Abstract: Methods and apparatus for resource allocation for radio frequency (RF) sensing signals in data communications systems are provided. In some embodiments, a transmitter may determine one or more capabilities associated with a multiple input, multiple output (MIMO) antenna of the transmitter, send information relating to the capabilities to a network entity (e.g., server) of the network, obtain configuration data relating to an allocation of frequency resources for a RF sensing signal (e.g., radar reference signal) interleaved with respect to a plurality of antenna ports associated with the MIMO antenna, and transmit the RF sensing signal in accordance with the configuration data. The obtained data may be configured based on the capabilities. The frequency resources may be orthogonal frequency-division multiplexing (OFDM) resources. According to different embodiments, allocation of OFDM resources may be equidistant, non-equidistant, or on demand (e.g., as requested by the server or confirmed by the server).

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a reduced- capability user equipment (UE) receives, from each of one or more premium UEs, one or more parameters indicating a quality of a location estimate of the premium UE, selects at least one premium UE based on the quality of the location estimate of the at least one premium UE, and derives a location estimate of the reduced-capability UE based on the location estimate of the at least one premium UE. In another aspect, a reduced-capability UE transmits, to at least one premium UE, a request to perform one or more positioning measurements of one or more downlink reference signals, receives, from the at least one premium UE, a measurement report comprising the one or more positioning measurements, and determines a location estimate of the reduced-capability UE based on the one or more positioning measurements in the measurement report.

Abstract: Disclosed are techniques for communication. In an aspect, a network component determines location assistance data comprising information associated with one or more reconfigurable intelligent surfaces (RISs). The network component transmits, to a user equipment (UE), the location assistance data to facilitate one or more location procedures based on the location assistance data. The UE receives the location assistance data and performs the one or more location procedures based on the location assistance data.

Abstract: A first wireless node may output a configuration of a plurality of reference signals (RSs) based on a set of sensing measurement conditions. The sensing measurement conditions may include one or more of a range resolution, a maximum range, a velocity resolution, a maximum velocity, a velocity range, an angle of arrival (AoA) measurement, an angle of departure (AoD) measurement, or a multiple-input multiple-output (MIMO) sensing occasion for radar sensing. A second wireless node may obtain the configuration of the plurality of RSs. The first wireless node may transmit the plurality of RSs for the radar sensing based on the configuration. The second wireless node may receive the plurality of RSs for the radar sensing based on the configuration. The second wireless node may perform the radar sensing based on the received plurality of RSs.

Abstract: Disclosed are systems, methods, and non-transitory media for detecting a positioning attack based on wireless position signaling. For example, a location server can determine a positioning reference signal having at least a first signal portion and at least a second signal portion. An indication of a positioning attack associated with the positioning reference signal can be obtained. The location server can provide, to a base station, a message of transmission preemption of the second signal portion of the positioning reference signal based on the indication of the positioning attack.
