Abstract

Systems, apparatuses, and methods are described for wireless communications. A base station may indicate one or more resources for beam failure recovery. The one or more resources may comprise one or more resources for downlink transmission and one or more resources for uplink transmission. A beam failure recovery may be based on the one or more resources for downlink transmission. A wireless device may send, based on the one or more resources for uplink transmission, uplink information for beam failure recovery.
