Abstract:
1. A method comprising: receiving at a first station a signal from a second station; measuring, at the first station, a signal strength of the received signal; determining that the signal strength is relatively weak compared to other signals received at the first station from one or more additional stations; dividing a set of OFDMA subcarriers available for assignment into at least a first subset of subcarriers for relatively weak signals within a first cell, a second subset of subcarriers for relatively strong signals within the first cell, and a third subset of subcarriers for signals within the first cell that correspond to stations used by preferred users; and assigning to the second station a transmit subchannel formed from the first subset of subcarriers for a predetermined period of time, the transmit subchannel assigned to the second station based on the determination that the signal strength of the received signal is relatively weak.
