Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives a set of antenna parameters for a plurality of antenna ports of a transmission-reception point (TRP), obtains positioning measurements of a plurality of positioning reference signal (PRS) resources transmitted on the plurality of antenna ports, reconstructs an underlying physical channel between the TRP and the UE based on the positioning measurements of the plurality of PRS resources, and determines a downlink angle of arrival (DL-AoD) measurement from the TRP to the UE based on the reconstructed underlying physical channel.

Abstract: In an aspect, an LMF component may determine to trigger positioning-related action(s) at a UE. The LMF component may request that a serving BS of the UE trigger the positioning-related action(s). The serving BS may transmit a DCI communication with a CSI request field (e.g., that triggers at least CSI reporting, or triggers positioning-related action(s) only). The CSI request field may further be associated with positioning-related information including at least one PRS configuration, at least one positioning measurement request, at least one location reporting request, or a combination thereof. The UE may perform the positioning-related action(s) based on the positioning-related information.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a radio frequency identification (RFID) station may receive a first packet from an RFID tag at a first arrival time. The RFID station may receive a second packet from the RFID tag at a second arrival time after the first arrival time. The RFID station may estimate a distance between the RFID station and the RFID tag based on an inter-packet arrival time between the first packet and the second packet, the inter-packet arrival time being based on a time difference between the first arrival time and the second arrival time.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a location server may receive measurement reports from one or more receiving radio frequency identification (RFID) stations, the measurement reports being based on a backscattered signal from an RFID device observed at the one or more receiving RFID stations, and the backscattered signal being based on a positioning reference signal transmitted by a user equipment (UE). The location server may determine an estimated position of the RFID device based on the measurement reports.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a receiver device receives, from a network entity, a request to report a power delay profile (PDP) similarity metric for a first positioning frequency layer on a first component carrier and a second positioning frequency layer on a second component carrier; determines a first PDP for a first reference signal received on the first positioning frequency layer and a second PDP for a second reference signal received on the second positioning frequency layer; determines the PDP similarity metric based on the first PDP and the second PDP; and transmits, to the network entity, the PDP similarity metric.

Abstract: A method of sending measurement information from a user equipment includes: measuring a reference signal; producing a measurement report payload based on measurement of the reference signal; encoding the measurement report payload in accordance with ASN.1 (Abstract Syntax Notation One) encoding, and in accordance with a lower-layer protocol to produce an encoded payload, the lower-layer protocol being either a physical-layer protocol or a MAC-layer (Medium Access Control layer) protocol; and sending a lower-layer message based on the encoded payload from the user equipment to a network entity.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) may send, to a network entity, information identifying a capability of the UE to process frequency modulated continuous wave (FMCW) signals. The UE may receive, from a network entity, information identifying a set of transmission / reception points (TRPs) for transmitting FMCW signals for a positioning measurement, the set comprising at least a first TRP and a second TRP. The UE may measure a first FMCW signal that was transmitted by the first TRP to produce a first frequency of arrival. The UE may measure a second FMCW signal that was transmitted by the second TRP to produce a second frequency of arrival. The UE may determine a location of the UE based on a frequency difference between the first frequency of arrival and the second frequency of arrival.

Abstract: Methods and apparatus for predicting wireless measurements based on virtual access points is described. In some embodiments, a location of a user equipment (UE) may be obtained, and given the location of the UE, an output may be generated using a machine learning model, the output including one or more predicted wireless measurements. The output may be indicative of a wireless channel in a multipath environment. In some variants, the machine learning model may have been trained by obtaining a training dataset comprising multipath components data and ground truth locations of a wireless device, and performing an optimization with respect to the multipath components data and the ground truth locations. In some implementations, a training output comprising a predicted multipath component may be produced during the training, and the optimization may include an iterative minimization of an error between at least the predicted multipath component and a labeled multipath component.
