Abstract

[HetSNets can increase the SE and throughput with the hierarchical deployment of low power nodes as well as the macro nodes. In order to meet the increasing capacity requirements of future 5G wireless networks, much more number of low power nodes needs to be deployed if no new frequency resources becomes available, which may cause the serious interference between nodes. Then, the introduction of mm-wave communications with massive MIMO provides unprecedented spectral resources for HetSNets in 5G. However, major challenges remain for implementing mm-wave massive MIMO in HetSNets. To this end, we introduce several typical deployment scenarios for HetSNets with mm-wave massive MIMO. A frame structure based on TDD is proposed and discussed then in details. Next, the challenges and possible solutions relating to both physical, MAC and network layers are studied. Finally, system-level simulations are implemented to evaluate the system performance of HetSNets with mm-wave massive MIMO.]
