Abstract
The present disclosure pertains to a method for beam forming in a wireless communication network, comprising determining an Uplink/Downlink (UL/DL) imbalance of a user equipment wirelessly connected or connectable to a first node of the wireless communication network and determining a location of the user equipment. The method also comprises controlling beam forming based on the determined UL/DL imbalance and the determined location utilizing at least an antenna arrangement controlled by and/or associated to the first node. There are also disclosed related methods, devices and arrangements.

A method for beam forming in a wireless communication network, comprising:
- determining an uplink/downlink (UL/DL) imbalance of a user equipment wirelessly connected or connectable to a first node of the wireless communication network;
- determining a location of the user equipment;
- and
- controlling beam forming based on the determined UL/DL imbalance and the determined location utilizing at least an antenna arrangement controlled by and/or associated to the first node.
A node arrangement for a wireless communication network, comprising:
- an antenna arrangement connected or connectable to a node of the node arrangement;
- and
- control circuitry of a control node of the node arrangement, the control circuitry being arranged to control signaling utilizing the antenna arrangement;
- wherein the control circuitry is adapted to control beam forming utilizing the antenna arrangement based on a determination of a location of at least one user equipment wirelessly connected or connectable to the node arrangement and based on a determination of an UL/DL imbalance of the at least one user equipment.
A base station for a wireless communication network, the base station being adapted for determination of a location of at least one user equipment to which the base station is wirelessly connected or connectable, the base station further being adapted for determination of an UL/DL imbalance of the at least one user equipment, wherein the base station is adapted for control of beam forming based on the determination of the location and the determination of the UL/DL imbalance of the at least one user equipment.
A user equipment for a wireless communication network, the user equipment being wirelessly connected or connectable to at least a first base station and a second base station of the wireless communication network,
- the user equipment being adapted to enter a soft handover state with the first base station and the second base station upon reception of a corresponding message from the wireless communication network and/or a control node of the wireless communication network based on determination of the location of the user equipment and determination of the user equipment being having UL/DL imbalance regarding at least the first base station and the second base station.
