Abstract
A user device, UE, for a wireless communication network is described. The UE is a sidelink, SL, UE, and is to communicate with one or more further SL-UEs over a sidelink, SL, using more than one antenna or antenna element. The UE is served by a base station of the wireless communication network. The UE is to be assisted by the base station for one or more beam management procedures.

A user device, UE, for a wireless communication network,
- wherein the UE is a sidelink, SL, UE, and is to communicate with one or more further SL-UEs over a sidelink, SL, using more than one antenna or antenna element,
- wherein the UE is served by a base station of the wireless communication network, and
- wherein the UE is to be assisted by the base station for one or more beam management procedures.
A base station for a wireless communication network,
- wherein the base station is to serve a plurality of sidelink UEs, SL-UEs, communicating with each other over a sidelink, SL, using beamforming, and
- wherein the base station is to assist one or more of the SL-UEs in beam management procedures.
A user device, UE, for a wireless communication network,
- wherein the UE is a sidelink, SL, UE, and is to communicate with one or more further SL-UEs over a sidelink, SL, using more than one antenna or antenna elements,
- wherein the UE is to perform beam sweeping using a beam sweeping signal.
A user device, UE, for a wireless communication network,
- wherein the UE is a sidelink, SL, UE, and is to communicate with one or more further SL-UEs over a sidelink, SL, using more than one antenna or antenna elements,
- wherein the UE is to receive from at least one of the further SL-UEs a beam sweeping signal.
A user device, UE, for a wireless communication network,
- wherein the UE is a sidelink, SL, UE, and is to communicate with one or more further SL-UEs over a sidelink, SL, using more than one antenna or antenna elements,
- wherein the UE is to communicate with at least one of the further SL-UEs over the sidelink, SL, using matching beams of the UE and the further SL-UE, and
- wherein, responsive to a certain event, the UE is to perform a beam adjustment, e.g., such that a matching of the beam of the UE and the further SL-UE is maintained.
A method for operating a user device, UE, for a wireless communication network, the method comprising:
- communicating, by the UE which is a sidelink, SL, UE, SL-UE, being served by a base station of the wireless communication network, with one or more further SL-UEs over a sidelink, SL, using more than one antenna or antenna element, and
- assisting the UE, by the base station, with one or more beam management procedures.
A method for operating a base station for a wireless communication network, the method comprising:
- serving, by the base station, a plurality of sidelink UEs, SL-UEs, communicating with each other over a sidelink, SL, using beamforming, and
- assisting, by the base station, one or more of the SL-UEs in beam management procedures.
A method for operating a user device, UE, for a wireless communication network, the method comprising:
