Abstract

Provided are an interference control method and apparatus, a response message sending method and apparatus, a response message forwarding method and apparatus, a communication device, and a communication system. A reference signal sent by a victim base station carries an addressing identifier. The addressing identifier corresponds to route information of a victim node set. Thus, when an aggressor base station monitors the reference signal, an aggressor node set may send a response message to the victim node set according to the addressing identifier, so that the victim base station in the victim node set can respond to the message to determine that the aggressor base station has received the reference signal sent by the victim base station.

Claims20

Dependent claims

An interference control method, comprising:

sending a reference signal carrying an addressing identifier, wherein the addressing identifier corresponds to route information of a victim node set, and the victim node set comprises a victim base station;
determining, according to a response message sent by an aggressor node set, that an aggressor base station receives the reference signal, wherein the aggressor base station belongs to the aggressor node set;
and
performing atmospheric waveguide interference control in cooperation with the aggressor base station;
wherein before sending the reference signal carrying the addressing identifier, the method comprises:
sending monitoring trigger information, the monitoring trigger information being used to trigger a base station which receives the monitoring trigger information and starts reference signal monitoring;
wherein a number of hops is set in the monitoring trigger information, and the number of hops automatically decreases each time the monitoring trigger information passes through a base station or a core network element.

4 more elements

A response message sending method, comprising:

monitoring a reference signal, wherein the reference signal carries an addressing identifier corresponding to route information of a victim node set, and the victim node set comprises a victim base station;
and
sending, after monitoring the reference signal sent by the victim base station, a response message to the victim node set according to the addressing identifier carried in the reference signal, wherein the response message is used for indicating that an aggressor base station monitors the reference signal sent by the victim base station;
wherein the addressing identifier comprises a set identifier of the victim node set, and a mode for sending the response message to the victim node set according to the addressing identifier carried in the reference signal comprises:
mode 1:
querying a network management or a server about route information of a victim base station corresponding to the set identifier, and acquiring, from the network management or the server, the route information of the victim base station corresponding to the set identifier, wherein the route information comprises a base station identifier of the victim base station, a tracking area identity (TAI) of the victim base station, and public land mobile network (PLMN) information of the victim base station;
and
sending the response message to the victim base station according to the route information of the victim base station.

5 more elements

A response message sending method, comprising:

acquiring a monitoring result of a reference signal by a base station belonging to a set center node of an aggressor node set, wherein the reference signal carries an addressing identifier corresponding to route information of a victim node set, the victim node set comprises a victim base station, and the aggressor node set comprises an aggressor base station;
and
sending a response message to the victim node set according to the addressing identifier carried by the reference signal monitored by the aggressor base station, wherein the response message is used for indicating to the victim base station that the aggressor base station monitors the reference signal;
wherein the addressing identifier comprises a set identifier of the victim node set, and a mode for sending the response message to the victim node set according to the addressing identifier carried by the reference signal monitored by the aggressor base station comprises:
mode 1:
querying a network management device or a server about route information of a victim base station corresponding to the set identifier, and acquiring, from the network management device or the server, the route information of the victim base station corresponding to the set identifier, wherein the route information comprises a base station identifier of the victim base station, a tracking area identity (TAI) of the victim base station, and public land mobile network (PLMN) information of the victim base station;
and
sending the response message to the victim base station according to the route information of the victim base station.
