[Abstract]:The super-dense network is an effective solution for the future 5G network data traffic 1000 times and the user experience rate 10 ~ 100 times increase through the small base station encryption deployment of lifting spatial reuse. However the interference caused by cell intensive deployment and the frequent handoff of high speed mobile users due to the small coverage of small base stations will reduce the network capacity and user experience. Therefore, in order to consider the "coverage" and "capacity" of the future 5G super-dense network at the same time, a 5G super-dense network architecture with the main technical characteristics of control load separation and cluster centralized control is proposed. In addition, the implementation scheme is given for the macro-micro and micro-micro super-dense network deployment scenarios. Furthermore, the possible problems and challenges in the 5G super-dense network architecture are discussed, which provides a reference for further research and development.
