1. A method for receiving multicast broadcasting service (MBS) data by a mobile station, the method comprising:
- receiving, by the mobile station from a base station, information for receiving MBS data via at least one of a plurality of MBS streams including a base MBS stream and at least one enhanced MBS stream which are broadcast by the base station; and
selectively receiving, by the mobile station from the base station in a manner of broadcasting, the MBS data with a second quality via the at least one enhanced MBS stream in accordance with a resolution capability and a channel quality of the mobile station while receiving, by the mobile station from the base station in a manner of broadcasting, the MBS data with a first quality via the base MBS stream,wherein the base MBS stream carries the MBS data with the first quality and information on a location of the at least one enhanced MBS stream,wherein the at least one enhanced MBS stream carries the MBS data with the second quality, andwherein the mobile station adaptively transits among the plurality of MBS streams according to a current channel quality of the mobile station while receiving the MBS data, by detecting the at least one enhanced MBS stream using the information on the location of the at least one enhanced MBS stream in the base MBS stream.

Abstract
A method for adaptively receiving and providing a multicast broadcasting service (MBS) according to at least one of capability and a channel status of a mobile station (MS) is disclosed. In more detail, a base station provides the MBS to MSs using different layers according to the capabilities and/or the channel statuses of the MSs, and the MSs adaptively receive the MBS according to the respective capabilities and/or the channel statuses of the MSs.

9. A mobile station for receiving multicast broadcasting service (MBS) data in a wireless communication system, the mobile station comprising:
-
a receiver configured to receive radio frequency signals from a base station; and a processor configured to control the receiver to receive information for receiving MBS data via at least one of a plurality of MBS streams including one base MBS stream and at least one enhanced MBS stream which are broadcast by the base station, and to selectively receive, in a manner of broadcasting, the MBS data with a second quality via the at least one enhanced MBS stream in accordance with a resolution capability and a channel quality of the mobile station while adaptively receiving, in a manner of broadcasting, the MBS data with a first quality via the base MBS stream, wherein the base MBS stream carries the MBS data with the first quality and information on a location of the at least one enhanced MBS stream, wherein the at least one enhanced MBS stream carries the MBS data with the second quality, and wherein the processor adaptively transits among the plurality of MBS streams according to a current channel quality of the mobile station while receiving the MBS data, by detecting the at least one enhanced MBS stream using the information on the location of the at least one enhanced MBS stream in the base MBS stream.
