Selection of beam for reception of signals
There is provided mechanisms for adapting which beam to use for reception of signals. A method is performed by a receiving radio transceiver device. The receiving radio transceiver device is capable of receiving the signals using at least one beam selected from a set of beams. Each beam in the set of beams has a backup beam. The method includes receiving signals from a transmitting radio transceiver device while using a first beam selected from the set of beams. Signal receipt at a decreasing quality level while using the first beam is detected. The decreasing quality level is caused by interfering transmission from another transmitting radio transceiver device. In response thereto, a temporary switch to the backup beam of the first beam is initiated, without performing any beam training, for continued reception of signals from the transmitting radio transceiver device.
