METHOD AND APPARATUS FOR RECOGNIZING MULTICAST AND BROADCAST SERVICE REGION IN BROADBAND WIRELESS COMMUNICATION SYSTEM

摘要

A method and an apparatus for recognizing a Multicast and Broadcast Service (MBS) region in a broadband wireless communication system are provided. In the method, whether a next MBS MAP message transmission point of a first frame and an MBS data burst transmission point indicated by MBS burst assignment information of a second frame match with each other in a third frame is determined. When matching with each other in the third frame, a control message including information for determining a starting point of an MBS region is generated. The generated control message is transmitted during one of the first and second frames.
