Abstract: In an aspect, a location of a reference UE is obtained (e.g., iteratively). A first differential RTT measurement is determined based on RTTs between a target UE and each of first and second wireless nodes, and a second differential RTT measurement is determined based on RTTs between a reference UE and each of the first and second wireless nodes. A positioning estimate of the target UE is determined based on the first and second differential RTT measurements and the obtained reference UE location (e.g., a most recent of the iteratively obtained reference UE locations). In another aspect, a primary reference UE among a plurality of reference UEs is selected, and its location is obtained (e.g., iteratively). A location of other reference UE(s) is determined based at least in part upon the obtained primary reference UE location (e.g., a most recent of the iteratively obtained primary reference UE locations).

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process may include receiving, at a network device (e.g., a user equipment (UE)) from a network entity via a number of sensing streams based on a maximum of Nt-J sensing streams, a waveform including communications resources and sensing resources. The waveform has a rank Nt and J is a number of layers scheduled for multiple-input multiple-output (MIMO) communications that is less than Nt. The process may further include processing at least the communications resources of the waveform.

Abstract: Disclosed are techniques for wireless communication, and specifically for reconfigurable intelligent surface (RIS)-aided positioning. In some aspects, a base station (BS) may transmit, to a user equipment (UE), a first positioning reference signal (PRS). The BS may transmit, to RIS configured to reflect a received signal towards the UE, a second PRS. The BS may receive, from the UE, a downlink reference signal time difference (RSTD) measurement for the first PRS and the second PRS.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a base station determines a channel profile for a multipath channel between the base station and a user equipment (UE) based on at least one positioning reference signal transmitted to the UE or received from the UE by the base station on one or more radio beams, compresses the channel profile into a compressed representation of the channel profile, and transmits the compressed representation of the channel profile to a network entity. The network entity receives the compressed representation of the time-angle channel profile and determines a location of the UE based on the compressed representation of the channel profile.

Abstract: Techniques for a high-accuracy determination the position of a light user equipment (UE) using a single base station are presented. This is accomplished by leveraging communications with a premium UE having a known location relative to the base station. Wireless reference signals measured by the light UE and premium UE, along with a reference signal from the light UE to the premium UE, can be used to determine the position of the light UE geometrically. The determination can be made by the light UE, premium UE, or a location server, depending on desired functionality.

Abstract: Techniques are provided for utilizing positioning reference signals (PRS) in full duplex scenarios. An example method for wireless communication by a user equipment (UE) includes receiving a positioning reference signal in a time slot, wherein the positioning reference signal spans a first frequency bandwidth, transmitting a signal in a second frequency bandwidth during the time slot, wherein the second frequency bandwidth includes frequencies within the first frequency bandwidth, and processing the positioning reference signal received in the first frequency bandwidth excluding the frequencies in the second frequency bandwidth.
