Abstract: A network node supports position measurement determination for a user equipment (UE) by prioritizing positioning reference signal (PRS) resource measurements to be included in a location information report based on multipath characteristics of the PRS resources. The network node, for example, may be the UE, a base station, or a sidelink UE. The PRS resource measurements may be prioritized by determining a subset of available PRS resource measurements to include in and/or the order of inclusion in the location information report. The multipath characteristics of each PRS resource may be the number, a strength metric, or a time domain span of the multipath components, or any combination thereof. A location server may request the prioritization of the PRS resource measurements based on the multipath characteristics of the PRS resources and may use the order of the PRS resource measurements in the position determination for the UE.

Abstract: Techniques are discussed herein for prioritizing and reporting reference signal measurements relative to a time window. An example method for measuring positioning reference signals includes obtaining positioning reference signal configuration information, obtaining preferred measurement reporting window information, determining priority values for a plurality of positioning reference signals, wherein each priority value for a respective positioning reference signal is based at least in part on the positioning reference signal configuration information and the preferred measurement reporting window information, and reporting measurement values for one or more of the plurality of positioning reference signals based on the priority value.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a first network node performs a reception-to-transmission (Rx-Tx) time difference measurement, the Rx-Tx time difference measurement representing a difference between a reception time of at least one first positioning reference signal (PRS) from a second network node and a transmission time of at least one second PRS to the second network node, and transmits, to a positioning entity, based on a value of the Rx-Tx time difference measurement being greater than a threshold, a measurement report including a first value and a second value representing the value of the Rx-Tx time difference measurement, wherein the first value is a quotient value resulting from dividing the value of the Rx-Tx time difference measurement by the threshold, and wherein the second value is a remainder value resulting from dividing the value of the Rx-Tx time difference measurement by the threshold.

Abstract: In an aspect, a target user equipment (UE) receives discovery messages from peer UEs. Each discovery message indicates a subset of capabilities associated with a peer UE to participate in a sidelink positioning session. The target UE sends an interest message to the peer UEs indicating that the target UE intends to have the peer UEs participate in the sidelink positioning session and receives capability messages from the peer UEs indicating additional capabilities associated with each of the peer UEs. The target UE sends a selection message to at least one peer UE to participate in the sidelink positioning session based on the subset of capabilities and the additional capabilities associated with the at least one peer UE. The selection message requests the at least one peer UE participate in the sidelink positioning session with the target UE.

Abstract: In an aspect, a method performed by a network node includes obtaining a first plurality of radio frequency fingerprint positioning (RFFP) measurements corresponding to a plurality of known displacements between positions of a user equipment (UE); and training a positioning model to provide a position estimate of the UE, wherein the training of the positioning model is at least based on the first plurality of RFFP measurements and the known displacements between the positions of the UE corresponding to the first plurality of RFFP measurements.

Abstract: Wireless communications systems and methods related to narrow beam-based channel access for communications in a wireless communication network operating over an unlicensed spectrum are provided. A first wireless communication device receives, from a second wireless communication device, one or more signals associated with a beam parameter. The first wireless communication device determines, at each of a plurality of locations, a signal measurement for at least one received signal of the one or more received signals. The first wireless communication device determines, based at least in part on an p-th percentile signal measurement and a q-th percentile signal measurement of the signal measurements at the plurality of locations, whether the second wireless communication device satisfies an interference condition.

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: A user equipment (UE) obtains assistance data for positioning from one or more sidelink connected UEs. Prior to sending the assistance data for positioning to the UE, the sidelink UE(s) revises the assistance data, e.g., by reprioritizing, reordering, or reducing the assistance data, or a combination thereof. By revising the assistance data the sidelink UE(s) provides the most pertinent assistance data to the UE, thereby increasing power savings for the UE. Where multiple sidelink UEs provide revised assistance data to the UE, the UE combines the revised assistance data, e.g., based on measurement information, range information, or priority of the sidelink UEs. If the UE has a connection to the location server, the UE obtains revised assistance data from sidelink UE(s) to avoid the need for an assistance data exchange with the location server during the positioning session, thereby improving latency.

Abstract: Disclosed are systems, apparatuses, methods, and non-transitory media for facilitating positioning reference signal (PRS) prioritization by receiving beam index information associated with a PRS beam set. In some aspects, an assigned beam can be determined based on the beam index information. At least one adjacent beam can further be determined to be based on the assigned beam associated with the beam index information. A location measurement can also be determined based on at least one of the assigned beam, or the at least one adjacent beam.
