Abstract
The invention includes a method and apparatus for adjusting the transmit power of a base station. In one embodiment, the transmit power of a base station is adjusted using rate metrics. A method according to one embodiment includes adjusting a transmit power of a target base station based on a per-user rate metric associated with the target base station and at least one per-user rate metric associated with at least one other base station. The per-user rate metrics may be based on any base station metrics, such as average system throughput of the base station, aggregate cell capacity of the base station, and the like. The per-user rate metrics may be computed or estimated using feedback information from wireless user devices. In one embodiment, the transmit power of a base station is adjusted using other information, such as geographic distances between base station, signal strength measurements received at base stations from other base stations, and the like, as well as various combinations thereof. A method according to one embodiment includes obtaining non-feedback information and adjusting the transmit power of the base station using the non-feedback information.
