Abstract
Techniques are provided herein to optimize up-link transmission power from a wireless terminal to a base transceiver station in a multicarrier system. A pathloss between the wireless terminal and the base transceiver station is determined. A determination is made if the pathloss is less than or larger than a predetermined value. One or more sub-carriers are assigned to the wireless terminal based on whether the pathloss between the wireless terminal and the base transceiver station is less than or larger than the predetermined value. A power cap command signal is sent from the base transceiver station to the wireless terminal for limiting a maximum allowable power transmitted by the wireless terminal to a predetermined level based on proximity of the one or more sub-carriers to an edge of a frequency band used for up-link transmissions made by the wireless terminal.
