Abstract:
A method for controlling the transmission power of communication signals transmitted by a base station, the method comprising the steps of:a) at said base station, receiving a power control command from said user station;b) providing said power control command to a base station controller;c) providing from said base station controller to said base station a power adjustment command in accordance with said power control command, wherein said steps of providing said power control command to said base station controller and providing said power adjustment command to said base station in response thereto results in a response delay;d) transmitting from said base station a current communication signal at a transmit power level based on said power adjustment command;e) at said user station, receiving said current communication signal;f) at said user station, determining a received power level of said current communication signal;g) at said user station, adjusting a power level threshold based on a predetermined number of power control messages previously transmitted by said user station to said base station wherein said predetermined number is determined in accordance with said response delay;h) at said user station, comparing the adjusted power level threshold to said received power level of said current communication signal;i) at said user station, transmitting a current power control message based on said step of comparing; andj) at said base station, transmitting a new communication signal at an adjusted power level in accordance with said current power control message.
