The present application provides an interference coordination method and apparatus, pertaining to the technical field of communications, and capable of resolving the problem in which, when the sizes of scheduling resource elements of two eNBs are different, one of the eNBs cannot accurately determine interference between the two eNBs according to interference coordination information of the other eNB, and therefore cannot determine scheduling information of the eNB. The interference coordination method comprises: a first access network device acquiring coordination information and reference information, the coordination information being used to coordinate interference between the first access network device and a second access network device, the reference information being used to indicate the size of an interference coordination resource element, and the coordination information being determined according to the size of the interference coordination resource element; the first access network device determining scheduling information of the first access network device according to the coordination information and the reference information; and the first access network device communicating with a terminal device according to the scheduling information.
Description
technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to an interference coordination method and device. Background technique [0002] During the networking process, there is a scenario where the coverage areas of two different cells overlap. In this scenario, the edge frequency resources configured for two cells (for example, cell A and cell B) are the same. When the edge terminal device in cell A and the edge terminal device in cell B use the same edge frequency resource at the same time, the access and services of the edge terminal device in cell A will be affected, and the access and service of the edge terminal device in cell B will be affected. It will also be affected, that is, interference occurs between cell A and cell B, which affects the experience of edge users in cell A and edge users in cell B. [0003] In the prior art, inter-cell interference coordination (Inter Cell Interference Co...
