Abstract

Abstract: Seamless wide-area coverage, high-capacity hot-spot, low-power massive-connections and low-latency high-reliability are the four major technical scenarios of the fifth generation of mobile communications system(5G). The location information of the mobile terminal is not only the demand of new services, but also effectively meets the key challenges faced by 5G new services in terms of traffic density, number of connections, ultra-low latency, high reliability, and high mobility. A survey of positioning technology oriented to 5G is given by analyzing the main directions involved in positioning. Firstly, starting from the demand of 5G technical scenarios, the research progress of existing positioning technology for 5G demand is introduced. After the classification of positioning method, the 5G technologies that are good for localization is summarized. Finally, the challenges of 5G mobile station positioning are analyzed, and the future research directions are given.

Key words: positioning technology, the fifth generation of mobile communications system, cooperative localization, non-cooperative localization
