Abstract:
1. A method for wireless communication, comprising: transmitting, from a base station, a frame that comprises a downlink subframe and an uplink subframe, wherein the downlink subframe comprises a single description segment, a downlink map, and one or more data burst segments, wherein the single description segment is separate from the downlink map and appears in a beginning portion of the downlink subframe and in a subchannel location before the downlink map, the single description segment including one or more unique subscriber identifiers to identify one or more corresponding subscriber stations to which at least a portion of data placed in the downlink subframe is addressed, wherein the downlink map comprises information indicative of one or more data burst segment locations within the downlink subframe; causing a subscriber station in communication with the base station to receive and decode the single description segment in the downlink subframe before decoding the downlink map and to determine whether the receiving subscriber station is identified by the single description segment as one of the subscriber stations to which at least one portion of the data placed in the downlink subframe is addressed; when the receiving subscriber station is not identified in the single description segment, causing the receiving subscriber station to turn off a receiver in the receiving subscriber station for a remainder of the frame without further receiving and decoding the remainder of the frame; and when the receiving subscriber station is identified in the single description segment, causing the receiving subscriber station to continue receiving and decoding a remaining part of the frame to recover data in the downlink subframe that is addressed to the receiving subscriber station.
