Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may receive an announcement message from each sidelink anchor device of one or more sidelink anchor devices, wherein the announcement message includes a sidelink anchor device identifier and an indication that the sidelink anchor device is available for positioning services. The UE may measure the announcement message from each sidelink anchor device to determine a signal strength measurement associated with the sidelink anchor device. The UE may report, to a network node, one or more preferred sidelink anchor devices from the one or more sidelink anchor devices, wherein the one or more preferred sidelink anchor devices are determined based on the signal strength measurement respectively associated with each sidelink anchor device of the one or more sidelink anchor devices.

Abstract: A reference signal measurement method includes: receiving, at a user equipment from a transmission/reception point, a quasi co-location indication that indicates that a first signal, from the transmission/reception point and corresponding to a first radio access technology, is quasi co-located with a second signal from the transmission/reception point and corresponding to a second radio access technology that is different from the first radio access technology; receiving, at the user equipment from the transmission/reception point, the first signal and the second signal; and measuring, at the user equipment, the first signal based on the quasi co-location indication indicating that the first signal is quasi co-located with the second signal.

Abstract: In an aspect, a wireless node performs a first RSRP measurement of an RS-P based on a first set of samples within a first time window of an RS-P symbol or resource, and determines whether a spoofing attack is associated with RS-P based on the first RSRP measurement and one or more other RSRP measurements of one or more other sets of samples within one or more earlier time windows of the RS-P symbol or resource. The wireless node transmits, to a communications device (e.g., position estimation entity), an indication (e.g., in a measurement report) of the spoofing attack determination. The communications device performs at least one action based at least in part upon the indication of the spoofing attack determination.

Abstract: Aspects presented herein may enhance the efficiency and performance of RF sensing schemes/mechanisms based at least in part on time and frequency domain muting. In one aspect, a base station transmits, to a plurality of TRPs, a TRP configuration to configure the plurality of TRPs to transmit one or more RRSs over multiple transmission occasions based on a frequency band. The base station transmits, to the plurality of TRPs, an indication to mute at least one of a first sub-band or a second sub-band of the frequency band for transmitting the one or more RRSs in each of the multiple transmission occasions.

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.
