Abstract: Aspects described herein relate to receiving a configuration for cross-link interference (CLI) measurement reporting, wherein the configuration includes, for each component carrier of one or more component carriers, one or more parameters for measuring signals on the component carrier, and a resource setting indicating resources of the component carrier over which to measure signals. One or more measurements of signals received on the resources indicated by the resource setting for the component carrier can be measured based at least in part on the one or more parameters, and reported to a base station.

Abstract: Certain aspects of the present disclosure provide techniques for efficient signaling of frequency resources in multiple cells. For example, a single downlink control information (DCI) transmission to a user equipment (UE) may be used to indicate a bandwidth part (BWP) switch to be applied in multiple cells. In some cases, the BWP switch may be into a pre-defined BWP across the multiple cells (and the same DCI may also schedule or trigger data or reference signals in the pre-defined BWP).

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques at a user equipment (UE) provide for efficiently reporting channel state information (CSI) to a base station with an appropriate level of accuracy. In particular, the base station may indicate a level of accuracy to the UE for reporting CSI. The UE may encode the CSI using a first neural network, and the base station may decode the CSI using a second neural network. The first and second neural networks may form a neural network pair, and the UE may train the neural network pair based on the level of accuracy indicated by the base station. For example, the base station may indicate a loss function corresponding to a level of accuracy with which CSI is to be reported by the UE, and the UE may train the neural network pair using the loss function.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for providing channel state feedback. One example method generally includes receiving at least one first pilot signal, and generating a first channel state information (CSI) report based on the at least one first pilot signal. The first CSI report may include a differential phase feedback for each subband (SB) of one or more SBs associated with the at least one first pilot signal. The method may also include transmitting the first CSI report having the differential phase feedback.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for sounding reference signal (SRS) guided downlink channel state information-reference signal (CSI-RS) scan. One example method for wireless communication generally includes determining whether to perform channel measurement and reporting operations for a user-equipment (UE) using a reciprocity-based scheme or a channel state information-reference signal (CSI-RS) based scheme based on a criteria of a cell, and performing the channel measurement and reporting operations based on the determination

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine that a user equipment (UE) is to use a differential reporting mode based at least in part on a channel state information (CSI) report from the UE. The base station may transmit to the UE, signaling to cause the UE to use the differential reporting mode based at least in part on determining that the UE is to use the differential reporting mode. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a signaling communication that includes information specifying whether a channel state information reference signal (CSI-RS) precoding resource block group includes a same quantity of resource blocks (RBs) that is included in a CSI reporting subband configured for the UE. The CSI-RS precoding resource block group may enable the UE to perform a channel estimation based at least in part on a CSI-RS transmitted by a base station. The UE may perform the channel estimation based at least in part on the CSI-RS transmitted by the base station. The channel estimation may be based at least in part on whether the CSI-RS precoding resource block group includes the same quantity of RBs that is included in the CSI reporting subband configured for the UE. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for uplink sounding reference signal (SRS) transmission with precoding. A method for wireless communication by a user equipment (UE) includes receiving a SRS configuration that configures one or more SRS resource sets, each resource set including one or more SRS resources, each SRS resource comprising one or more SRS ports. The UE receives a set of precoders via an indicator, the set of precoders including a precoder associated with each SRS resource and determines one or more precoders to apply for one or more SRS transmissions via one or more of the SRS resources.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, such as a user equipment (UE) may receive an allocation of a set of sensing resources and a set of cross-link interference measurement resources. The UE may identify a sensing resource of the set of sensing resources on which a sensing signal is received, and determine one or more of the set of cross-link interference measurement resources that overlap with the sensing resource. The UE may thereby measure the one or more cross-link interference measurement resources for cross-link interference based on the one or more cross-link interference measurement resources overlapping with the sensing resource.
