摘要： A method for generating/parsing a resource allocation indication message, a transmitter and a receiver are disclosed. In the method of the present invention, each resource unit is mapped to one bit, and information about service types provided by each serving zone is obtained by mapping an added virtual resource unit to one bit or by secondary mapping. Bits to which part of or all of the above resource units are mapped, or bits to which part of or all of the above resource units and the virtual resource unit are mapped, or bits to which part of or all of the above resource units are mapped and bits obtained by the secondary mapping, constitute a resource allocation indication, and the number of serving zones, the start resource unit and end resource unit of each serving zone and the service type of each serving zone can be learned according to the resource allocation indication and a prearrangement between the transmitter and the receiver. In the present invention, the overhead of indication is unrelated to the number of serving zones to be indicated, and obvious advantages can be obtained when the number of serving zones to be indicated changes in a large range and/or the number of serving zones to be indicated is large.

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.
