    Abstract: An example aspect comprises selecting an azimuth mode for an OAM MIMO transmission by a transmitter that includes a first number of circles that each include a second number of antenna elements, wherein the azimuth mode defines a DFT vector of a size less than or equal to the second number; selecting, from a plurality of radial modes associated with the azimuth mode, a radial mode for the transmission, wherein the radial modes include at least a first radial mode defining a first beamforming vector and a second radial mode defining a second beamforming vector, wherein each one of the first and second beamforming vectors includes the DFT vector weighted and repeated for a number of times less than or equal to the first number, wherein the first and second beamforming vectors are orthogonal to each other; and transmitting a signal using a beam configured according to the radial mode.

    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.

    CPC classification number: H04W8/22 H04L5/0051 H04W72/231

    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: 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.
