Time-division-based channel collision collaboration in a dynamic frequency hopping wireless regional area network (WRAN)

A system for 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 system comprising:

• at least one Consumer Premise Equipment (CPE) located in an overlapping portion of service areas of at least two WRANs for performing spectrum sensing and for feeding idle channel information back to respective Base Stations (BSs) of the at least two WRANs;
• and
• the BSs of the at least two WRANs for broadcasting a pre-occupation announcement message for at least one qualified idle channel for a next operation time period, for 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 the channel collision state, and for determining, by the BS of the WRAN with the highest priority of a plurality of the at least two WRANs, 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 a channel collision state according to a Quality of Service (QoS) requirement of the BS of the WRAN with the highest priority.
