Abstract: A method is provided by the present invention, comprises determining communication channel quality from a first wireless communications device to one or more other wireless communications devices, and assigning a zone/subband and corresponding power level to the one or more other wireless communications devices based on the communication channel quality. The method is directed toward at least addressing the interference from neighboring Access Points (APs), and reducing interference between devices using different power zones/subbands when the wide-band of Orthogonal Frequency-Division Multiple Access (OFDMA) based technologies were adopted in Wi-Fi systems for unlicensed bands.

Abstract: Some wireless communications environments, such as Wi-Fi, may include inexpensive power amplifiers where the power adjustment may not be accurate, and may also include pathloss measurement errors that are high enough to degrade performance of a power control algorithm. To address this issue, an exemplary aspect is directed toward a finite state power control algorithm and technique that, while designed for next generation Wi-Fi standards, such as 802.11ax, can in general be used with any wireless communication protocol or standard.
