Wireless Resource Reuse Employing Fog Nodes with Interference Cancellation for D2D Communications

Abstract (in Japanese) (See Japanese page) 
(in English) In the next generation mobile communication system, the M2M (machine-to-machine) communication is required to meet high reliability, short delay time, and high power efficiency, as well as a large number of wireless terminals to be accommodated. The D2D (device-to-device) communication directly connects devices to other devices, which can satisfy most of the above requirements. Since M2M terminals have insufficient processing power and storage, a cloud on the base station has proposed to help the terminals do information processing. However, communications between the terminals and base station can drastically increase latency of M2M applications. To tackle this problem, the deployment of Fog Nodes, which locally manage the M2M communications near the terminals while processing data, has been proposed. Since the Fog Node increases the number of times of transmission more than the direct communication, however, the frequency resource is more likely to be exhausted. Therefore, it is necessary to improve frequency utilization efficiency by actively sharing the resource. For this purpose, the report proposes a transmission scheme to employ successive interference cancellation (SIC), one of the interference cancelers at the Fog Node and to share wireless channels with the cellular system. Computer simulations show that the proposed scheme can significantly improve the power efficiency, which is defined as the ratio of the channel capacity to the transmission power, although the delay time is longer than one slot time due to the increase in the number of times of transmission.
