Beam Failure Recovery Request Procedure

Abstract

A wireless device initiates a beam failure recovery procedure in response to detecting a number of beam failure instances based on a first plurality of reference signals. A beam failure recovery timer is started with a timer value in response to the detecting. A physical layer of the wireless device assesses, during the beam failure recovery timer running, a first radio link quality of a second plurality of reference signals against a threshold. The beam failure recovery procedure is completed in response to the beam failure recovery timer expiring and the first radio link quality being below the threshold. Information indicating that the beam failure recovery procedure failed due to the first radio link quality being below the threshold is reported to a radio resource control layer of the wireless device.
