Ultra-dense small cell deployment is seen as a necessary means to address the explosive mobile traffic growth in the near future. However, a large-scale small cell deployment can substantially increase the network energy consumption with strong ecological and economic implications. In this article, we introduce an energy-efficient macro assisted sleep mode scheme in heterogeneous networks to reduce cellular networks’ power consumption. The designed scheme takes into account that (i) macro base station’s power consumption is varying with the load, (ii) macro starts a UE-small cell connection procedure as soon as a connected UE is required to start receiving data is potentially suboptimal in terms of energy consumption. Furthermore, we present the procedures of the proposed macro assisted sleep mode scheme. By our calculation and analysis, our scheme can yield a further 5% energy savings with respect to the amount of energy savings obtained with existing schemes.
