Note: This is not a TCI state, rather a valid QCL assumption. 6.12.2.4 Beam Recovery Beam recovery is used for rapid link reconfiguration against sudden blockages. The beam recovery procedure involves several stages. In the first instance, the UE needs to detect that it is in a state in which the beam on which is operating/monitoring is not available anymore; this is called beam failure detection (BFRD). Following this, the UE needs to identify new beams for transmission, and
