US 2026/0148073 A1 · COMMUNICATION FOR JOINT MEASUREMENT PROCEDURES

Abstract

Some procedures for collecting training data for artificial intelligence of machine learning (AI/ML) positioning may include collecting ground truth information from a user equipment (UE), and collecting radio frequency (RF) fingerprints between a UE and network nodes. An RF fingerprint may be information that characterizes an RF environment. Ground truth information may be radio access technology (RAT)-dependent (e.g., new radio (NR)-based positioning) or RAT-independent. To alleviate the burden on the amount of collected data with absolute ground truth information, semi-supervised techniques may be utilized, where the absolute ground truth location of UEs may be obtained for fewer locations or points. Some examples of the techniques described herein may provide procedures for collecting training data for one or more AI/ML positioning models. Some of the techniques may utilize device-to-device (D2D) positioning measurements, which may be used for training AI/ML models in a semi-supervised fashion.

Dependent claims

A first wireless device, comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the first wireless device to:
receive, from a network entity, configuration information indicating that the first wireless device is to participate in a joint measurement procedure, wherein the joint measurement procedure includes a radio frequency (RF) fingerprint measurement that is based at least in part on one or more first signals communicated between the first wireless device and one or more transmission-reception points (TRPs), and wherein the joint measurement procedure further includes a device-to-device (D2D) measurement that is based at least in part on a second signal communicated between the first wireless device and a second wireless device, wherein the RF fingerprint measurement is associated with the D2D measurement;
participate in communication of the one or more first signals with the one or more TRPs for the RF fingerprint measurement;
and
participate in communication of the second signal with the second wireless device for the D2D measurement, wherein the one or more first signals are communicated within a time limit from the second signal.
