Abstract

The present application discloses an interference coordination method and apparatus and relates to the communications field, which are used to solve a problem in the prior art that a terminal device accessing to a micro cell may cause uplink interference to a macro cell base station and lead to a reduction in an uplink capacity of a macro cell. The method provided in the present application includes: determining an uplink capacity target of a macro cell and assigning an uplink interference level to a micro cell according to the uplink capacity target; sending a control message to a micro cell gateway, a micro cell base station controller, or a micro cell base station, where the control message is used to control uplink interference of the micro cell. The present application is applicable to the communications field and is used to control co-channel interference generated by a micro cell.

Description

technical field [0001] The present application relates to the communication field, and in particular to an interference coordination method and device. Background technique [0002] With the development of mobile communication technology, users have higher and higher demands on service quality. In communication systems, system capacity is a key factor affecting service quality. In order to improve the system capacity, small cells (Small Cells) can be introduced into the existing macro cells, so that the number of system cells can be doubled; when the throughput rate of each cell remains unchanged, it can be doubled (or even tenfold). times) to increase the system capacity. A Hetnet network (Heterogeneous Network, heterogeneous network) is formed after a micro cell is introduced into a macro cell. In a Hetnet network, multiple micro cell base stations are deployed around the macro cell base station, so there will be multiple micro cells within the coverage of the macro cel...
