Abstract

The embodiment of the invention provides an interference coordination method and device. The cell interference coordination method comprises the steps that a first base station sends negotiation request information to a second base station, wherein the negotiation request information comprises negotiation contents, the negotiation contents comprise identification information of user equipment UE, or scheduling information, or a storage time of historical scheduling information, or a length of a time domain or a frequency domain of the historical scheduling information, and the scheduling information or the historical scheduling information comprises a sounding reference signal SRS sent by the UE, or configuration information used by the UE for sending the SRS, or scheduled wireless resource information of the UE. By adopting the interference coordination method and device provided by the embodiment of the invention, the base station can determine an interference coordination strategy according to the interference coordination information sent by the adjacent base station to reduce the interference of the base station and the adjacent base station on the same sub-band, in order to solve the same frequency interference problem in an LTE network deployment scene.

Description

[0001] This application is a divisional application of an invention patent application with the application number 201210052066.6, the application date is March 1, 2012, and the invention title is "Method and Device for Interference Coordination". technical field [0002] Embodiments of the present invention relate to the communication field, and more specifically, to a method and device for interference coordination. Background technique [0003] 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 a downlink signal, with a bandwidth of 5 MHz. Usually, the 5 MHz bandwidth is further divided into resource blocks (Resource B...
