Resource allocation method and apparatus

摘要

Embodiments of the present invention relate to the communication field, and disclose a resource allocation method, apparatus, and system, which solve a problem that the size of resource allocation indication information increases with the increase of the transmission bandwidth, and redundancy of physical layer signaling increases with the increase of the transmission bandwidth. The method includes: allocating time-frequency resources in specific bandwidth to a terminal, where the specific bandwidth is a band less than or equal to system bandwidth; determining the size of resource allocation information according to the specific bandwidth; and sending the resource allocation information to the terminal to indicate the allocated time-frequency resources. The embodiments of the present invention are mainly applied to the process in which the base station allocates time-frequency resources to the terminal.

1. In a cellular system, a method for allocating resources to terminals to communicate with a base station, the method executed by the base station, comprising:
allocating multiple discontinuous bandwidths from a system bandwidth of the base station to a terminal; mapping the multiple discontinuous bandwidths to a continuous virtual bandwidth; obtaining allocating information including size information ofthe continuous virtual bandwidth, size information of each discontinuous bandwidth, and position information of each discontinuous bandwidth in the system bandwidth;
sending the allocating information to the terminal; allocating time-frequency resources in the continuous virtual bandwidth to the terminal; determining time-frequency resources allocation information indicating the allocated time-frequency resources according to allocated time-frequency resources and the size information of the continuous virtual bandwidth; sending the time-frequency resources allocation information to the terminal; and wherein:
the allocating information of the multiple discontinuous bandwidths further comprises effective time of the multiple discontinuous bandwidths, and the allocating the time-frequency resources in the continuous virtual bandwidth to the terminal comprises allocating the time-frequency resources in the continuous virtual bandwidth to the terminal within the effective time.
