RESOURCE ALLOCATION METHOD AND DEVICE FOR AMPLIFY-AND-FORWARD RELAY NETWORK

摘要

A resource allocation method and device for amplify-and-forward relay network are provided by the present invention. The method includes: obtaining the channel information, which includes the information of a channel between a Base Station (BS) and a Relay Station (RS) and the information of the channels between the RS and each User Equipment (UE); calculating the resource usage information for each UE on each sub-channel pair based on the channel information; and obtaining the number of the Resource Elements (RE) allocated for each UE on each sub-channel pair based on the resource usage information, wherein the obtained number of the RE maximizes a predefined first function. The embodiments of the present invention improve the resource usage efficiency.
