Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first device (310) may receive multiple reference signals (RSs) from a second device (320) via a plurality of passive devices (410,420), where each RS of the multiple RSs is forwarded individually by one of the plurality of passive devices with a first set of reflection configurations (Slot 502, Slot 504). The first device may receive an additional RS from the second device via the plurality of passive devices, where the additional RS is forwarded jointly by all of the plurality of passive devices with a second set of reflection configurations (Slot 506). The first device may determine information from the plurality of passive devices based on the multiple RSs and the additional RS, where the information is represented by a change between the first set of reflection configurations and the second set of reflection configurations. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described in which a transmitting device may transmit a set of reference signals to a receiver via a configurable surface such as a reconfigurable intelligent surface (RIS). The RIS may randomly adjust one or more parameters for one or multiple RIS elements to provide different beamformed parameters for reflected instances of each reference signal from the RIS. Each reference signal may have a corresponding reference signal index value, and the receiver may provide an indication of a selected the reference signal index value based on channel measurements of the reference signals. The transmitting device may provide an indication to the RIS of the index value, and may communicate with the receiver based on the selected reference signal via the RIS, where the RIS uses the parameters associated with the RIS index value for the communications.

Abstract: A method for wireless communication performed at a user equipment (UE) includes receiving, from a base station, an indication that the base station supports data-aware precoding. The method also includes transmitting, to the base station based on the base station supporting data-aware precoding, an indication that the UE supports the data-aware precoding and an indication of data-aware precoding capabilities of the UE. The method also includes receiving, from the base station, a current precoding mode indicator identifying a current precoding mode for precoding one or more resource elements of one or more subcarriers at the base station. The method further includes receiving, from the base station, a data transmission on a data channel, both the data transmission and the data channel precoded based on the current precoding mode. The method still further includes decoding the data transmission and the data channel based on the current precoding mode.

Abstract: Techniques for configuring reconfigurable intelligent surfaces serving full-duplex nodes are provided. In an example, a first network node such as a base station or a user equipment (UE) may determine to communicate with a second network node (e.g., UE or base station) via a reconfigurable intelligent surface (RIS) system using full-duplex communications. The first network node may transmit, to an RIS controller of the RIS system, an indication that the first network node will communicate with the second network node using the full-duplex communications.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive signaling that schedules a shared channel and indicates a set of demodulation reference signal (DMRS) ports scheduled for the UE, the signaling including a field for conveying an indicator of a co-scheduled UE for the set of DMRS ports. The UE may communicate a set of DMRSs based at least in part on the signaling. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for configuring a reconfigurable intelligent surface (RIS) for wireless communication. A method that may be performed by a base station (BS) includes transmitting one or more parameters corresponding to a time period for the RIS to adapt to user equipment (UE) configuration information, the UE configuration information for configuring the RIS for RIS-assisted communication between the BS and a UE, the one or more parameters comprising a number of symbols indicative of a duration of time. The method also includes transmitting, via the RIS and separately from transmitting the one or more parameters, a control channel to the UE scheduling communication of a data channel with the UE via the RIS. The method also includes communicating, via the RIS, the data channel with the UE the duration of time after transmitting the control channel to the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first indication of a first number of antenna ports for which the UE is to report channel state information (CSI), and a second indication of a second number of antenna ports on which the UE is to measure CSI reference signals (CSI-RSs). The second number may be less than the first number. The UE may receive an indication of one or more antenna port parameters, where each may be associated with one of the first number of antenna ports or the second number of antenna ports. The UE may determine the CSI for the first number of antenna ports using the one or more antenna port parameters and measurements made by the UE on the second number of ports, and may transmit a report including the CSI for the first number of ports.
