Abstract
Methods, systems, and arrangements enable balanced base station transmitter output power levels with respect to a receiving mobile station in a macro-diversity communication by adjusting a base station transmitter output power level responsive to power control command(s) sent by the mobile station and the (current) transmitter output power level of the base station. In a fixed adjustment step embodiment, power level convergence is enabled by adjusting the transmitter output power level of a given base station by a greater amount (e.g., than the nominal amount) when a power control command orders a power adjustment of the transmitter output power level towards a reference level and by adjusting the transmitter output power level by a lesser amount when a power control command orders a power adjustment of the is transmitter output power level away from the reference level. A continuous adjustment step embodiment is also disclosed.
