Abstract (en)
[origin: WO9953630A1] A method adjusts the output power offset between a first signal and a second signal transmitted from a base station to a remote station in a communication system including at least one base station and at least one remote station. The first signal may be a power control command for controlling the power of signals transmitted uplink from the remote station to the base station, and the second signal may be downlink information. A determination is made whether the remote station is in macrodiversity, i.e., receiving substantially the same signal simultaneously from more than one base station, and the output power offset between the first and second signals is adjusted based on this determination. The output power offset may be set at a first level if the remote station is in macrodiversity and at a second level if the remote station is not in macrodiversity. Alternately, whether or not the remote station is in macrodiversity, the output power offset may be adjusted based on a required quality calculated from a determined characteristic of a signal.
