Patent ID: 7890061

Claim:
A method comprising: determining to assign a client station an extended bandwidth channel in a wireless communication band of a wireless communication system; receiving an indication from the client station that the client station detected interference in the extended bandwidth channel of the wireless communication band; restricting operation of the client station to a non-extended bandwidth channel in response to the indication from the client station that interference exists on the extended bandwidth channel, wherein restricting operation of the client station to the non-extended bandwidth channel includes: waiting for a re-test trigger that indicates the extended bandwidth channel should be re-measured to determine if interference exists on the extended bandwidth channel; determining whether interference exists on the extended bandwidth channel in response to the re-test trigger; and switching from operation on the non-extended bandwidth channel to operation on the extended bandwidth channel if it is determined that interference does not exist on the extended bandwidth channel; and authorizing operation of the client station on the extended bandwidth channel when interference does not exist on the extended bandwidth channel.
