Selection of default path loss reference signal or default spatial relation

Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, as a default path loss reference signal (PLRS), a reference signal (RS) resource that corresponds to an active physical downlink shared channel (PDSCH) transmission configuration indicator (TCI) state of an active downlink (DL) bandwidth part (BWP) if a control resource set (CORESET) is not provided in the active DL BWP. The UE may receive the default PLRS. In some aspects, the UE may select, as a default spatial relation for a physical uplink control channel (PUCCH) communication, a spatial relation that corresponds to an active PDSCH TCI state of an active DL BWP if a CORESET is not provided in the active DL BWP. The UE may receive the PUCCH communication using a TCI state that corresponds to the default spatial relation. Numerous other aspects are described.
