Abstract
Techniques for making channel assignments to reduce interference and increase capacity of wireless networks are described. In an implementation, a set of OFDMA subcarriers available for assignment is divided into a plurality of subsets of subcarriers that include at least a first subset for relatively strong signals within a cell, a second subset for relatively weak signals within the cell, and a third subset for signals within the cell that correspond to stations used by preferred users. Signals are received from a plurality of other stations, and relative signal strengths of the signals are determined based on a comparison between the signals. Each station is assigned a transmit subchannel that is formed for a predetermined period of time by one of the plurality of subsets of subcarriers, the transmit subchannel assigned based on a relative signal strength of a signal received from station.
