Title:
SEMI-DYNAMIC OVERLAPPING CLUSTERING ALGORITHM FOR DENSE DISTRIBUTED WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/233452
Kind Code:
A1
Abstract:
Disclosed in the present invention is a semi-dynamic overlapping clustering algorithm for a dense distributed wireless communication system. The method comprises: first, under a condition of limiting the scale of a cluster, a central processing unit performing semi-dynamic non-overlapping clustering on remote access units (RAUs) by using long-term information state information acquired periodically; then, determining cluster edge users by setting a threshold value; then, respectively calculating an average large-scale fading of each cooperative cluster to edge users of the current cluster and other clusters, and determining overlapping users by means of ratio values; finally, each cooperative cluster performing joint transmission on the users in the cluster whilst avoiding interference to the overlapping users, so as to form a virtual overlapping cluster. The present invention is user-centric, uses long-term channel information to perform overlapping clustering, is adapted to a movement change of a user position, improving the quality of service of a cluster edge user, and improving the system throughput, and has the advantages of low algorithm complexity and low signaling overheads.
