One implementation involves scanning one or more wireless channels to discover a partner wireless station for a new transmission, by detecting peak energy and beacons on each scanned channel. If a beacon is not detected, then selecting the clearest channel among the scanned channels, and transmitting beacons on the clearest channel. Upon detecting a beacon from a partner station, establishing association with the partner station and selecting a wireless data channel for communication with the partner station. Another implementation involves discovering a partner wireless station to establish a data channel for communication with a discovering station that is associated with a coordinator station, and transmitting a bandwidth reservation request to the coordinator to reserve channel time for control message exchange between the discovering station and the partner station.
FIELD OF THE INVENTION The present invention relates to wireless communication, and in particular to channels for wireless communication.
BRIEF SUMMARY OF THE INVENTION The present invention provides a method and a system for device discovery in wireless communication. One embodiment involves scanning one or more wireless channels to discover a partner wireless station for a new transmission, by detecting peak energy and beacons on each scanned channel. If a beacon is not detected, then the clearest channel is selected among the scanned channels, and then beacons are transmitted on the clearest channel by the discovering station. Upon detecting a beacon from a partner station, association is established with the partner station and a wireless data channel is selected for communication with the partner station.
DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method and a system for wireless communication using a control channel to facilitate communication between wireless stations on a data channel.
