Antenna control system in base station system and configuration method therefor

A multi-ALD (Antenna Line Device) system for controlling a plurality of antennas, the multi-ALD system comprising:

• a plurality of ports configured to be linked to a plurality of base stations, respectively;
• and
• a plurality of ALDs, comprising a master ALD and other ALDs, configured to control the plurality of antennas, wherein the master ALD is configured to directly communicate with other ALDs through communication buses between the master ALD and the other ALDs,
• wherein each of the plurality of ALDs is linked to one of the plurality of ports for communication with each other, and configuration of the multi-ALD system is changed such that an antenna is controlled or a port is linked to one of the plurality of ALDs according to a configuration command received by the master ALD from one of the plurality of base stations from a first configuration to a second configuration, wherein in the first configuration, a first antenna among the plurality antennas is controlled by a first ALD among the plurality of ALDs, and in the second configuration, the first antenna is controlled by a second ALD among the plurality of ALDs, the second ALD being different from the first ALD,
• wherein the configuration command comprises:
• configuration information indicating updated interconnections between the plurality of ALDs and the plurality of antennas.

An ALD (Antenna Line Device) operable in a multi-ALD system for controlling a plurality of antennas, the multi-ALD system being configured to operate in a plurality of configurations, wherein the multi-ALD system comprises:

• a plurality of ALDs, including the ALD, each being configured to control one or more of the plurality of antennas, the plurality of ALDs being configured to directly communicate with each other through communication buses;
• and
• a plurality of base stations each being associated with at least one of the plurality of ALDs according to a configuration of the multi-ALD system,
• wherein another ALD is associated with a first base station and controls a first antenna of the plurality of antennas in a first configuration, and the another ALD is associated with a second base station and controls a second antenna of the plurality of antennas in a second configuration,
• wherein the ALD is configured to:
• receive a first message from one of the plurality of base stations while in the first configuration, the first message instructing the ALD to change the configuration of the multi-ALD system, and
• transmit a second message to the another ALD in response to reception of the first message,
• wherein the second message comprises first set of information which instructs the another ALD to be associated with the second base station or instructs the another ALD to control the second antenna.
