processor coupled with the transceiver and configured to:
- receive, from a base station, configuration information for a multicast broadcast service (MBS), wherein the configuration information for the MBS includes an initial value of an RX_DELIV;
- and
- apply the initial value of the RX_DELIV to the RX_DELIV for a radio bearer for the MBS,
- wherein the RX_DELIV is a packet data convergence protocol (PDCP) state variable indicating a count value of a first packet not delivered to an upper layer.
A method performed by a base station in a wireless communication system, the method comprising:
- transmitting, to a user equipment (UE), configuration information for a multicast broadcast service (MBS), wherein the configuration information for the MBS includes an initial value of an RX_DELIV,
- wherein the transmission of the initial value of the RX_DELIV causes the UE to apply the initial value of the RX_DELIV to the RX_DELIV for a radio bearer for the MBS, and
- wherein the RX_DELIV is a packet data convergence protocol (PDCP) state variable indicating a count value of a first packet not delivered to an upper layer.
A base station for use in a wireless communication system, the base station comprising:
- a transceiver;
- and
- at least one processor coupled with the transceiver and configured to transmit, to a user equipment (UE), configuration information for a multicast broadcast service (MBS), wherein the configuration information for the MBS includes an initial value of an RX_DELIV,
- wherein the transmission of the initial value of the RX_DELIV causes the UE to apply the initial value of the RX_DELIV to the RX_DELIV for a radio bearer for the MBS, and
- wherein the RX_DELIV is a packet data convergence protocol (PDCP) state variable indicating a count value of a first packet not delivered to an upper layer.
