Analysis on technology schemes of applications in the 5G NR
SHEN Xia;LIU Hui;
A unified 5 G new radio(NR) will be designed to fulfill the technical requirements for the three kinds of classical 5 G applications, i.e., enhance mobile broadband(e MBB), ultra reliable low latency communications(URLLC), and massive machine type of communication(m MTC). The first edition of 5 G standard supporting e MBB and URLLC applications will be finished due to July, 2018. In the process of 5 G NR standardization, the involved key technologies are gradually settled. This paper will analyze the key technologies including frame structure, multiple-antenna transmission schemes, channel coding,waveform, non-orthogonal multiple access, and Hybrid Automatic Repeat request(HARQ) according to the latest 5 G NR development. The corresponding technology schemes to meet the requirements of e MBB, URLLC and m MTC are summarized afterwards.
