Abstract
Techniques are provided herein to adaptively and independently disable use of subchannels in transmission sent from a first wireless communication device to a second wireless communication device. The first wireless communication device receives transmission sent to it by the second wireless communication device. The transmissions occupy some or all of a plurality of subchannels within a frequency band that are available for use in the transmission. The transmissions received at the first wireless communication device are evaluated in each subchannel for an over-the-air wireless link between the first wireless communication device and the second wireless communication device. Based on the evaluation, zero or more of the plurality of subchannels are independently disabled in transmissions that are sent by the first wireless communication device to the second wireless communication device.
