Distributed management method for direct connection communication users in cellular network

Abstract

The invention discloses a distributed management method for direct connection communication users in a cellular network and relates to the field of communication. Distributed resource allocation and power control can be achieved according to auxiliary information broadcasted by a base station and interference cognitive competence of a client, so that a great deal of information feedback and computation complexity required by central station control can be effectively reduced on the basis of achieving high performance. The distributed management method comprises completing access of direct connection communication users and clustering according to geographical locations in initial phase; performing time domain hash based on density of the direct connection communication users in a cluster to control and schedule density of users after clustering; subjecting scheduled direct connection communication users to Initialization and modification of candidate channels through interference cognition under assistance of the base station; performing channel (frequency domain) hash on direct connection communication users in every cluster and enabling that different direct connection communication users can be hashed in different channels as possible; and performing power adjustment on the direct connection communication users under assistance of the base station after the channels are determined.

Description

technical field [0001] The invention relates to the field of communication, in particular to a distributed interference management method for directly connected communication users under a cellular network. Background technique [0002] In order to improve the utilization rate of resources in the cellular network and alleviate the problems of overloading in some areas of the network, the direct communication in the cellular network (also known as: D2D / P2P / M2M, Device-to-Device, Peer-to-Peer , Machine-to-Machine) has become a development hotspot. Users who adopt the direct communication method communicate directly with other terminal devices in the network to transmit or obtain useful information without switching through the base station. This can reduce the load of the base station to a great extent and improve the utilization rate of system resources. However, severe interference introduced by direct communication users in cellular networks becomes a problem. [0003] I...
