Abstract
A method for communication includes accepting a request from a transmitter to transmit data to a receiver in a multiple-access communication system that uses multiple subcarriers. A maximum number of the subcarriers on which the transmitter may transmit the data simultaneously without violating a predetermined signal power criterion is calculated. The transmitter is allocated a time-frequency allocation containing the maximum number of the subcarriers. The data is transmitted from the transmitter to the receiver using the allocated time-frequency allocation.
