Abstract: Aspects relate to measuring and scheduling reference signals. A user equipment (UE) detects reference signals having overlapping resources, and determines a context associated with the reference signals. A Layer 1 (L1) measurement is then performed of at least one reference signal according to a prioritization associated with the context. In another aspect, a network entity determines a scheduling of resources that enables a UE to prioritize performing an L1 measurement of a reference signal from a non-serving cell, and communicates with the UE according to the scheduling. In yet another aspect, a UE communicates with a gNb using transmission configuration indication (TCI) states associated with a corresponding control resource set (CORESET) pool of CORESETs. Beam failure detection (BFD) reference signals are then identified explicitly via a configuration signaling, or implicitly based on the TCI states. The BFD reference signals are then monitored to facilitate detecting a beam failure event.

The base station may transmit, to the UE, the DCI.

Whether a component carrier is included in the list or whether a beam failure detection reference signal set of the one or more beam failure detection reference signal sets is applicable to the component carrier, or both, may be based on whether the component carrier is of a first type configured for a single beam failure detection reference signal set or is of a second type configured for multiple beam failure detection reference signal sets. The UE may monitor one or more component carriers included in the list for beam failure using the one or more indicated beam failure detection reference signal sets.
