Method, apparatus, device, and system for reducing control channel interference

Disclosed are a method, an apparatus, a device, and a system for reducing control channel interference. The method comprises: acquiring configuration information of a control channel, wherein the configuration information comprises at least one of the following information: a configuration period of the control channel, resource occupation indication information, and a start position of the configuration period, the resource occupation indication information is used for indicating a physical resource block (PRB) occupied by the control channel in the configuration period, and the start position of the configuration period is used for indicating a corresponding start point when the configuration period starts; and sending the configuration information to a neighboring base station, so that the neighboring base station adjusts according to the configuration information to reduce interference to the control channel of the base station. According to the embodiments of the present invention, after receiving the configuration information, the neighboring base station can precisely acquire the PRB occupation condition of the control channel in a serving base station, and corresponding adjustment can be made to reduce the interference to the serving base station, which avoids conflicts and effectively solves the problem of mutual control channel interference between base stations.
