Abstract

The embodiment of the invention provides an interference signal coordination method and device. The method comprises the following steps of: acquiring first reference signal receiving power which is transmitted by a user terminal and used for measuring a serving cell by the user terminal and second reference signal receiving power which is acquired by measuring a target adjacent cell by the user terminal, obtaining a difference value; according to the first reference signal receiving power and the second reference signal receiving power, obtaining a difference value; according to the difference value, the second reference signal receiving power and a preset grouping strategy, determining an interference type of the user terminal to the target adjacent cell; and according to the interference type of the user terminal and a preset frequency band distribution strategy, adjusting the frequency band which can be used by the user terminal for the target adjacent cell, thereby achieving the interference grouping and frequency band adjustment of the user terminal, and completing the interference signal coordination.

Description

technical field [0001] Embodiments of the present invention relate to the field of network communication technologies, and in particular to a method and device for coordinating interference signals suitable for sectorized co-frequency networking. Background technique [0002] In the current communication system, according to different networking forms, it can be divided into same-frequency networking (the multiplexing factor between cells is 1), different-frequency networking (the multiplexing factor between cells is 3 or more); Under the network, different adjacent cells use different frequency bands, and there will be no inter-cell interference, or only a small inter-cell interference (interference signals from non-adjacent and farther cells), but the disadvantage is that each cell The available bandwidth becomes 1 / 3 or 1 / N of the available bandwidth of the entire system. Overall, although the interference suppression method is relatively simple, the overall throughput is ...
