Patent ID: 8416675

Claim:
A method comprising: recording, by a base station, received signal strength information of a plurality of mobile stations of a wireless neighborhood; estimating, by the base station, a received signal strength of an upcoming uplink transmission from each of one or more mobile stations, of the plurality of mobile stations, that will be allocated uplink resources in an orthogonal frequency division multiple access (OFDMA) frame; determining, by the base station, a desired peak-to-average power ratio (PAPR) reduction for each of the one or more mobile stations for the OFDMA frame based at least in part on the estimated received signal strength; determining, by the base station, a tone reservation mode to implement at a first mobile station of the one or more mobile stations based at least in part on the desired PAPR reductions, the tone reservation mode to identify data tones, assigned to either the first mobile station or a second mobile station for communication with the base station in the OFDMA frame, that are simultaneously to be used by the first mobile station for transmitting a PAPR reduction sequence with a power below a power spectrum density constraint to avoid interference with data transmissions; and transmitting, by the base station to the first mobile station, the tone reservation mode to implement at the first mobile station.
