    Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may obtain configuration information that identifies resources for sounding reference signal (SRS) positioning. The UE may transmit, to a reconfigurable intelligent surface (RIS), a plurality of SRS transmissions at different times according to the configuration information. The UE may receive, from the RIS, a plurality of SRS transmissions comprising reflections of the plurality of SRS transmissions to the RIS, wherein each of the plurality of SRS transmissions from the RIS is transmitted at a different angle of departure (AoD) from the RIS. The UE may measure each of the plurality of SRS transmissions from the RIS to produce a plurality of measurements. The UE may perform a positioning operation based on the plurality of measurements.

    Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may receive, from a serving base station, a first round-trip time (RTT) measurement signal. The UE may send, to the serving base station, a second RTT measurement signal. The UE may send, to at least one other UE, a third RTT measurement signal. The UE may send, to the serving base station or to a location server, an indication of a first delay between receiving the first RTT measurement signal and sending the second RTT measurement signal and an indication of a second delay between sending the second RTT measurement signal and sending the third RTT measurement signal.

    Abstract: A determination of a position of a target mobile device in a wireless communication network employing time-division duplexing (TDD) can use a wireless reference signal from another mobile device with a known position. The other mobile device can be configured to transmit the wireless reference signal using cross-link interference (CLI), where the target mobile device receives the signal during a period in which the target mobile device is configured to receive downlink (DL) communication. The target mobile device then transmits another wireless reference signal, which is received by a base station, which also receives the wireless reference signal from the other mobile device. The timing of these various signals received at the target mobile device and base station can be used to determine the location of the mobile device.

    Abstract: Aspects presented may enable RF sensing to be adaptive to the environment to improve the sensing, performance, and/or the spectrum efficiency of cellular systems and the power efficiency of RF sensing nodes. In one aspect, an RF sensing node extracts one or more features for a set of objects of an area via at least one non-RF sensor. The RF sensing node transmits, to a network entity, the one or more features or at least one non-RF measurement derived from the one or more features. The RF sensing node receives, from the network entity, an RRS transmission configuration derived based on the one or more features or the at least one non-RF measurement transmitted to the network entity.

    Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process includes receiving a signal comprising a slot including at least one shared signal resource. The process further includes determining whether the slot is allocated for sensing and communications or is allocated for communications. The process further includes determining whether to demodulate the at least one shared signal resource using at least one sensing reference signal (RS) resource or at least one communication RS based whether the slot is allocated for sensing and communications or is allocated for communications.

    Abstract: A signal reporting method includes: transmitting, from a first wireless signaling device at a first time, a first PRS (positioning reference signal) to a second wireless signaling device via a first RIS (reconfigurable intelligent surface); receiving, at the first wireless signaling device at a second time, a second PRS from the second wireless signaling device via a second RIS that is physically separate from the first RIS; and providing a signal report including at least one time value corresponding to the first time and the second time, and indicative of the first PRS and the second PRS.

    Abstract: Aspects presented herein may improve the performance and accuracy of a UE positioning based on RIS, such as when the RIS has a limited number of control voltage sets available. In one aspect, a UE obtains an indication of beam pattern information for a set of DL beams for a network entity, where the set of DL beams is associated with an RIS. The UE adjusts a first transmission angle for a set of UL beams based on the beam pattern information and measurement for the set of DL beams, where the first transmission angle for the set of UL beams is adjusted to proximately align with a second transmission angle of the set of DL beams from the RIS. The UE transmits, via the RIS, the set of UL beams to the network entity based on the adjusted first transmission angle.
