Abstract

The embodiment of the invention provides a method and device for cell interference coordination. The method for the cell interference coordination comprises the steps that a first base station generates interference coordination information which comprises relative narrow-band transmitted power threshold value information corresponding to wireless resources of a designated dimension, wherein the designated dimension comprises at least one of time or frequency or space; the first base station sends interference coordination information to a second base station to enable the second base station to determine an interference coordination strategy according to the interference coordination information, and interference, on the same secondary band, of the first base station and the second base station is reduced. The method and device enables the base stations to determine the interference coordination strategy according to the interference coordination information sent by adjacent base stations, the interference, on the same secondary band, of a base station and an adjacent base station is reduced, and therefore the problem of same frequency interference in an LTE network deployment scene is resolved.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and more specifically, to a method and device for interference coordination. Background technique [0002] In a wireless network, if adjacent base stations work on the same center frequency point, co-channel interference will be caused. Generally, the carrier frequency band involves two components, the center carrier frequency and the corresponding bandwidth. For example, in a Long Term Evolution (LTE) network, an evolved base station (evolved Node B, eNB) works at a center frequency of 2 GHz (GHz) when sending downlink signals, and the bandwidth is 5 MHz (MHz) , usually the 5 MHz bandwidth is further divided into resource blocks (Resource Block, RB), also called physical resource blocks (Physical Resource Block, PRB). Each PRB consists of 12 carriers, and each carrier is usually 15KHz or 7.5KHz. A user equipment (User Equipment, UE) located in a cell edge area may receive inter...
