    Abstract: Aspects of the present disclosure relate to wireless communication. In some aspects, a user equipment may determine at least one of: a first number of coefficients to be included in a first set of coefficients in a transfer domain that characterize compressed channel state information (CSI) for a first layer, or a first quantization scheme to be used to interpret the first set of coefficients. The UE may determine at least one of: a second number of coefficients to be included in a second set of coefficients in the transfer domain that characterize the compressed CSI for a second layer, or a second quantization scheme to be used to interpret the second set of coefficients. The UE may transmit a report that identifies the first set of coefficients and the second set of coefficients based at least in part on the determination(s). Other aspects are provided.

    Abstract: Methods, systems, and devices for wireless communications are described. A example method for wireless communication at a reconfigurable reflective surface comprises receiving one or more signals from a first wireless device and determining, based at least in part on the one or more signals, measurement information pertaining to a wireless channel between the reconfigurable reflective surface and the first wireless device. The example method may further include determining, based at least in part on the measurement information, a set of weights for a plurality of reflective elements of the reconfigurable reflective surface to be used in reflecting communications between the first wireless device and a second wireless device.

    Abstract: Methods, systems, and devices for wireless communication are described. A first wireless device may transmit one or more signals to a second wireless device using an antenna panel including antenna elements that are arranged in a hexagonal configuration. The signals may be transmitted using one or more directional beams for multiple-input multiple-output communications with the second wireless device, the directional beams generated based on the antenna elements in the hexagonal configuration. The first wireless device may receive a signal from the second wireless device, and in some cases, the first wireless device may transmit one or more reference signals via the one or more directional beams, the reference signals associated with a set of two or more antenna elements of the antenna panel of the first wireless device. The second wireless device may perform measurements of the reference signals and transmit a measurement report to the first wireless device.

    Abstract: Methods, systems, and devices for wireless communications are described. For instance, a first wireless device may receive, from a controller of a reconfigurable surface, an indication of a capability of the controller of the reconfigurable surface to perform one or more operations associated with communications between the controller and the first wireless device. The first wireless device may communicate first information with the controller of the reconfigurable surface based on receiving the indication of the capability and may communicate with a second wireless device via the reconfigurable surface, where an adjustment for the reconfigurable surface for communicating with the second wireless device is based on the first information.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform measurements of a first plurality of interference measurement resources on a channel from a reconfigurable intelligent surface (RIS) to the UE. The first plurality of interference measurement resources are associated with a plurality of beams. Accordingly, the UE may transmit a first report based at least in part on the measurements of the first plurality of interference measurement resources. The UE may additionally perform measurements of a second plurality of interference measurement resources on the channel from the RIS to the UE. The second plurality of interference measurement resources are associated with a plurality of phases. Accordingly, the UE may transmit a second report based at least in part on the measurements of the second plurality of interference measurement resources. Numerous other aspects are described.

    Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure provide techniques for uplink channel state information (CSI) reporting that supports transmission precoding matrix indicator (TPMI) selection. A user equipment (UE) may receive CSI reference signals (CSI-RSs), and may perform measurements on the CSI-RSs. The UE may transmit an uplink CSI report to a base station based on the measurements. The CSI report may include an indication of a set of one or more candidate TPMIs, rank indicators (RIs), or both. The base station may test the candidate TPMIs, one or more other TPMIs, or both, to received sounding reference signals (SRSs) and select a TPMI for subsequent signaling. The base station may transmit an uplink grant (e.g., via downlink control information (DCI)) indicating the selected TPMI. The DCI may be a single-stage DCI a timeline.
