PROBLEM TO BE SOLVED: To provide a method and apparatus for conducting peer-to-peer communications while performing channel hopping among two or more wireless channels, at least one of which is a restricted channel.SOLUTION: One type of restricted channel requires the use of DFS for avoiding use of the channel during certain circumstances. Communicating peers may synchronize a channel-hopping sequence with TBTTs of the restricted channel, so that they switch to such a channel in time to capture a beacon and determine whether the channel is free. If the channel is free, or if no beacon is received, they may immediately begin or resume their communications. They may also quiesce just before another TBTT so as to capture that beacon. |
