Title of Invention	METHODS AND APPARATUS FOR CONTROLLING A BASE STATION'S TRANSMISSION POWER
Abstract	A base station receives loading information indicative of the loading of other base stations and determines a downlink transmission power budget as a function of the received loading factor information. The base station may decrease/increase a current power budget dedicated to downlink traffic channel segments in response to detecting an increase/decrease in loading at an adjacent base station. Thus, base stations operate in a cooperative manner reducing power output, in at least some cases, where loading at a neighboring base station increases thereby reducing the interference to the base station with the increased load. A base station can consider possible alternative transmission power levels, estimated levels of interference, and/or possible alternative data rates in making trade-off decisions regarding downlink power budget.

METHODS AND APPARATUS FOR CONTROLLING A BASE STATION'S TRANSMISSION POWER

Abstract

A base station receives loading information indicative of the loading of other base stations and determines a downlink transmission power budget as a function of the received loading factor information. The base station may decrease/increase a current power budget dedicated to downlink traffic channel segments in response to detecting an increase/decrease in loading at an adjacent base station. Thus, base stations operate in a cooperative manner reducing power output, in at least some cases, where loading at a neighboring base station increases thereby reducing the interference to the base station with the increased load. A base station can consider possible alternative transmission power levels, estimated levels of interference, and/or possible alternative data rates in making trade-off decisions regarding downlink power budget.

Full Text	In a wirless communication system including a plurality of base stations with a least some of the base stations using the same resources, e.g., frequency spectrum, downlink transmission from one base station can interference with downlink transmissions of other e.g., adjacent base stations using the same frequency spectrum..............
