TIMING ADVANCE DETERMINATION FOR PHYSICAL UPLINK CONTROL CHANNEL MESSAGE WITH LINK RECOVERY REQUEST

Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node associated with a first serving cell, a first beam failure detection reference signal (BFD-RS) set and a second BFD-RS set. The UE may transmit, to a network node associated with a second serving cell associated with multiple timing advance groups (TAGs), based on triggering of beam failure recovery for the first BFD-RS set, a physical uplink control channel (PUCCH) message that carries a link recovery request (LRR) associated with the first BFD-RS set, the PUCCH message being associated with a TAG that is based on one or more of: the second BFD-RS set, a predefined rule, or a TAG or control resource set (CORESET) pool index value associated with the PUCCH message. Numerous other aspects are provided.
