Embodiment Construction

[0054] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.

[0055] The inter-cell interference coordination method for mobile communication systems proposed by the present invention includes the design of the following aspects:

[0056] 1. The base station sends ICIC measurement configuration information to the user equipment, including the conditions for judging the ICIC attribute of the user equipment (cell center user or cell edge user), the timing of sending the ICIC measurement report, etc.

[0057] 2. Based on the measurement results of the serving cell and co-frequency adjacent cells, combined with the ICIC measurement configuration information configured by the base station, the user equipment independently determines the ICIC user attribute of the user equipment, that is, the user at the center of the cell or the user at the edge of the cell, and sends it to the base statio...

Abstract

The invention discloses an inter-cell interference coordination method and system for a mobile communication system, and the method comprises the steps that a base station sends ICIC measure configuration information based on an RRC layer; user equipment determines autonomously whether its ICIC attribute is a cell center user or a cell edge user based on a measure result of a service cell and a co-frequency neighboring cell in combination with the ICIC measure configuration information sent from the base station to the user equipment; the user equipment sends an ICIC measure report to the base station through a corresponding MAC control unit; the base station obtains the current ICIC attribute of the user equipment based on the ICIC measure report sent by the user equipment, and takes the current ICIC attribute as the reference basis for wireless resource scheduling to realize inter-cell interference coordination. According to the invention, the signaling cost of the measure report for inter-cell interference coordination can be effectively reduced; and wireless resources can be saved.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and system for coordinating inter-cell interference in a mobile communication system. Background technique [0002] Inter-cell interference is a major interference problem faced by a mobile communication system using co-frequency networking, such as LTE (Long Term Evolution). Inter-cell co-channel interference will affect the communication quality of uplink and downlink, especially cell edge users are more likely to be significantly interfered, resulting in the decline of throughput performance and user experience. [0003] Inter-cell Interference Coordination (hereinafter referred to as ICIC) is an interference reduction technology for mobile communication systems in the same frequency network. Its principle is that the base station equipment on the network side classifies user equipment in the Edge users who suffer from inter-cell interference adopt a reaso...
