Method of transmitting multicast broadcast service

摘要

A method of a base station transmitting Multicast Broadcast Service (hereinafter referred to as MBS) includes transmitting MBS configuration information, including information about an MBS region which is a resource region to which MBS-related information is allocated and information about an MBS MAP, to a terminal and transmitting MBS data to the terminal through the MBS region. The information about the MBS region includes location information and a transmission parameter of the MBS region. The MBS MAP includes an MBS configuration information change indication which indicates whether the MBS configuration information is expected to change from first MBS configuration information to second MBS configuration information. MBS is effectively and persistently managed in a mobile wireless communication system supporting MBS.

1. A method of transmitting Multicast Broadcast Service (hereinafter referred to as MBS) by a base station, the method comprising:
transmitting, to a terminal, information regarding an MBS region assigned to MBS-related information; transmitting MBS configuration information including the MBS MAP related information to the terminal; transmitting an MBS MAP to the terminal on the basis of the MBS configuration information, wherein the MBS MAP includes MBS information and a control information change indication indicating whether control information included in a secondary superframe header (S-SFH) is to be changed in this MBS Scheduling Interval (MSI); and transmitting MBS data to the terminal through the MBS region to the terminal, wherein a time offset at which the changed control information is to be received is determined based on the MBS MAP.
