Abstract: A base station may identify an association between a set of physical cell identifiers (PCIs) identifying different transmission reception points (TRPs) and a set of transmission configuration indicator (TCI) states for a user equipment (UE). The base station may transmit a TCI state and PCI association indication to the UE. The UE may receive a downlink transmission using a receive beam associated with a TCI state, and may identify a PCI of the set of PCIs to use to decode the received downlink transmission. In cases where the TCI state used to receive the downlink transmission is associated with multiple PCIs, the UE may select a default PCI from the multiple PCIs, and may decode the received transmission accordingly. In some examples, the UE may receive reference signals from one or more of the serving TRPs and may identify a PCI to use to decode the received reference signals.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a wireless device (e.g., abase station, a user equipment (UE)) may transmit a wake-up message including an indicator of whether an on duration of a discontinuous reception cycle is associated with harvesting energy from a signal transmitted during the on duration. The wireless device may transmit the signal during the on duration based on the wake-up message. In some examples, the UE may determine, from the indicator, whether to harvest energy, decode data or both during the on duration. If both harvesting energy and decoding data, the UE may harvest the energy and decode the data concurrently for at least a portion of the on duration. Additionally, or alternatively, the UE may harvest the energy during a first portion of the on duration and may decode data during a second portion of the on duration.
