Method and system for managing configuration and control information of MBS services in wireless network

A method performed by a base station in a wireless communication system, the method comprising:

• transmitting a system information block including configuration information on a control message for multicast broadcast service (MBS);
• transmitting the control message based on the configuration information and a specific radio network temporary identifier (RNTI) for the MBS, the control message including control information on the MBS;
• and
• transmitting data associated with the MBS based on the control information,
• wherein a modification period associated with the control message is configured for the MBS, and
• wherein, in case that the MBS is served on a secondary cell (SCell), the MBS is not served on a primary cell (PCell).

A terminal in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• a controller configured to:
• receive, from a base station via the transceiver, a system information block including configuration information on a control message for multicast broadcast service (MBS),
• receive, from the base station via the transceiver, the control message based on the configuration information and a specific radio network temporary identifier (RNTI) for the MBS, the control message including control information on the MBS, and
• receive, from the base station via the transceiver, data associated with the MBS based on the control information,
• wherein a modification period associated with the control message is configured for the MBS, and
• wherein, in case that the MBS is served on a secondary cell (SCell), the MBS is not served on a primary cell (PCell).

A base station in a wireless communication system, the base station comprising:

• broadcast, via the transceiver, data associated with the MBS based on the control information,
• wherein a modification period associated with the control message is configured for the MBS, and
