Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) receiving control messages that schedule a first and second set of repetitions of an uplink transmission to respective transmission/reception points (TRPs). The one or more control messages may be indicative of a first redundancy version (RV) sequence that is to be applied to the first set of repetitions and a second RV sequence that is to be applied to the second set of repetitions. The control messages may also indicate a first set of power control parameters and a second set of power control parameters. The UE may map the first and second set of power control parameters to the first and second set of repetitions according to a rule. The UE may transmit the first and second sets of repetitions according to the respective RV sequences and power control parameters.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for enabling L1 (physical layer) and L2 (medium access control (MAC) layer) inter-cell mobility. More specifically, rules and operations performed during L1/L2 based cell handover operations. In certain aspects, a user equipment (UE) is configured to receive, from a network entity of a source cell via at least one of L1 or L2 signaling, a handover command for the UE to handover from the source cell to a target cell. The UE may determine at least one transient period during which the UE is served by both the source cell and the target cell, and perform the handover while communicating with the source cell and target cell during the transient period.

Abstract: Aspects of the present disclosure provide techniques for triggering generation and transmission of a channel state information (CSI) report by the user equipment (UE) in response to issuance of at least one downlink grant by the base station. Additionally, in order to address unique challenges that may arise with respect to traffic collisions and desynchronizations based on downlink grant CSI report triggering (e.g., missing downlink control information (DCI)), aspects of the present disclosure may further implement restrictions for transmission of aperiodic CSI (A-CSI) by the UE on physical uplink control channel (PUCCH) triggered by downlink grant. Additionally, aspects of the present disclosure provide techniques for utilizing a duplicate CSI trigger indication (e.g., indicator in downlink DCI) between multiple messages in order to signal to the UE that the transmission of A-CSI may be multiplexed or merged with another uplink message (e.g., acknowledgement).

In some aspects, a user equipment (UE) receive, from a base station (BS), a first downlink control information (DCI) message scheduling an uplink (UL) data transmission, the first DCI message indicating a first value for an UL schedule timing indicator. The UE activates a timer based at least in part on the first value of the UL schedule timing indicator. The UE monitors a downlink control channel based at least in part on the timer. The UE receives, from the BS, a second DCI message indicating UL schedule timing for the UL data transmission based at least in part on the monitoring.
