Abstract
There are 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.

(canceled)
A user equipment (UE) for beam selection, the UE comprising:
- a processing circuitry, wherein the processing circuitry includes one or more processors for controlling operation of the UE;
- one or more transmitters for communication with a radio transceiver device;
- and
- one or more receivers for communication with the radio transceiver device, wherein the UE is configured to:
- receive, from the radio transceiver device, a first radio signal using a first beam;
- obtain a first link quality estimate of the first radio signal;
- receive, from the radio transceiver device, a second radio signal using a second beam, wherein the second beam is wider than the first beam;
- obtain a second link quality estimate of the second radio signal;
- obtain a selection of one of the first and second beams to use for communicating with the radio transceiver device;
- and
- use the selected beam to communicate with the radio transceiver device.
A network node for configuring a user equipment (UE) for beam selection, the network node comprising:
- a processing circuitry, wherein the processing circuitry includes one or more processors for controlling operation of the network node;
- one or more transmitters for communication with the UE;
- and
- one or more receivers for communication with the UE, wherein
- the network node is configured to:
- configure the UE to obtain a selection of one of first and second beams to use for communicating with a radio transceiver device, wherein the selection of one of the first and second beams is based on a first link quality estimate of a first radio signal received from the radio transceiver device using the first beam and a second link quality estimate of a second radio signal received from the radio transceiver device using the second beam;
- and
- configure the UE to communicate with the radio transceiver device using the selected beam, and
- the second beam is wider than the first beam.
A method performed by a user equipment (UE) for beam selection, the method comprising:
- receiving, from a radio transceiver device, a first radio signal using a first beam;
- obtaining a first link quality estimate of the first radio signal;
- receiving, from the radio transceiver device, a second radio signal using a second beam, wherein the second beam is wider than the first beam;
- obtaining a second link quality estimate of the second radio signal;
- obtaining a selection of one of the first and second beams to use for communicating with the radio transceiver device;
- and
- using the selected beam to communicate with the radio transceiver device.
