Method and apparatus for receiving multicast and broadcast service in a broadband wireless communication system

摘要

The present specification relates to a method in which, in a broadband wireless communication system, a mobile station operates to receive multicast and broadcast service (MBS) data in the event a base station supports at least one MBS zone, wherein said method comprises: a step of receiving a first control message including at least one piece of control information from the base station; extracting, from the received first control message, control information corresponding to the MBS zone to which the mobile station belongs; and a step of receiving a second control message including MBS data burst allocation information using the extracted control information, wherein said control information contains the MBS zone identification information and/or the resource allocation information of the second control message.

1. An operation method of a mobile station for receiving multicast and broadcast service (MBS) data when a base station supports at least one MBS zone in a broadband wireless communication system, the method comprising:
receiving a first control message including at least one control information from the base station; extracting control information corresponding to an MBS zone in which the mobile station is included from the received first Control message; and receiving a second control message including MBS data burst allocation information using the extracted control information, wherein the control information is an enhanced multicast and broadcast service (B-MBS) control header information element (IE), wherein the E-MBS control header IE includes resource allocation information of an E-MBS NAP, E-MBS zone identification information and an indicator indicating whether there exits another E-MBS control header IE additionally transmitted subsequent to the E-MBS control header IE and wherein if the indicator has a bit value of 1, the indicator indicates that the another E-MBS control header IE follows the E-MBS control header IE.
