Fast secondary cell recovery for ultra-reliable low-latency communication

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may provide, to a first cell, a beam failure indication associated with a beam of a secondary cell. The beam failure indication may be provided via a dedicated physical uplink control channel (PUCCH) resource. The user equipment may provide, based at least in part on providing the beam failure indication, a beam index report to a second cell. The beam index report may be provided to cause recovery of the secondary cell to be triggered. The beam index report may include information that identifies a preferred beam associated with the recovery of the secondary cell. Numerous other aspects are provided.
