Multi-RET actuators include a plurality of shafts that have respective axially-drivable members mounted thereon. Each of axially-drivable member is mechanically linked to a respective one of a plurality of phase shifters. The multi-RET actuator further includes a motor having a drive shaft and a gear system that is configured to selectively couple the motor to the respective shafts. The gear system is configured so that rotation of the drive shaft in a first direction creates a mechanical linkage between the motor and a first of the shafts 1340/1342, and rotation of the drive shaft in a second direction that is opposite the first direction rotates the first of the shafts.

Apparatus for controlling antenna of mobile-communication base station

There is provided a method for utilizing antenna beam information. The method is performed by a network node. The method comprises acquiring antenna beam information indicative of a direction of a wireless device (WD) specific beam of the network node. The method comprises classifying the acquired antenna beam information into a cell specific beam category based on an angular difference between the direction and a direction of main lobe of a cell specific beam of the network node. The method comprises performing at least one of a load balancing action of the wireless device and a radiation beam pattern change related to the cell specific beam category.

Utilization of antenna beam information

An actuator assembly for adjusting attributes of an antenna array. The actuator assembly provides a multi-RET actuator including a plurality of linear actuators, each including an actuator spur gear, a carriage assembly with an actuator drive motor mounted on a car and a nut attached to the car. A positioning motor is coupled to a lead screw and the nut is threaded onto the lead screw. The car travels on a guide so that the positioning motor and lead screw may be operated to bring the carriage assembly into engagement with a desired one of the linear actuators.

Methods of configuring base station antennas are provided in which reconfiguration data is transmitted to a controller of the antenna from a remote location. Connections between a plurality of remote electronic tilt (RET) units that are mounted within the antenna and a plurality of control ports of the antenna are then reconfigured in response to receipt of the reconfiguration data.
