US Patent 11683216 Beam failure recovery in unlicensed cells

A wireless device receives configuration parameters indicating a first value of a beam failure instance counter and a radio resource of a downlink signal. The wireless device determines the downlink signal is transmitted via the radio resource. The wireless device determines a beam failure instance based on: the determining the downlink signal is transmitted; and a received power of the downlink signal being less than a threshold value. The wireless device increments the beam failure instance counter based on the determining the beam failure instance.
