Embodiments of the present invention provide a remote electrical tilt unit, a base station, and a method for managing a remote electrical tilt antenna. The method includes: receiving, by the remote electrical tilt unit, permission configuration information sent by a first base station through a group of AISG ports of the remote control unit; configuring management permission of the first base station on the remote electrical tilt unit according to the permission configuration information, where the management permission includes at least control permission and query permission, and control permission on the remote electrical tilt unit can be allocated to only one base station. In this way, multiple base stations jointly manage a remote electrical tilt unit in a remote electrical tilt antenna, and a problem that it is difficult to locate and troubleshoot a fault when configuration of the remote electrical tilt unit is incorrect is resolved.

Remote electrical tilt unit, base station, and method for managing remote electrical tilt antenna

Remote electrical tile unit, base station, and method for managing remote electrical tilt antenna

An interface extension apparatus is presented, which includes N input interfaces and M output interface, where the input interfaces are connected to at least one base station, and the output interfaces are connected to an RET. The apparatus obtains device information of each RET control device in multiple RET control devices; creates an agent for each RET control device according to the device information, where a mapping relationship exists between each RET control device and the corresponding agent; then modulates, using the agent corresponding to the RET control device, a control signal that is received from the at least one base station; and further sends a modulated control signal to a corresponding RET. The embodiments of the present disclosure are used by the multiple base stations to simultaneously manage the multiband RET antenna.

Signal transmission method, interface extension apparatus, and communications system

Embodiments of the present application relate to a matching method. The method includes: selecting, by a base station, a remote electrical tilt unit and sending instruction information to a signal transmitter, where the instruction information is used to instruct the signal transmitter to connect to an antenna radio frequency port corresponding to the remote electrical tilt unit and enable the signal generator to generate a signal. The method also includes receiving, by the base station, the signal when the signal reaches the antenna radio frequency port through a signal coupling unit and is sent by using the antenna radio frequency port. The method also includes selecting, by the base station, a target sector according to a background noise value of each base-station radio frequency port.
