Abstract
In future wireless systems, implementation of massive multiple-input multiple-output (MIMO) and heterogeneous networks (HetNets) technologies will lead to higher capacity of networks, but also result in energy problems and resistance for operators to provide desirable services. In this paper, we focus on energy-saving problem, and try to improve the energy efficient (EE) with required quality of service (QoS) maintained. We will first indicate the problem of energy use in modern wireless communication systems, then address a massive MIMO-based HetNets framework with software defined network (SDN) as the central controller of radio resource management (RRM). After that, we will develop a scheme that reduces the energy use of the system, which is monitored and managed by SDN controller at the controlling pannel. Finally, we will deploy the scheme to achieve a higher EE with sufficient QoS.
