摘要： A method for setting a multicast and broadcast service (MBS) of a broadband wireless access system includes: previously receiving and storing the information on the MBS setting from a MBS server by a radio access station; and broadcasting the information on the MBS setting stored in the PSS, which exists in the service area of the radio access station, by the radio access station. In the step of broadcasting the information on the MBS setting, a preset pilot tone, uplink/downlink information, or the sub-carriers unused in bandwidth of the system are used for broadcasting the information.
