通信工程文献翻译——摘要
在此篇文章中,一个基于D2D通信的3GPP(第三代合作伙伴项目)LTE-Advanced蜂窝网络是作为本地服务的推动因素来研究的,并且受限于影响原蜂窝网络的干扰。研究方法是将一个D2D通信(模块)紧密集成到一个高级LTE网络。特别之处在于,我们为D2D通信会话的建立和管理提出的机制涉及到了LTE系统架构演进过程。此外,我们提出了基于在限制干扰的局部(或本地)区域的系统模拟的数值结果。我们的研究结果表明,D2D通信可以增加蜂窝小区中所观察到的总吞吐量。
介绍
近年来,科学家们已经对第三代合作伙伴计划(3GPP)长期演进(LTE)的发展进行了大量努力,他们提供通用移动电信系统(UMTS)陆地无线电接入(EUTRA)和EUTRA网络(EUTRAN)技术用于更高数据速率的演以及用于高效网络和成本节省操作的系统架构演进的系统容量(SAE)。

3GPP最近定义了一个对于进一步研究LTE-Advanced的项目,这将为LTE准备新的技术组件以满足IMT-Advanced(高级国际移动通信)要求,同样也要满足局域情况的要求。IMT-Advanced将提供高达100 MHz的高带宽,以实现更高的数据速率,全球运营机制和规模经济(因经营规模扩大而得到的经济节约)来支持范围广阔的服务。这种未来的无线电接入系统在各种频带上的载波带宽和载波频率方面是可扩展的[1]。本文介绍了迄今为止尚未充分考虑的LTE-Advanced的技术组件:将设备到设备(D2D)通信作为蜂窝网络的底层。
近年来,无线局域网(WLAN)变得越来越受欢迎,因为它们能够以低成本的基础设施来访问因特网和本地服务,并且能在免许可证频带中廉价和快速地访问频谱。然而,在具有许可证的频带上的操作是具有好处的,因为它可以保证访问是在计划(干扰)环境而不是......
ABSTRACT
In this article device-to-device (D2D) communication underlaying a 3GPP LTE-Advanced cellular network is studied as an enabler of local services with limited interference impact on the primary cellular network. The approach of the study is a tight integration of D2D communication into an LTE-Advanced network. In particular, we propose mechanisms for D2D communication session setup and management involving procedures in the LTE System Architecture Evolution. Moreover, we present numerical results based on system simulations in an interference limited local area scenario. Our results show that D2D communication can increase the total throughput observed in the cell area.
INTRODUCTION
Major effort has been put in recent years on the development of Third Generation Partnership Project (3GPP) Long Term Evolution (LTE),which provides Evolved Universal Mobile Telecommunications System (UMTS) terrestrial radio access (EUTRA) and EUTRA network (EUTRAN) technology for higher data rates and system capacity, and the System Architecture Evolution (SAE) for efficient networking and cost saving operation.
3GPP has recently defined a further study item for LTE-Advanced, which shall prepare new technology components for LTE to meet the IMT-Advanced requirements, also in the local area scenario. IMT-Advanced will offer high bandwidths up to 100 MHz for higher data rates, global operation, and economy of scale to support a wide range of services. Such future radio access systems will be scalable in terms of carrier bandwidth and carrier frequencies on......
