Abstract

Systems and methods for configuring and generating Narrowband Positioning Reference Signals (NPRS) for NB-IoT are provided. A network node provides (NPRS) configuration information indicating a systemframe number (SFN) dependent resource mapping. A wireless device obtains a NPRS in accordance with the indicated SFN dependent resource mapping and uses it to perform a radio measurement operation.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 654,013, filed April 6, 2018, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates generally to wireless communications and wireless communications networks. Background technique [0004] The Internet of Things (IoT) is a vision of a future world in which all things that can benefit from connectivity will be connected. Cellular technologies are being developed or evolved to play a role in the IoT world, especially Machine Type Communications (MTC). MTC is characterized by lower data rate requirements than, for example, mobile broadband, but higher requirements for low-cost device design, greater coverage, and the ability to operate on batteries for years without recharging or replacing them. high. To meet IoT design goals, standardization entities such as the 3rd Generation...
