Review of wireless big data in 5G: From physical layer to application layer

The 5
^th
generation wireless communication system has become popular in recent industry and academic studies. The 5G wireless communication system has advantages in spectrum efficiency, energy efficiency, transmission speed, latency, etc. However, current key techniques could not satisfy the gradually increased service on-demand requirements. In this work, we summarize the utilization of physical layer, link layer, network layer and application layer (upper layer) using big data related technology, and propose the advantages and further possible advances in such areas. Big data technology will help the network to perform operations more precise and effectively, from historical data, environmental data, transmission and user behaviors, etc. Suggestions that how to make big data and 5G system together are concluded.
