A wireless communication network is provided. The network comprising a plurality of base stations capable of wireless communication with a plurality of subscriber stations within a coverage area of the network. At least one of the plurality of base stations comprises a transmitter configured to transmit a downlink frame. The downlink frame comprising a first Enhanced Multicast Broadcast Service (E-MBS) MAP. The first E-MBS MAP comprises a field with an indicator to indicate a next E-MBS MAP to be decoded by a subscriber station. The subscriber station, upon decoding the first E-MBS MAP, refrains from decoding subsequent E-MBS MAPS that precede the next E-MBS MAP to be decoded by the subscriber station in accordance with the indicator.
