Beam failure recovery in carrier aggregation
Beam failure recovery (BFR) procedures for wireless communications are described. A wireless device may receive a scheduling request configuration for a first cell that indicates uplink resources dedicated to BFR of a second cell and/or uplink resources configured for scheduling requests. A beam failure for a second cell may occur at a time that the wireless device has no uplink resources dedicated to BFR. The wireless device may use (e.g., based on a type of data or resource) an uplink resource configured for scheduling requests to report the BFR.
