Abstract

Abstract

En 中文
Along with the surge of data traffic amount, Long Term Evolution (LTE)-based Device-to-Device (D2D) communication is emerging as a key data traffic offloading technology. However, current LTE-based D2D communication has limitations such as the lack of feedback mechanism, causing difficulty for efficient radio resource use. In this paper, we propose a feedback mechanism to increase the spectral efficiency of LTE-based D2D communication. In particular, the proposed feedback mechanism is designed to minimize signaling overhead and D2D Rxs can use the proposed feedback mechanism without any connection to Base Station (BS). On top of the proposed mechanism, we also propose feedback-aided rate adaptation and recovery schemes. Through extensive simulations, we verify that the proposed solutions achieve solid performances, e.g., goodput and latency, under various channel environments. (C) 2018 Elsevier B.V.
