Techniques for locating devices using narrowband positioning reference signals

An apparatus for wireless communications, comprising:

• means for determining resources within a narrowband region of a wider system bandwidth for transmitting a positioning reference signal (PRS);
• means for transmitting the PRS using the determined resources;
• and
• means for estimating a position of a wireless node based on at least one first measurement of a first reference signal and the PRS.

An apparatus for wireless communications, comprising:

• a processing system configured to:
• determine resources within a narrowband region of a wider system bandwidth for transmitting a positioning reference signal (PRS),
• cause transmission of the PRS using the determined resources,
• estimate a position of a wireless node based on at least one first measurement of a first reference signal and the PRS;
• and
• a memory coupled with the processing system.

A computer readable medium for wireless communications storing computer executable code, the code comprising instructions for:

• 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.
