Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an indication of a plurality of beams received by the UE. The UE may receive a message indicating at least a first resource set associated with one or more first beams from the plurality of beams and a second resource set associated with one or more second beams from the plurality of beams. The UE may transmit a report indicative of a level of correlation between pairs of individual beams, each pair including a first individual beam of the one or more first beams and a second individual beam of the one or more second beams, and the UE may communicate with the base station via a selected beam of the one or more first beams or the one or more second beams.

Abstract: Methods, apparatuses, and computer-readable medium for configuring a reconfigurable intelligent surface (RIS) are provided. An example method may include receiving, from a second wireless device through a RIS, a set of reference signals (RSs) mapped to a set of single port resources, the set of single port resources being quasi-co-located (QCLed) and time division multiplexed (TDMed). The example method may further include transmitting, to the second wireless device through the RIS, a set of measurement results based on the set of RSs, the set of measurement results being mapped to a set of surface configurations of the RIS.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a transmission configuration state for receiving downlink channel transmissions from a base station via a configurable surface. The transmission configuration state may indicate a quasi-co-location source associated with transmission via the configurable surface. The UE may receive a downlink channel transmission via the configurable surface based on the transmission configuration state and the quasi-co-location source. The UE may be capable of determining whether the transmission configuration state conflicts with the quasi-co-location source indicated by the transmission configuration state. The UE may transmit an indication to the base station that the configuration for the transmission configuration state conflicts with the quasi-co-location source. The indication may include a beam failure indication or a measurement report. The UE may fall back to a transmission configuration state previously activated at the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver of a holographic multiple input multiple output (MIMO) communication may receive, using at least one receive antenna element, a plurality of reference signals associated with at least one transmit antenna element of a transmitter of the holographic MIMO communication. The receiver may communicate using two-dimensional beams or three-dimensional beams based at least in part on a determination of a beam format associated with the plurality of reference signals. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for precoder matrix quantization for compressed channel state information (CSI) feedback. A method for wireless communications by a user equipment (UE) includes receiving a CSI report configuration for frequency domain compressed precoder matrix feedback. The CSI report configuration configures the UE to report, for a plurality of selected beams at a plurality of time domain taps, a frequency domain compression basis vector and a plurality of linear combination coefficients associated with the frequency domain compression. For each of the beams, the UE groups the time domain taps into at least first and second groups. The groups each can have zero, one, or more than one time domain taps. The UE quantizes the corresponding linear combination coefficients and/or frequency domain compression basis vectors based on the grouping.

Abstract: Techniques for channel state feedback using sensing reference signals are disclosed. The techniques can include identifying a channel state information (CSI) report configuration based on CSI reporting configuration information received from a radio access network (RAN) node of a RAN, based on the CSI report configuration, identifying a set of basis reference signals to be measured on a wireless channel of the RAN, wherein the set of basis reference signals includes one or more sensing reference signals, measuring the set of basis reference signals to obtain channel state measurements, determining channel state information based on the channel state measurements, and transmitting a CSI report including the channel state information to the RAN node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network, a list of serving cells including a first serving cell that is using a control resource set (CORESET) for single frequency network (SFN) transmissions. Additionally, the UE may receive, from the network, a control element indicating two transmission configuration indicator (TCI) states and associated with the first serving cell and the CORESET. Accordingly, the UE may process the control element based at least in part on determining that one or more additional serving cells in the list are not using the CORESET for SFN transmissions. Numerous other aspects are described.

Abstract: A victim user equipment (UE) may experience cross-link interference (CLI) from transmissions from an aggressor UE. The present disclosure provides for configuration of a CLI report that accurately characterizes the CLI experienced by the victim UE. A base station may transmit to the victim UE, a configuration for CLI reporting associated with one or more channel state information interference measurement (CSI-IM) resources. The victim UE may generate a CLI report based on the configuration for CLI reporting and the CSI-IM resources. The victim UE may transmit the CLI report to the base station. The base station may use the CLI report to mitigate the CLI, for example, by scheduling the aggressor UE and the victim UE to reduce CLI experienced by the victim UE.

Abstract: A user equipment (UE) may be configured to transmit sounding reference signals to sound over ports of a channel. The UE may be configured to receive a message to trigger transmission of at least one sounding reference signal (SRS) of at least one SRS resource set for sounding over an active bandwidth part (BWP) in an upcoming slot, the upcoming slot being offset by a number of available slots from a reference slot indicated by the message. The UE may be further configured to detect a gap in which operation for the active BWP is suspended occurring before the transmission of the at least one SRS of the at least one SRS resource set is complete.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE receives first signaling triggering the UE to transmit a base channel state information (CSI) report to a network entity. The UE transmits the base CSI report to the network entity in response to the first signaling. The UE takes action to reduce or avoid error propagation when transmitting one or more differential CSI reports that include at least some CSI values reported relative to CSI values in the base CSI report.
