摘要：
A method and apparatus is described herein for performing loop power control and transmission power control (TPC) in a wireless network. Described herein are methods including using separate power control loops for communication with an entire wireless network and for point-to-point (P2P) transmissions and separate power control loops for omni-directional and directional beamformed transmissions. Also described herein are methods and apparatuses for requesting clear channel assessment (CCA) measurements and adjusting CCA thresholds and transmission power based on the reported measurements. Methods and apparatuses are also described wherein access points (APs) coordinate transmission power to reduce interference with each other and to determine optimal transmission power to each mobile station (STA).
