The invention discloses a method, a system and apparatus for providing modulation and coding mode used by multicast service macro diversity. In this method, a message containing relevant information of modulation and coding mode(s) used by an MBS zone is sent in the MBS zone at first; the MS receives the message, analyzes other messages in the MBS zone according to the relevant information of the modulation and coding mode(s) contained in this message, and receives MBS service data according to the analyzed result upon other messages in the MBS zone. The invention resolves the problem that an entity is required to uniformly manage the coding and modulation mode definition of each cell in the prior art, as well as the problem that the DCD count in the DL-MAP message has to be continuously tracked in the prior art. |
