Abstract
There is provided mechanisms for assisting a UE-side beam selection procedure. A method is performed by a network node. The method comprises estimating TRP-side angular information of a CE from uplink signalling received from the UE at a TRP of the network node. The method comprises reporting the TRP-side angular 5 information towards the UE and configuring the UE to perform a UE-side beam selection procedure based on the TRP-side angular information.

1-8. (canceled)
A method for performing a user equipment (UE)-side beam selection procedure, the method being performed by a UE (300), the method comprising:
- transmitting (S202) uplink signalling towards a transmission and reception point (TRP) (140) of a network node (200);
- receiving (S204), from the network node (200), reporting of TRP-side angular information of the UE (300) from the uplink signalling and configuration for the UE (300) to perform a UE-side beam selection procedure based on the TRP-side angular information;
- and
- selecting (S206), as part of performing the UE-side beam selection procedure, a beam to use for communication with the TRP (140), wherein the beam has a pointing direction that is selected as a function of the TRP-side angular information.
A network node (200) for assisting a user equipment (UE)-side beam selection procedure, the network node (200) comprising processing circuitry (210), the processing circuitry being configured to cause the network node (200) to:
- estimate TRP-side angular information of a UE (300) from uplink signalling received from the UE (300) at a transmission and reception point (TRP) (140) of the network node (200);
- and
- report the TRP-side angular information towards the UE (300) and configure the UE (300) to perform a UE-side beam selection procedure based on the TRP-side angular information.

26-29. (canceled)
A computer program (1220a) for assisting a user equipment (UE)-side beam selection procedure, the computer program comprising computer code which, when run on processing circuitry (210) of a network node (200), causes the network node (200) to:
- estimate (S102) transmission and reception point (TRP)-side angular information of a UE (300) from uplink signalling received from the UE (300) at a TRP (140) of the network node (200);
- and
- report (S104) the TRP-side angular information towards the UE (300) and configuring the UE (300) to perform a UE-side beam selection procedure based on the TRP-side angular information.
