摘要
A method of and 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 is provided. The method includes 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 at least two WRANs, a pre-occupation announcement message for a qualified idle channel, and determining, by a WRAN with the highest priority of the at least two WRANs, a time resource allocation for WRANs in a channel collision state of the at least two WRANs. The method addresses problems, such as a large delay and impaired wireless access due to an absence of an idle channel for adjacent WRANs, may be avoided, while the WRANs may maintain their QoSs. Therefore, transmission power of a WRAN during non-operation period may be conserved.
