Technical Field

Background
To meet the requirement of diversified applications of the Internet of Things, a new narrowband wireless access system NB-IoT (Narrow Band Internet of Things) is introduced in 3GPP (3rd Generation Partner Project) Rel-13. In addition to NB-IoT systems, 3GPP is also standardizing the characteristics of emtc (enhanced Machine Type communication). NB-IoT and eMTC are each oriented to different target market needs.
The NB-IoT system of Rel-13 and the eMTC system of Rel-13 are enhanced in 3GPP Rel-14. For NB-IoT, an important enhancement aspect is to give more functions to non-anchor physical resource blocks, such as supporting transmission of paging channel, supporting transmission of random access channel, etc., and introduce the functions of positioning and multicasting. In 3GPP Rel-15, NB-IoT is further enhanced, including reducing power consumption, enhancing measurement accuracy, introducing special scheduling requests and the like. In particular, support for TDD (Time Division Duplex) is also introduced in Rel-15.
