Abstract:
1. A method for improving power efficiency of subscriber stations in a wireless communication network, the wireless communication network comprising a base station and a plurality of subscriber stations, the base station communicating resource allocation information to the plurality of subscriber stations using at least one sub-Media Access Protocol (sub-MAP) message, each sub-MAP message of the at least one sub-MAP message comprising a plurality of information elements, each information element of the plurality of information elements comprising a Connection Identifier (CID), the CID uniquely identifying a subscriber station of the plurality of subscriber stations, the method comprising: splitting each CID into a first part and a second part based on pre-defined criteria to form a plurality of first parts and a plurality of second parts; generating an index, the index comprising a plurality of entries, wherein the plurality of entries in the index is constituted by one of the plurality of first parts and the plurality of second parts; transmitting the index to the plurality of subscriber stations by the base station; switching to a power-saving mode by one or more subscriber stations of the plurality of subscriber stations on absence of a match between each entry of the plurality of entries in the index and an equivalent part of CIDs associated with the one or more subscriber stations; and recombining each CID split by the base station, wherein each subscriber station of the plurality of subscriber stations recombines a split CID to determine the resource allocation information when the equivalent part of CID associated with the subscriber station matches an entry of the plurality of entries in the index.
