ENHANCING WIRELESS LAN CAPACITY USING TRANSMISSION POWER CONTROL

摘要

A method for mobile communication by access points (22, 23, 25, 27) in a wireless local area network (WLAN) includes transmitting a first downlink signal on a common frequency channel from a first access point to a first mobile station (24), at a first downlink power level, which is adjusted responsively to a first uplink power level transmitted from the first mobile station to the first access point. If the first downlink signal received at a second access point is below a predetermined interference threshold, the second access point may transmit a second downlink signal on the common frequency channel to a second mobile station (29), simultaneously with transmission of the first downlink signal from the first access point to the first mobile station. The capacity of the WLAN may thus be substantially increased.
