TLDR
In this article, a method for suppressing cell co-channel interference is proposed, which is based on a resource allocation strategy, where a frequency band resource of a cell is divided into n frequency domain sections, where n is an integer greater than or equal to two.
Abstract
Specifically disclosed is a method for suppressing cell co-channel interference, wherein same belongs to the technical field of communications. The method comprises: providing, on the basis of a physical cell identifier of a cell, a carrier frequency band for a terminal according to a resource allocation strategy, wherein a frequency band resource of the cell in the resource allocation strategy is divided into n frequency domain sections, n is an integer greater than or equal to two, and a resource allocation sequence is specified. Further provided are a base station, a communication system, an electronic device, and a computer-readable medium.
