Abstract
Systems, methods, and/or apparatuses are provided herein for positioning devices in a network using estimated measurements. A wireless transmit/receive unit (WTRU) may determine positioning accuracy based on one or more actual and/or inferred measurements. The WTRU or a network entity may train and/or implement one or more artificial intelligence (AI) and/or machine learning (ML) models to determine the positioning accuracy.
Claims21
-20. (canceled)
A wireless transmit/receive unit (WTRU) comprising:
- a processor configured to:
- receive configuration information, wherein the configuration indicates positioning reference signal (PRS) configuration information for each of a plurality of transmission/reception points (TRPs), wherein the configuration information indicates one or more criteria for requesting PRS measurement assistance information, and wherein the configuration information indicates a minimum number of TRPs for which one or more PRS measurements are to be reported;
- determine that at least one criteria of the one or more criteria for requesting the PRS measurement assistance information is satisfied based on one or more measurements performed on one or more of the plurality of TRPs;
- send a request for the PRS measurement assistance information, wherein the request indicates a location of the WTRU that is determined based on the one or more measurements performed on one or more of the plurality of TRPs;
- receive the PRS measurement assistance information, the PRS measurement assistance information comprising one or more artificial intelligence/machine learning (AI/ML) model parameters;
- estimate one or more measurements for at least one TRP based on the one or more AI/ML model parameters and at least one measurement performed using the PRS configuration information for at least one TRP of the plurality of TRPs;
- and
- send a positioning measurement report, wherein the positioning measurement report comprises a set of PRS measurements performed on a first subset of TRPs of the plurality of TRPs and a set of estimated measurements determined for a second subset of TRPs of the plurality of TRPs, wherein a total number of TRPs included in the first and second subsets of TRPs is at least the minimum number of TRPs for which PRS measurements are to be reported.

A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
- receiving configuration information, wherein the configuration indicates positioning reference signal (PRS) configuration information for each of a plurality of transmission/reception points (TRPs), wherein the configuration information indicates one or more criteria for requesting PRS measurement assistance information, and wherein the configuration information indicates a minimum number of TRPs for which one or more PRS measurements are to be reported;
- determining that at least one criteria of the one or more criteria for requesting the PRS measurement assistance information is satisfied based on one or more measurements performed on one or more of the plurality of TRPs;
- sending a request for the PRS measurement assistance information, wherein the request indicates a location of the WTRU that is determined based on the one or more measurements performed on one or more of the plurality of TRPs;
- receiving the PRS measurement assistance information, the PRS measurement assistance information comprising one or more artificial intelligence/machine learning (AI/ML) model parameters;
- estimating one or more measurements for at least one TRP based on the one or more AI/ML model parameters and at least one measurement performed using the PRS configuration information for at least one TRP of the plurality of TRPs;
- and
- sending a positioning measurement report, wherein the positioning measurement report comprises a set of PRS measurements performed on a first subset of TRPs of the plurality of TRPs and a set of estimated measurements determined for a second subset of TRPs of the plurality of TRPs, wherein a total number of TRPs included in the first and second subsets of TRPs is at least the minimum number of TRPs for which PRS measurements are to be reported.
