Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration identifying a first set of frequency resources for transmitting a sounding reference signal, where the sounding reference signal may be used at least for downlink channel state information acquisition. The UE may receive an indication of an association between the configuration for the sounding reference signal and a second set of frequency resources and determine, based on the association, values for one or more sounding reference signal transmission parameters for the first set of frequency resources. The UE may transmit the sounding reference signal on the first set of frequency resources based on the determined one or more values.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a pre-emption indication associated with a scheduled transmission between the base station and the UE. Accordingly, the UE may perform energy harvesting, during the scheduled transmission, based at least in part on the pre-emption indication. 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 receive a cell-level cross link interference sounding reference signal (CLI-SRS) configuration, wherein the cell-level CLI-SRS configuration identifies CLI-SRS resources in one or more full-duplex slots for cross link interference measurements associated with Uu and sidelink communications. The UE may receive an indication to transmit a CLI-SRS, or to measure cross link interference, in a CLI-SRS resource of the CLI-SRS resources identified in the cell-level CLI-SRS configuration. The UE may transmit the CLI-SRS in the CLI-SRS resource or measuring cross-link interference in connection with a CLI-SRS transmission from another UE in the CLI-SRS resource based at least in part on the indication. Numerous other aspects are described.

Abstract: Techniques are provided for utilizing positioning reference signals (PRS) in full duplex scenarios. An example method of providing positioning information for a mobile device to a base station includes receiving, at the mobile device, a positioning request and an accuracy requirement from the base station, determining one or more positioning reference signal transmissions based on the accuracy requirement, obtaining position measurement information based on the one or more positioning reference signal transmissions, and providing the position measurement information to the base station.

Abstract: Methods, systems, and devices for wireless communications are described that support virtual resource block (RB) to physical RB mapping in duplex slots. The described techniques enable a user equipment (UE) to select an interleaving configuration such as a full duplex or half duplex interleaving configuration for a slot that may be configured for full duplex communications. In some cases, the UE may use a default interleaving configuration for a given slot or may determine the interleaving configuration based on a bandwidth part (BWP) position or resource bandwidth within the slot, such as a location within the frequency domain of a downlink BWP relative to an uplink BWP.

Abstract: In a wireless network, a base station may configure a victim user equipment (UE) experiencing interference with a periodic measurement resource using Layer 3 (L3) signaling, and the UE may report cross-link interference (CLI) measurements to the base station using L3 messages. However, using L3 signaling to configure interference measurement and reporting may result in an inflexible interference measurement configuration and a long latency to report CLI and/or self-interference feedback. Furthermore, although Layer 1 and/or Layer 2 (L1/L2) CLI reporting may be more suitable to track and adapt to dynamic changes in interference conditions, L1/L2 signaling increases control signaling and CLI management overhead at the base station. Accordingly, some aspects described herein relate to an adaptive L3 CLI measurement and reporting framework, where L3 messages may include one or more adaptive fields to support flexibility in configuring CLI measurement and/or CLI reporting parameters.
