On design of Interference Self-Coordination (ISC) solution to enable mHealth services in HetNets

As defined by WHO and ITU, mobile health (mHealth) is expected to change healthcare service modes and will be at the core of the future healthcare system. As for considering human activities, hotspot and indoor environments are the major scenarios to carry mHealth services (e.g., homecare). To accommodate mHealth services, dense/superdense small-cell layout in Heterogeneous Networks (HetNets) is a typical deployment scenario. On the other hand, mHealth services should be guaranteed with reliability and security in any wireless networks, since health-risk or medical-related information involved. In this study, we focus on how to guarantee control-information delivery in HetNets, so that mHealth users can be allowed to access wireless facilities reliably. To handle this challenge, we extend Interference Self-Coordination theory into HetNets, in order to enable service-sensitive healthcare services in mobile networks if needed. The system-level simulation experiments demonstrate that our proposal can achieve significant performance gain: the SINR of control channel is increased by around +104%; the packet error-loss rate can be reduced by -73%; the packet delay is reduced by -46%. These gains are valuable for quality-sensitive applications in HetNets, such as mHealth.
