Patent ID: 7925268

Claim:
A method comprising: at a base transceiver station, determining a pathloss between a wireless terminal and the base transceiver station using forward and reverse power control schemes to determine the pathloss; determining if the pathloss is less than or greater than a predetermined value; assigning one or more sub-carriers of a frequency band used for up-link transmissions made by the wireless terminal based on whether the pathloss is less than or greater than the predetermined value, wherein assigning comprises assigning sub-carriers further away from an edge of the frequency band when the pathloss is less than the predetermined value and assigning sub-carriers closer to the edge of the frequency band when the pathloss is greater than the predetermined value; determining proximity of the one or more sub-carriers to the edge of the frequency band; assigning a power level to the one or more sub-carriers based on said proximity; sending a power cap command signal from the base transceiver station to the wireless terminal, wherein sending comprises sending the power cap command signal that is configured to limit a maximum allowable power transmitted by the wireless terminal to a predetermined level based on proximity of the one or more sub-carriers to the edge of the frequency band of the wireless terminal such that the power cap command signal limits the maximum allowable power to a higher maximum allowable power for sub-carriers that are away from the edge of the frequency band than for sub-carriers that are closer the edge of the frequency band.
