METHOD AND APPARATUS FOR UPLINK POWER CONTROL FOR WIRELESS LAN STATIONS

摘要

Techniques and apparatus for controlling the transmit power of an uplink (UL) signal from a user terminal in a wireless communications system in an effort to achieve some target characteristic, such as a target carrier- to- interference (C/I) ratio, at an access point (AP) are provided. The method comprises: receiving a plurality of uplink signals, determining power of the received plurality of UL signals; determining adjustment information for a UL signal in the plurality of UL signals based on at least the power of the received UL signals and a target carrier- to- interference (C/l) ratio; and transmitting the adjustment information. The user terminal and the AP may compose part of a multiple - input multiple - output (MIMO) communication system utilizing spatial - division multiple access (SDMA) techniques.
