TECHNIQUES FOR LOCATING DEVICES USING NARROWBAND POSITIONING REFERENCE SIGNALS
First Claim
1. A method for wireless communications, by a base station (BS), comprising:
- determining resources within a narrowband region of a wider system bandwidth for transmitting a positioning reference signal (PRS);
transmitting the PRS using the determined resources; and
estimating a position of a wireless node based on at least one first measurement of a first reference signal and the PRS.

Abstract
Certain aspects of the present disclosure generally relate to DL-based and UL-based positioning reference signal (PRS) techniques that may help facilitate positioning procedures in systems deploying narrowband devices, such as NB-IoT devices. An exemplary method includes determining resources within a narrowband region of a wider system bandwidth for transmitting a positioning reference signal (PRS), transmitting the PRS using the determined resources, and estimating a position of a wireless node based on at least one first measurement of a first reference signal and the PRS transmitted within a narrowband region.
