Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media for a user equipment (UE) to perform layer 1 (L1) measurements of a candidate cell for an L1/L2 mobility procedure. The UE receives, from a current serving cell, a configuration of a channel state information (CSI) reference signal (RS) measurement resource for L1 measurements of a candidate cell. The UE measures a signal transmitted from the candidate cell based on whether the candidate cell is an intra-frequency candidate cell or an inter-frequency candidate cell. The UE may transmit a CSI report including the L1 measurements of the candidate cells to the current serving cell.

Abstract: Certain aspects of the present disclosure provide techniques for a user equipment (UE) to receive, via a first active cell serving the UE, a first control message activating a set of transmission configuration indicator states associated with a set of candidate cells that are inactive at the UE. The UE may receive, via the first active cell after receiving the first control message, a second control message indicating for the UE to switch to a second cell of the set of candidate cells. In response to receiving the second control message indicating for the UE to switch to the second cell, the UE may switch to communicating with the second cell using a first transmission configuration indicator state of the activated set of transmission configuration indicator states.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink control information (DCI) transmission that indicates a unified transmission configuration indicator (TCI), wherein the DCI transmission comprises a semi-persistent scheduling (SPS)-release DCI transmission releasing an SPS physical downlink shared channel (PDSCH) configuration. The UE may transmit hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback using a HARQ-ACK codebook, wherein the HARQ-ACK feedback comprises an acknowledgment (ACK) to indicate successful reception of the unified TCI in the DCI transmission or a negative acknowledgement (NACK) to indicate a failed reception of the unified TCI in the DCI transmission. Numerous other aspects are described.
