The vision of the next generation of 5G wireless communications is to provide very high data rates (typically Gbps order), extremely low latency, multiple increase in base station capacity, and significant improvements in QoS ) 4G LTE networks. The growing proliferation of smart devices, the introduction of new emerging multimedia applications along with an exponential increase in the demand and use of wireless data (multimedia) is already creating a significant burden for existing cellular networks. 5G wireless systems, with improved data rates, capacity, latency, and QoS, are expected to be the panacea for most current cell network problems. In this survey, we do a comprehensive review of the wireless evolution to 5G networks. First we discuss the new architectural changes associated with the design of the radio access network (RAN), including air interfaces, intelligent antennas, clouds and heterogeneous RAN. Subsequently, we carried out an in-depth study of the new technologies of physical layer of wave mm, which includes the new estimation of channel model, directional antenna design, beamforming algorithms and massive MIMO technologies. Next, we discuss the details of the MAC layer protocols and multiplexing schemes needed to effectively support this new physical layer. We also look at killer applications, considered as the main driving force behind 5G. In order to understand the improved user experience, we offer highlights of the new QoS, QoE and SON functions associated with 5G evolution. To alleviate the increase in network energy consumption and operating expenses, we make a detailed review of energy awareness and cost efficiency. As understanding the current status of 5G implementation is important for eventual commercialization, we also discuss relevant field trials, management tests and simulation experiments. Finally, we point out the main research problems that exist and identify possible future research directions.
