A cell user processing method, device and centralized icic equipment

Abstract

The invention provides a cell user processing method and device, and centralized ICIC (Inter-Cell Interference Coordination) equipment. The method comprises the following steps of receiving a first edge user number of each cell at a first point under a plurality of base stations reported by a plurality of base stations in a plurality of original CoMP (Coordinated Multiple Points Transmission / Reception) cooperative groups; judging whether the first edge user number exceeds a preset first threshold value to obtain a first judging result; and when the first judging result indicates that the first edge user number of a first cell at the first point exceeds the first threshold value, re-dividing the original CoMP cooperative groups to a plurality of first dynamic CoMP cooperative groups in order to affirm edge users of the first cell at the first time point as central users in the first dynamic CoMP cooperative groups. Through detecting the gathering degree of the users at the cell edge, the edge users of the first cell at the first time point are re-divided to the central users in the first dynamic CoMP cooperative groups, so that a CoMP technology can be guaranteed to coordinate interference quickly, and the spectrum effectiveness of the cell edge is improved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a cell user processing method, device and centralized ICIC equipment. Background technique [0002] Long Term Evolution (LTE) downlink adopts Orthogonal Frequency Division Multiplexing (OFDM) technology, so that the problem of intra-cell interference is basically solved. But its inter-cell interference (Inter-Cell Interference, ICI) is more serious than the code division multiple access (Code Division Multiple Access, CDMA) system. [0003] In order to coordinate inter-cell co-channel interference, an inter-cell interference coordination (Inter-Cell Interference Coordination, ICIC) technology is used in LTE networking. The basic idea of ​​ICIC technology is to control inter-cell interference by managing radio resources. It is a multi-cell radio resource management technology that considers resource usage and load in multiple cells. [0004] ICIC technology is a slow radio ...

AI Technical Summary

Problems solved by technology

[0013] However, in the actual network, users are often in a mobile state, and it is easy to form a clustering scene of edge users, resulting in an unbalanced load at the edge of the network cell, that is, at the edge of some overlapping cells, users gather, resulting in a large network load in this area ; In some overlapping cells, users leave, and the network load in this area is light

The existing static grouping scheme cannot adapt to the scenario where the load of the cell edge network is unbalanced due to user movement, and cannot well realize the optimal allocation of wireless resources
