Abstract:
1. A method of scheduling a downlink subframe for transmission comprising: assigning frequency and time dimensions of downlink bursts to each of a plurality of subscriber stations based on one or more individual channel characteristics and one or more individual data requirements associated with the subscriber stations, wherein channel capacities for each of a plurality of subchannels between the subscriber stations and a base station are generated from the channel characteristics including from one or more of channel estimates generated by the base station, channel feedback or performance feedback being generated by one or more of the subscriber stations, generating a subchannel capacities matrix that includes a subchannel capacity for each subchannel with each of the subscriber stations based on the channel characteristics for each subscriber station; and generating a scheduling metrics matrix comprising scheduling metrics, the scheduling metrics matrix having a column for each subscriber station and a row for each subchannel, and wherein the assigning comprises: selecting either a row or a column of the scheduling metrics matrix having a maximal difference between the two maximal elements of either a row or a column; selecting a maximal element of the selected row or column, the maximal element corresponding to one of the subscriber stations and one of the subchannels; and assigning capacity of the corresponding subchannel to the corresponding subscriber station.
