用于增强蜂窝网络性能的D2D通信的操作区域

Operational Region of D2D Communications for Enhancing Cellular Network Performance

Stelios Stefanatos, Antonis G. Gotsis, Angeliki Alexiou

摘要:

向蜂窝网络成功部署任何新元件/特征的重要使能器是对其引入将增强性能的操作条件的调查和表征。尽管已经存在关于设备到设备(D2 D)通信的潜力的重要研究活动,但是目前没有明确的指示D2 D通信是否实际上能够为广泛的操作条件提供益处,从而证明将其引入系统是合理的。本文试图填补这一空白,采取随机几何的方法来表征一组(区域)的操作条件,D2 D通信提高性能的平均用户速率。对于重负载网络的实际感兴趣的情况,以封闭形式提供操作区域作为各种参数(诸如最大D2 D链路距离和用户密度)的函数,反映宽范围的操作条件(点)。它示出,在适当的部署方案下,D2 D通信确实可以是有益的,不仅对于通常考虑的制度的“邻近通信”,但到广泛的操作条件,包括D2 D链路距离相当的距离到蜂窝接入点和相当大的用户密度。

英文摘要:

An important enabler towards the successful deployment of any new element/feature to the cellular network is the investigation and characterization of the operational conditions where its introduction will enhance performance. Even though there has been significant research activity on the potential of device-to-device (D2D) communications, there are currently no clear indications of whether D2D communications are actually able to provide benefits for a wide range of operational conditions, thus justifying their introduction to the system. This paper attempts to fill this gap by taking a stochastic geometry approach on characterizing the set (region) of operational conditions for which D2D communications enhance performance in terms of average user rate. For the practically interesting case of a heavy loaded network, the operational region is provided in closed form as a function of a variety of parameters such as maximum D2D link distances and user densities, reflecting a wide range of operational conditions (points). It is shown that under the appropriate deployment scheme, D2D communications can indeed be beneficial not only for the usually considered regime of "proximal communications" but to a wide range of operational conditions that include D2D link distances comparable to the distance to the cellular access point and considerably large user densities.
