Mobile communication has profoundly changed peoples life, but peoples pursuit for higher performance of mobile communication has never stopped. In order to cope with the future of mobile data traffic explosive growth, the connection of massive device, the continuous emergence of various new services and applications scene, the fifth generation mobile communication (5G) system will emerge as times require.The necessity of 5G Why does the vision of 5G emerge？5G will make information break through the limitation of time and space, providing excellent interactive experience and imme-rsive information feast for the user.Through the seamless fusion way, 5G will close the distance of all things, realize the intelligent interconnection between man and all things on earth.5G will penetrate into all areas of the society in the future, constructs an all-wave customer-focus?information ecology system.5G will provide the access rate of fiber like, the using experience of “zero delay”, the ability to connect billions of devices, super high flux density, super high connection number density , super high mobility and other multi scene favorable service and intelligent optimization of business and user perception.At the same time, 5G will bring the network over a hundred times the energy efficiency and ultra hundred times the bit cost reduction. Finally 5G will realize the general hope of “Get the information whenever you want and all things on earth are at your fingertips”.4Research status and cha
