POWER ADAPTIVE MULTI-SUBBAND CLEAR CHANNEL ASSESSMENT

Abstract:

A configuration to configure an apparatus to perform a clear channel assessment based on one or more transmission power levels. The apparatus measures at least one energy sensing measurement over an operating channel. The apparatus determines whether the operating channel is available for transmission based on a threshold determination for one or more transmission power levels. The apparatus transmitting on the operating channel upon the determination that the operating channel is available for transmission for the one or more transmission power levels, wherein the one or more transmission power levels are less than the threshold determination.
