Abstract:
Beam failure recovery (BFR) procedures for wireless communications are described. When beam failures occur on secondary cells, wireless devices may trigger a BFR proceudre via an uplink resource for BFR. If a beam failure occurs for a secondary cell at a time that a wireless device does not have an uplink resource for BFR, the wireless device may perform one or more other actions for BFR of the secondary cell.
