Patent ID: 7924869

Claim:
A method of time-division-based channel collision collaboration in a wireless communication system including at least two Wireless Regional Area Networks (WRANs) with overlapping service areas that employ dynamic frequency hopping, the method comprising: performing, by at least one Consumer Premise Equipment (CPE) located in an overlapping portion of service areas of at least two WRANs, spectrum sensing and feeding idle channel information back to respective Base Stations (BSs) of the at least two WRANs; broadcasting, by each of the BSs of the at least two WRANs, a pre-occupation announcement message for a qualified idle channel for a next operation time period; receiving, by a BS of a WRAN with a highest priority of a plurality of the at least two WRANs in a channel collision state, bandwidth request information from at least one other of the plurality of WRANs in a channel collision state; and determining, by the BS of the WRAN with the highest priority, a time resource allocation in the next operation time period on the qualified idle channel for the WRAN with the highest priority and at least one other of the plurality of WRANs in the channel collision state according to a Quality of Service (QoS) requirement of the BS of the WRAN with the highest priority.
