    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: 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: In an aspect, a method of wireless communication performed by a user equipment (UE) includes measuring a plurality of different bandwidth segments of a reference signal (RS) over a corresponding plurality of different RS occasions during a positioning session to obtain a plurality of radio frequency fingerprint positioning (RFFP) measurements corresponding to the plurality of different bandwidth segments; aggregating the plurality of RFFP measurements to provide at least one aggregated RFFP measurement; and applying a positioning model to the at least one aggregated RFFP measurement to obtain an estimate of one or more positioning parameters associated with a location of the UE.
