Abstract:
A wireless device transmits one or more preambles in response to initiating a beam failure recovery. The wireless device determines a failure of the beam failure recovery based on a number of transmissions of the one or more preambles exceeding a first number. The wireless device determines a radio link failure in response to the failure of the beam failure recovery. The wireless device starts, based on the radio link failure, a radio resource control (RRC) connection re-establishment procedure with a radio link failure report indicating the failure of the beam failure recovery is a cause of the radio link failure.
