摘要：Embodiments for bandwidth allocation methods, detecting interference withother systems, and/or redeploying in alternate bandwidth are described. Higher
bandwidth channels may be deployed at channel boundaries (410), which are a subset ofthose for lower bandwidth channels (310), and may be restricted from overlapping.Interference may be detected (930) on primary, secondary, or a combination of channels,and may be detected in response to energy measurements (910) of the various channels.When interference is detected, a higher bandwidth Basic Service Set (BSS)(100) may berelocated to an alternate channel, or may have its bandwidth reduced to avoid
interference. Interference may be detected based on energy measured on the primary orsecondary channel, and/or a difference between the two. An FFT (1010) may be used inenergy measurement in either or both of the primary and secondary channels. Stationsmay also monitor messages from alternate systems to make channel allocation decisions.Various other aspects are also presented.
