Abstract
Devices, methods and computer programs for wireless communications with rotational beam management are disclosed. Information from past beam tracking stages can be used for a next beam tracking stage, since a next beam codebook to be used for beam scanning depends on an earlier beam codebook.

A network node device, comprising:
- a processor;
- and
- a transceiver, in coordination with the processor, configured to:
- transmit a current beam configuration for a beam scanning procedure, the current beam configuration comprising information on a set of beams in a current angular arrangement;
- and
- receive feedback information related to the current beam configuration from a client device,
- wherein the processor is configured to:
- determine a preferred beam of the set of beams in the current angular arrangement based on the received feedback information;
- and
- determine a subsequent beam configuration for the beam scanning procedure, the subsequent beam configuration comprising information on one or more beams in a subsequent angular arrangement, wherein a mean direction of the subsequent angular arrangement corresponds with the direction of the determined preferred beam, and
- wherein the transceiver is further configured to transmit the subsequent beam configuration.
