  • Reducing interference in cellular mobile communications networks
    Patent number: 6925303
    Abstract: In a cellular mobile communications network a mobile station is capable of receiving a downlink signal from each of a plurality of base stations and transmitting an uplink signal to the plurality of base stations through a wireless channel. A transmission property of the downlink signals from the plurality of base stations to the mobile station is measured, and decided, in dependence upon the measure of the transmission property, a preferred base station transmitting the downlink signal with a preferred transmission property among the plurality of the base stations. The mobile station includes, in the uplink signal, data indicating the preferred base station(s) for transmitting the subsequent downlink signal to the mobile station. The base stations receiving the uplink signal identify from the data the preferred based station(s) and only the base station(s) identified as the preferred base station(s) transmits a subsequent downlink signal to the mobile station.
