A Technology Vision of the Fifth Generation (5G) Wireless Mobile Networks

摘要

5G is now the next generation of wireless communication systems. The general demonstration of one technology vision for fifth generation mobile networks is presented in this work. The vision of 5G technology provides guidance for the definition of requirements, architecture, and other aspects. By expanding the performances limits of mobile networks, it is necessary for the 5G to include a flexible designing which can optimize network utilization with large range of examples for partnership and business models. The 5G should include flexibility to optimize the network usage by design. Modular network functions with the ability of on demand deployment and scaling capabilities need to be included in the architecture. The purpose of this inclusion would be to handle the accommodation of various demands in a cost-effective and agile manner. Direct communication in D2D services is one of the new 5G networks characteristics. Advanced technologies such as massive MIMO and millimeter-wave radio systems have significant impact on design of cellular architecture. It is crucial for 5G technology to maintain a massive traffic volume owing to increase efficiency of radio link and density of cells. Also, it is necessary for the network to be transformed in a cloud architecture, which coordinates radio resources of multi-radio access, and inter-cell interference during network deployment. Research trends in 5G tell us that using an aggregation of technologies, it is possible to realize numerous goals. Our use case study for the perspective period post-2020 shows extremely broad variety of applications and their attributes performance.
