Patent ID: 8031649

Claim:
A method for transmitting data comprising: obtaining a plurality of data units associated with identifiers, the identifiers including connection identifiers (CIDs) associated with one or more subscriber stations, each identifier associated with a particular subscriber station; arranging a first group of data units in ascending order by their associated identifiers; arranging a second group of data units in descending order by their associated identifiers; and transmitting the first group of the data units in a downlink burst to the one or more subscriber stations; transmitting the second group of the data units in a second downlink burst to the one or more subscriber stations; wherein both the first and second downlink bursts include a bit flag configured to indicate that data units of the first and second group of data units are arranged in a logical order according to the identifiers; wherein the logical order of the first group of data units allows a subscriber station to determine a first cutoff value for the first data units based on a highest value identifier associated with the subscriber station, and to determine a second cutoff value for the second data units based on a lowest value identifier associated with the subscriber station, the first and second cutoff values allowing the subscriber station to refrain from decoding data units when no more of the first group of data units are intended for the subscriber station.
