Abstract: Certain aspects of the present disclosure provide techniques that may be executed by a new radio (NR) gNB for sending signaling to a user equipment (UE), which may indicate information that may enable the UE to measure synchronization signal blocks (SSBs) that each have an associated range and an associated direction, for performing an initial access procedure.

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: 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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine a time domain interleaving configuration to be used for a transport block of a communication, wherein the time domain interleaving configuration maintains a frequency domain resource distribution of a frequency domain resource mapping scheme used for the transport block, and transmit the communication on one or more physical shared channels using the time domain interleaving configuration for the transport block of the communication. 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 a first sensing signal transmitted by a base station. The UE may determine a preferred sensing direction for a second sensing signal based at least in part on the first sensing signal. The UE may transmit a directional sensing signal request to the base station. The directional sensing signal request may include information indicating the preferred sensing direction for the second sensing signal. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first configuration of one or more channel state information reference signal resources and a second configuration of a channel state information report associated with the one or more channel state information reference signal resources. In some cases, the second configuration may include at least one of an indication of a codebook, a set of codebook restriction sets, and a configured bandwidth. The UE may then identify a mapping between one or more frequency-domain subbands of the configured bandwidth and each codebook restriction set of the set of codebook restriction sets, and transmit, to the base station, a report indicating one or more precoding matrix indicators from the codebook for each of the one or more frequency-domain subbands based on the mapping.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, signaling may be impacted by Doppler shifts associated with communications between a user equipment (UE) and one or more devices in the system. To account for the Doppler shifts, the UE may receive a Doppler shift measurement configuration to use for estimating one or more Doppler shift parameters associated with one or more reference signals transmitted from the one or more transmission reception points (TRPs). The measurement configuration may include a measurement restriction parameter which indicates a number of durations that the UE may use to estimate the Doppler shift parameters. The UE may generate and transmit a measurement report for the estimated Doppler shift parameters according to a determined reporting accuracy and granularity.

Abstract: Certain aspects of the present disclosure provide methods for channel state information (CSI) reports transmitted on a multi-slot physical uplink shared channel (PUSCH). A method that may be performed by a user equipment (UE) includes receiving a grant triggering an aperiodic channel state information (A-CSI) transmission in a slot overlapping a scheduled transmission with slot aggregation of multiple PUSCH slots, determining CSI timing conditions based on a set of signals transmitted on only a subset of the multiple PUSCH slots, and sending A-CSI reports in one or more of the aggregated slots that satisfy the CSI timing conditions.
