US 10,772,119 B2 · Scheduling request based beam failure recovery

Abstract

A wireless device transmits a first scheduling request (SR) based on a buffer status reporting procedure. A second SR is triggered in response to initiating a beam failure recovery. The second SR is transmitted via an uplink control channel resource configured for the second SR. A first downlink control information is received via a downlink control channel, as a response to the second SR. Based on receiving the first downlink control information: the first SR is keep pending, and the second SR is cancelled for the beam failure recovery.
