可见光和射频频带的组合用于设备到设备通信
Combination of Visible Light and Radio Frequency Bands for Device-to-Device Communication
摘要:
未来的移动网络应该服务于用户所需的高数据率。为了适应高数据率,可以利用附近移动终端(MT)之间的直接通信,称为设备到设备(D2 D)通信。此外,高频带中的通信(例如可见光通信(VLC))也被预见为高数据率的使能器。在传统的D2 D通信中,成对的MT应该重用相同的频率以保持系统的高频谱效率。然而,这意味着D2 D对之间的干扰或复杂且高级的资源分配算法的利用。在本文中,我们提出了一个新的概念D2 D通信相结合的VLC和RF技术,以最大限度地提高系统的容量。本文提供了所提出的概念的操作限制的分析,并研究了由RF和VLC频带的组合使用引入的容量增益用于D2 D。此外,我们还讨论了与所提出的RF-VLC D2 D概念相关的几个实际问题。进行的分析表明,与独立RF D2 D和VLC D2 D相比,RF-VLC D2 D能够分别将室内场景中的容量提高4.1和1.5倍。
英文摘要:
Future mobile networks are supposed to serve high data rates required by users. To accommodate the high data rates, a direct communication between nearby mobile terminals (MTs), known as Device-to-device (D2D) communication, can be exploited. Furthermore, a communication in high frequency bands, such as, visible light communication (VLC), is also foreseen as an enabler for the high data rates. In conventional D2D communication, pairs of the MTs should reuse the same frequencies to keep a high spectral efficiency of the system. However, this implies either interference among the D2D pairs or utilization of complex and advanced resource allocation algorithms. In this paper, we propose a new concept for D2D communication combining VLC and RF technologies in order to maximize capacity of the system. This paper provides an analysis of the operational limits for the proposed concept and investigates capacity gains introduced by the combined usage of RF and VLC bands for D2D. Moreover, we discuss several practical issues related to the proposed RF-VLC D2D concept. Performed analyses show that the RF--VLC D2D is able to improve the capacity in an indoor scenario by a factor of 4.1 and 1.5 when compared to stand-alone RF D2D and VLC D2D, respectively.
