Title: BEAM SELECTION FOR A RADIO TRANSCEIVER DEVICE
Abstract:
There is provided mechanisms for beam selection. A method is performed by a first radio transceiver device. The method comprises obtaining link quality estimates of a radio signal conveyed to the first radio transceiver device from a second radio transceiver device by means of at least a first beam taken from a first beam set and a second beam. The second beam is wider than the first beam. The method comprises selecting which one of the first beam and the second beam to use for continued communications of radio signals with the second radio transceiver device in accordance with a comparison between the link quality estimates of the first beam and compensated link quality estimates of the second beam.
