Patent ID: 8437361

Claim:
A method comprising: receiving at a first wireless communication device transmissions sent by a second wireless communication device, wherein the transmissions occupy some or all of a plurality of subchannels within a frequency band that are available for use in the transmission; evaluating the transmissions received at the first wireless communication device in each subchannel for an over-the-air wireless link between the first wireless communication device and the second wireless communication device to identify one or more of the plurality of subchannels having a link quality that is unusable in transmissions such that the one or more of the plurality of subchannels should be disabled; determining time durations that each of the one or more of the plurality of subchannels should be disabled; and independently disabling use of the one or more of the plurality of subchannels in transmissions that are sent by the first wireless communication device to the second wireless communication device during the determined time durations.
