Method and apparatus for prediction of a connection identifier in a downlink burst

A method of processing a downlink frame within a Medium Access Control (MAC) layer processor of a mobile station in a wireless communication system, the downlink frame comprising one or more downlink bursts, each of the one or more downlink bursts comprising a plurality of MAC layer protocol data units (MPDUs), each MPDU including a connection identifier (CID), wherein the CID is a number, the method comprising the steps of:

• processing one of the plurality of MPDUs to recover the CID thereof;
• determining whether to process a next one of the plurality of MPDUs of one of the one or more downlink bursts or whether to cease processing of the downlink burst in response to the CID of the one of the plurality of MPDUs being less than or equal to the predetermined CID value;
• and
• providing information to a physical layer processor to not submit any more of the plurality of MPDUs to the MAC layer processor in response to the determining step determining to cease processing of the plurality of MPDUs.

An apparatus for processing a downlink frame comprising one or more downlink bursts, each of the one or more downlink bursts comprising a plurality of MAC layer protocol data units (MPDUs), the apparatus comprising:

• receiver circuitry receiving radio frequency (RF) signals and demodulating the RF signals to recover the downlink frame;
• a physical layer processor coupled to the receiver circuitry and processing the downlink frame to recover the plurality of MPDUs therefrom, each of the plurality of MPDUs including a connection identifier (CID), wherein the CID is a number;
• and
• a MAC layer processor coupled to the physical layer processor and receiving one of the plurality of MPDUs therefrom, the MAC layer processor processing the one of the plurality of MPDUs to recover the CID thereof and determining whether to process a next one of the plurality of MPDUs of one of the one or more downlink bursts or whether to cease processing of the downlink burst in response to the relationship between the CID of the one of the plurality of MPDUs and the predetermined CID value being such that the CID of the one of the plurality of MPDUs is greater than the predetermined CID value.
