Uplink Pilot Power Allocation for MA-MIMO-HetNet Remote Health Systems

In this paper, we study the uplink pilot transmit power allocation of information communication technology (ICT)-assisted remote health system with massive multi-input multi-output (MA-MIMO) and heterogeneous cellular network (HetNet), which is so crucial to effectively mitigate the interference for improving the system performance that more patients can get high-quality service in remote areas simultaneously. We propose a pilot transmit power allocation method which is inspired by Water-Filling (WF) algorithm to increase the system capacity and obtain the effect of pilot transmit power in MA-MIMO-HetNet remote health system. Simulation results demonstrate that the system uplink capacity can be improved significantly by the proposed scheme and illustrate the influence of different total pilot transmit power on system performance, while imposing a scarcely increased complexity.
