Document Type and Number:
WIPO Patent Application WO/2019/128183
Kind Code:
A1
Abstract:
The present invention provides a multi-user scheduling and resource allocation processing method in a large-scale antenna system, comprising: calculating a corresponding metric matrix according to the metric definition of a system; selecting a pairing group for each resource block according to the metric matrix and the principle of maximizing the metric between a single resource block and a single pairing group; determining the combination of a local optimal pairing group and the resource block; selecting a resource block for a pairing group; screening feasible pairing groups; detecting whether all resource blocks are allocated; if the allocation is completed, proceeding to a next step; if the allocation is not completed, proceeding to construction of a new metric matrix; constructing the new metric matrix; repeating the steps until all resource blocks are allocated; and outputting the mapping relationship between resource blocks and user pairing groups. According to the present invention, the technology of joint processing of user pairing and resource allocation is proposed. Moreover, joint processing is carried out within the selectable space and allocable resource space of the entire user group, and a better performance than the prior art can be realized with limited implementation complexity.
