Abstract

Certain aspects of the present disclosure generally relate to downlink (DL) based and uplink (UL) based positioning reference signal (PRS) techniques that may help facilitate positioning procedures in systems deploying narrowband devices, such as narrowband Internet of Things (NB-IoT) devices. An exemplary method that may be performed by a node includes monitoring for positioning reference signals (PRS) transmitted from one or more base stations within a narrowband region of a wider system bandwidth, wherein tones of the PRS are repeated across at least one of multiple symbols within a same subframe, or multiple consecutive subframes, and estimating timing from the one or more base stations based on the PRS.
