Abstract: A user equipment obtains a first channel state information (CSI)-related quantity and a second CSI-related quantity in at least one of: respective first and second CSI-interference measurement (CSI-IM) resources, or respective first and second CSI-reference signal (CSI-RS) resources in respective first and second slots, and transmits a baseline CSI report based on the first CSI-related quantity in the first slot, and a differential CSI report based on the second CSI-related quantity in the second slot, the baseline CSI report being linked to the differential CSI report. In one example, the first slot is a half-duplex slot, the baseline CSI report is a baseline half-duplex CSI report, the second slot is a full-duplex slot, and the differential CSI report is a differential full-duplex CSI report.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network entity may receive a sounding reference signal (SRS) at a multi-panel system of the network entity, where the multi-panel system includes one or more sounded panels and one or more non-sounded panels. The network entity may estimate a channel to obtain channel state information (CSI) for the one or more sounded panels based at least in part on the SRS. The network entity may estimate CSI for the one or more non-sounded panels based at least in part on the CSI for the one or more sounded panels. The network entity may transmit or receive a communication based at least in part on the CSI for the one or more sounded panels and the CSI for the one or more non-sounded panels. Numerous other aspects are described.

Abstract: Aspects relate to transmission of a sounding reference signal (SRS). A scheduling entity such as a base station may configure the transmission of an SRS by a scheduled entity such as a user equipment (UE). In some aspects, this configuration may be based on the number of antenna ports that the UE will use to transmit the SRS. For example, the scheduling entity may specify that the scheduling entity is to use a first table or a second table to map transmission combs to the maximum number of cyclic shifts. In some aspects, the selection of the first table or the second table may be based on the number of antenna ports that the scheduled entity will use to transmit the SRS.

Abstract: Some aspects described herein relate to receiving, from a network via at least one of multiple transmission/reception points (TRPs), a group common (GC)-downlink control information (DCI) in a first component carrier (CC) that includes a set of blocks intended for one or more UEs, and receiving, based at least in part on the GC-DCI and a subset of the set of blocks that are intended for the UE, one or more downlink reference signals of multiple downlink reference signals over resources in a second CC, where the one or more downlink reference signals are associated with each block of the subset of the set of blocks. Other aspects relate to transmitting the GC-DCI and the one or more downlink reference signals.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE). The method generally includes receiving a downlink control information (DCI) with at least one block configured to trigger aperiodic sounding reference signal (SRS) transmission from the UE on at least one SRS resource set, determining a transmit power control (TPC) command to apply to the A-SRS if the DCI lacks a transmit power control (TPC) command for the at least one SRS set, and transmitting the A-SRS in accordance with the DCI and the determined TPC command.
