Abstract: Disclosed are techniques for wireless communication. In an aspect, a first network node obtains one or more first positioning measurements of one or more reference signals transmitted by one or more second network nodes during a positioning session between a user equipment (UE) and a location server, and obtains one or more second positioning measurements of one or more backscattered signals of the one or more reference signals during the positioning session, wherein the one or more backscattered signals are transmitted by one or more ambient radio frequency identification (RFID) devices.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may obtain a first set of position estimates of the UE based on applying a first positioning model to one or more radio frequency fingerprint positioning (RFFP) measurements. The UE may obtain a second set of position estimates of the UE using a positioning technique that does not use the first positioning model. The UE may transmit a mismatch report, wherein the mismatch report is based on comparing the first set of position estimates with the second set of position estimates.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) transmits one or more provide capabilities messages to a location server, the one or more provide capabilities messages indicating at least a first set of capabilities of the UE to engage in a downlink radio frequency fingerprint (DL-RFFP) positioning procedure, and receives one or more positioning assistance data messages for the DL-RFFP positioning procedure from the location server, the one or more positioning assistance data messages based at least on the first set of capabilities.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity (e.g., UE, gNB, LMF, etc.) identifies a pool of UEs for a SL-assisted position estimation procedure of a set of target UEs. SL SRS-Ps are communicated (e.g., transmitted and measured) between the pool of UEs (e.g., for relative SL ranging). UL SRS-Ps are communicated by at least some of the UEs in the pool of UEs. The position estimation entity obtains measurement data for both the SL SRS-P and UL-SRS-P communications. The position estimation entity determines a position estimate for each UE in the set of UEs based on the measurement information.

Abstract: A wireless device may receive environment information associated with an area. The wireless device may simulate a set of positioning measurements based on the environment information. The wireless device may calculate a positioning environment based on the simulated set of positioning measurements. The wireless device may calculate the positioning environment further based on a set of measured positioning signals obtained by the wireless device. The wireless device may output the positioning environment to train a positioning model. The wireless device may output the positioning environment by training the positioning model at the wireless device based on the positioning environment. The wireless device may output the positioning environment by transmitting the positioning environment to a training entity to train the positioning model.

Abstract: A user equipment (UE) may define the classes of a plurality of path delay detection algorithms that the UE may use to identify line-of-sight positioning signals and reject non-line-of-sight positioning signals. The UE may receive a capabilities request from a location server and transmit, to the location server, a capability report indicating the classes of the plurality of path delay detection algorithms supported by the UE. The UE receives a location information request from a location server, and selects a path delay detection algorithm, which is used to perform measurements of one or more positioning signals received by the UE. The UE provides an indication of the selected path delay detection algorithm along with the positioning measurements to the location server. The location server determines or verifies a location of the UE based on the path delay detection algorithm selected by the UE and the positioning measurements.

Abstract: A signal measurement assistance method includes: obtaining reference signal angle information comprising first indications indicating a first reference signal and a first expected angle of arrival of the first reference signal; and at least one of: requesting a transmission/reception point (TRP) to transmit, to a user equipment, the first indications; or requesting the TRP to search for the first reference signal based on the first expected angle of arrival.

Abstract: A user equipment includes a processor configured to: receive a first, second, and third reference signals including a first, second, and third sets of tones, and spanning first, second, and third frequency ranges in first and second sets of symbols and at least one third symbol, respectively, the first and second frequency ranges differing: where at least one of (1) the third frequency range overlaps the first frequency range, or (2) the at least one third symbol overlaps with the first set of symbols and the third frequency range overlaps the second frequency range; determine an offset between the first reference signal and the supplemental signal using the third set of tones; and determine a first indication, of a time and/or a range, based on a combination of the first reference signal and the second reference signal using the offset.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a communication device may receive a reference signal from a communication station, wherein the reference signal is based on a reference component carrier. The communication device may generate one or more control signals based on one or more keying signals, the one or more keying signals having respective one or more keying frequencies. The communication device may transmit a backscattered signal based on the reference signal and the one or more control signals, wherein the backscattered signal is based on one or more pairs of component carriers that correspond to the reference component carrier shifted by the one or more keying frequencies.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a radio frequency identification (RFID) device receives, from an RFID tag, a first backscattered signal, receives, from the RFID tag, a second backscattered signal having a known time offset relative to the first backscattered signal, and performs interference cancellation on the first backscattered signal based on the second backscattered signal.
