METHOD AND APPARATUS FOR GENERATING/PARSING RESOURCE ALLOCATION INDICATION MESSAGE

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.
