This paper introduces a Software Defined Network (SDN) architecture for 5G dense multi-infrastructure provider deployed wireless backhaul networks. The architecture contains a two-tier controller in a hierarchical setup aiming to offload some of the control functionalities from the central controller to a collection of logically distributed dynamically configured local controllers in order to balance...
The anticipated 1000 fold traffic growth in 2020 and the explosion of new services and applications including the massive Internet of Things, tactile internet, etc. pose tough challenges for the next generation mobile network. A soft end-toend solution from the core network to the radio access network, as well as the air interface is envisioned as the key to meet the extremely stringent demands. This...
Efficient discovery of multiple small cells is important to features such as small cell on/off, load balancing, CoMP (Coordinated Multi-point Transmission), e-ICIC (enhanced-Inter-Cell Interference Coordination) in LTE (Long Term Evolution) hyper-dense networks. However, severe interference in the Hyper-Dense Networks imposes great difficulty on efficient discovery of small cells. This paper proposes...
In this paper, we study and optimize the energy efficiency performance of heterogeneous network (HetNet) with the help of self-organized network (SON). Firstly, we propose a new and general power model for different types of base stations (BSs), where the impact of system load (including power load and bandwidth load), antenna port, carrier number, as well as the power supply and cooling system, is...
