Abstract
A method of OFDMA subcarrier allocation for stations in a wireless network includes determining a total downlink buffered traffic load for downlink traffic from a gateway device to the stations, and receiving a total uplink buffered traffic load for uplink traffic from the stations to the gateway device. The method further includes determining a first ratio of total downlink buffered traffic load for each station in relation to total downlink buffered traffic load for all stations, determining a second ratio of total uplink buffered traffic load for each station in relation to total uplink buffered traffic load for all stations, performing OFDMA subcarrier allocation for the downlink traffic by assigning available channel bandwidth proportional to the first ratio for each station, and performing OFDMA subcarrier allocation for the uplink traffic by assigning available channel bandwidth proportional to the second ratio for each station.
