There is provided mechanisms for beam management. A method is performed by a radio transceiver device. The method comprises obtaining an angle spread value for signal paths towards a second radio transceiver device. The method comprises performing a beam management procedure for selecting which directional beam to use for communication with the second radio transceiver device by transmitting or receiving reference signals in a candidate set of directional beams. Which directional beams to include in the candidate set of directional beams is dependent on the angle spread value by the angle spread value determining sparsity of the directional beams in the candidate set of directional beams.

Beam management for a radio transceiver device

A first communications device () for detecting disturbing sound () is provided, operative to acquire a first representation of sound audible in a surrounding () of the first communications device, acquire, from second communications devices (-) which are spatially separated from the first communications device, second representations of sounds audible in the surroundings () of the second communications devices, and determine at least one second representation of sound which represents the same sound originating from the same source of sound. The first communications device is further operative to perform one or both of: i) if a sound level of a second representation of sound representing the same sound from the same source as the first representation of sound exceeds a first sound level threshold, and if the first communications device is proximate to the source of the sound, one or more of: trigger a notification to a user of the first communications device, reduce a volume of media played-out by the first communications device, and stop play-out of media by the first communications device, and ii) if a sound level of the first representation of sound exceeds a first sound level threshold, send a disturbance notification to the second communications device which is proximate to the source of the sound.
