Abstract: Techniques for selecting a reference signal for positioning of a user equipment (UE) may comprise receiving a positioning reference signal (PRS) configuration that indicates a duration of time during which, for each of a plurality of PRS instances, the UE is to perform at least one respective measurement using at least one reference PRS resource. An indication that the UE is to provide a batch report indicative of the measurements also may be received. Performing the at least one respective measurement for each instance of the plurality of PRS instances may comprise selecting, from a plurality of candidate PRS resources, the at least one reference PRS resource based at least in part on a measured characteristic of the at least one reference PRS resource, or a received indication of the at least one reference PRS resource, or a combination thereof.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a network node performs a first measurement of a first reference signal resource, performs a second measurement of a second reference signal resource, determines, based on one or more consistency criteria, whether associating the first measurement and the second measurement with a same timing error group identifier (TEG-ID) indicates that a difference between a first timing error of the first measurement and a second timing error of the second measurement is less than a threshold, and reports, at least based on the determining, the first measurement and the second measurement in a batch measurement report, the first measurement and the second measurement associated with a first TEG-ID and a second TEG-ID, respectively.

Abstract: Described are methods, systems, and devices for processing a Positioning Reference Signal (PRS) or other reference signal usable for determining a position of a User Equipment (UE). In some aspects, a UE is configured to report to a network entity information indicating a number of receive (Rx) chains used to determine one or more positioning measurements, thereby indicating the amount of uncertainty in the positioning measurement(s) and the precision of a resulting position estimate. In some aspects, a UE is configured to receive multiple PRS signals that at least partially overlap in time and to process each PRS using a separate set of Rx chains to obtain positioning measurements. As part of the processing of a PRS, the UE may align a search window to the PRS. In this manner, different search windows can be maintained for different PRS signals to maximize the signal-to-noise ratio of each PRS.

Abstract: Aspects presented herein may enhance the accuracy and/or latency of UE positioning based on crowd-sourcing, where a network entity may compute a position estimate of a UE based on neighbor-cell scan data from the UE and one or more reference UEs. In one aspect, a network entity receives a first set of measurements associated with at least one cell from a UE. The network entity performs a position estimation of the UE based on at least one of the first set of measurements associated with the at least one cell, a second set of measurements for each of a set of reference UEs, or a location of each of the set of reference UEs via an ML model, where the UE and the set of reference UEs include at least one common cell.

Abstract: Disclosed are techniques for communication. In an aspect, a location server transmits a first request to at least a first network node, the first request including at least a first set of parameters indicating one or more first time instances during which the first network node is expected to perform and report one or more first positioning measurements of periodic positioning reference signals transmitted by a second network node during a plurality of periodic time instances, the plurality of periodic time instances including the one or more first time instances, and receives a first measurement report from the first network node, the first measurement report including the one or more first positioning measurements of the periodic positioning reference signals transmitted by the second network node during the one or more first time instances.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE transmits, at a first time during a measurement window for positioning purposes, a first uplink reference signal in accordance with a first timing adjustment parameter, wherein the first time is offset from a downlink frame time of a base station by an amount of the first timing adjustment parameter, determines whether to use a second timing adjustment parameter, transmits, in response to the determination to use the second timing adjustment parameter, at a second time during the measurement window, a second uplink reference signal in accordance with a second timing adjustment parameter, wherein the second time is offset from the downlink frame time of the base station by an amount of the second timing adjustment parameter, and transmits a report indicating that the second timing adjustment parameter has been applied to at least the second uplink reference signal.
