Abstract: This disclosure provides systems, methods and apparatus for channel state information reference signal (CSI-RS) resource activation or deactivation within a resource set. In one aspect, a base station (BS) may transmit control signaling to a user equipment (UE) including an indication to switch an activity status of one or more CSI measurement resources within a CSI resource set from an activated state or a deactivated state to the other. The control signaling may include a bitmap indication for the activity status for the one or more CSI measurement resources or a CSI measurement resource identifier for each CSI measurement resource in an activated state. The UE may transmit a CSI report including information from measuring a channel state, a channel interference, or both for the one or more CSI measurement resources based on the activity status of each.

Abstract: Certain aspects are directed to a user equipment (UE) configured to receive reference signals from a network node via multiple resource element groups (REGs) including at least one REG carrying a downlink transmission. In some examples, the UE may be configured to receive, from the network node, communication parameters for a downlink transmission, the communication parameters indicative of a first resource element group (REG) bundle and a second REG bundle. In some examples, the UE may receive the downlink transmission via the first REG bundle. In some examples, the UE may be configured to perform channel estimation of the downlink transmission based on reference signals transmitted via the first REG bundle and the second REG bundle.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a configuration of at least one sounding reference signal (SRS) resource, wherein the configuration indicates a pseudo-random sequence for muting an SRS associated with the at least one SRS resource. The UE may transmit the SRS using the at least one SRS resource based at least in part on the pseudo-random sequence. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a plurality of virtual antenna panels, wherein the plurality of virtual antenna panels correspond to a plurality of groups of antenna ports and map to one or more portions of at least one physical antenna panel. The UE may map a plurality of reference signal resources to the plurality of virtual antenna panels. The UE may transmit, to a base station and based at least in part on the mapping, reference signals using the plurality of reference signal resources. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, an uplink grant for a physical uplink shared channel (PUSCH) that is to overlap in time with a physical uplink control channel (PUCCH) used for hybrid automatic repeat request (HARQ) feedback for at least multicast, the uplink grant including a downlink assignment index (UL-DAI) indication that indicates at least one of: whether the HARQ feedback of the PUCCH is to be multiplexed on the PUSCH, or a size for the HARQ feedback. The apparatus may communicate, with the network entity, in accordance with the UL-DAI indication. Numerous other aspects are described.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication. A user equipment (UE) may receive a downlink control information (DCI) indicating two or more transmission configuration indication (TCI) states for a physical downlink shared channel (PDSCH). The UE may differentiate that the two or more TCI states apply to all demodulation reference signal (DMRS) ports or all transmission layers across all resource blocks and symbols for the PDSCH from TCI states that apply to different sets of DMRS ports or different sets of resource blocks or symbols. The UE may generate a composite quasi-co-location (QCL) based on the two or more TCI states in response to the differentiating. The UE may receive the PDSCH based on the composite QCL.
