An Overview of 3GPP Positioning Standards

Abstract

With the growing demand for locating services in a variety of commercial applications, positioning techniques have been considered as a vital part in cellular networks. With the evolution from 2G to 5G, the positioning techniques have been enhanced in various aspects. In this paper, we summarize the evolution of positioning standards in the Third Generation Partnership Project (3GPP) and briefly introduce the new positioning standards in 5G NR (New Radio), which include new positioning requirements, the general positioning structure, new positioning reference signals, and general positioning methods.
