US 2019/0319731 A1 · INTERFERENCE CANCELLATION METHOD AND BASE STATION

Abstract

Embodiments of this application disclose an interference cancellation method and a base station. The method in the embodiments of this application may include obtaining, by a first base station, system information of a neighboring cell. The method may also include determining, by the first base station, interference channel information of a second base station to the first base station based on the system information, where the second base station is a base station in a coverage area of the neighboring cell. Furthermore, the method may also include receiving, by the first base station based on the interference channel information, an uplink signal sent by user equipment in a coverage area of the first base station.

An interference cancellation method, comprising:

receiving, by a second base station, interference channel information of the second base station to a first base station that is sent by the first base station, wherein the interference channel information is determined by the first base station based on system information, and the system information is system information of a cell in which the second base station is located;
and
sending, by the second base station, a downlink signal to user equipment in a coverage area of the second base station based on the interference channel information.

A first base station, comprising:

a processor;
and
a non-transitory computer-readable storage medium coupled to the processor and storing programming instructions for execution by the processor, the programming instructions instruct the processor to:
obtain system information of a neighboring cell;
determine interference channel information of a second base station to the first base station based on the system information, wherein the second base station is a base station in a coverage area of the neighboring cell;
and
receive, based on the interference channel information, an uplink signal sent by user equipment in a coverage area of the first base station.
