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.
