Research on Duplex Mode of Railway Next Generation Wireless Communication
Wang Wei, Jianlin Guo · 2016
This paper analyze the difference of LTE FDD and LTE TDD, including specification evolution, protocol stack, frame structure, synchronous signal, HARQ, beamforming, frequency band and so on. Mainly focuses on the network performance analysis of LTE-R in FDD and TDD, including coverage, capacity, network redundancy, service characteristic and high speed adaptability. Industry chain is also be compared, in the end the duplex mode selection advice of railway next generation wireless communication is proposed.
