Problems solved by technology

[0003] Taking the ultra-dense deployment of Small Cell networks as an example, each Small Cell requires an independent base station to support it. With the use of ultra-dense deployment of Small Cell networks, the deployment density of base stations in the same space will also increase. Therefore, whether it is communication The terminal or the Small Cell base station will receive more interference signals from adjacent Small Cell base stations / other Small Cell users, and the interference intensity will also increase due to the shortened distance between communication nodes, which results in Small Cell cell Severe same-layer interference among the same-layer interference, and if the deployment density of cells is reduced in order to reduce the same-layer interference, the system capacity of the ultra-dense deployment network cannot be guaranteed

Abstract

The embodiment of the invention provides an interference coordination method and device, which can reduce interference on a same layer between cells on the premise of guaranteeing the system capacity. The specific scheme comprises the following steps: dividing each cell in a control region into at least one cell cluster, wherein signal interference does not exist between cells included by each cell cluster in the at least one cell cluster; adjusting and controlling base station transmitting power of each cell in each cell cluster in the control region by taking each cell cluster in the at least one cell cluster as a unit. The method and the device are suitable for the field of communication.

Description

technical field [0001] The present invention relates to the communication field, in particular to an interference coordination method and device. Background technique [0002] As the demand for mobile communication services increases, the demand for system capacity of radio communication networks also increases. However, because radio spectrum resources are limited, the system capacity of point-to-point transmission in traditional heterogeneous networks is close to the theoretical limit, so it is necessary to improve the utilization of spectrum resources. Therefore, the newly emerging ultra-dense deployment Small Cell (small cell) network will have great development prospects, because the goal of ultra-dense deployment of Small Cell networks is to maximize spectrum utilization. One definition of ultra-dense deployment of Small Cell networks is in a macro A network of more than 10 Small Cells is deployed in a cell, and the system capacity of the network is proportional to th...
