报告题目：5G-6G: Vision, Requirements, Technical Challenges, Standardization &Implementations
5G is the next step in the evolution of mobile communication and will be a key component of the Networked Society. In particular, 5G will accelerate the development of the Internet of Things. To enable connectivity for a wide range of applications and use cases, the capabilities of 5G wireless access must extend far beyond those of previous generations of mobile communications. Examples of these capabilities include very high data rates, very low latency, ultra-high reliability, energy efficiency and extreme device densities, and will be realized by the development of LTE in combination with new radio-access technologies. Therefore, this talk explains the different key technology components of 5G from physical layer to core technologies and from implementation to standardization.
报告题目：Ultra Reliable and Low latency Communication (URLCC) for 5G, IoT, Time Sensitive Networking and V2X Communication
新一代移动服务与应用程序要求前所未有的超低时延、高可靠性、极大连接密度以及大幅度地改善能量功率，而5G移动通信的各种优越特性是可以满足这些要求的，并且能对其所带来的市场机遇充分利用。超可靠低延迟通信（URLLC）是一个典型的例子，它能支持一些关键性业务应用功能，如工业互联网，智能电网，远程医疗手术和智能交通系统。对于4G LTE，3GPP Release 14版本下的延迟目前在4毫秒范围内。URLLC是版本15的一部分，目标是延迟范围达到1毫秒以内。URLLC也非常适合需要端到端安全和99.999％可靠性的应用程序，并且在数据包传送的时间限制方面几乎是确定性的。物理层无疑是最具挑战性的，因为URLLC必须满足两个相互矛盾的要求：低延迟和超高可靠性。与传统的移动宽带应用相比，这是一种新类型的服务质量（QoS）。结合物理层，URLLC应用程序还需要低延迟回程和前传。虽然以太网被称为适用于数据和电信网络的广泛可用的低成本技术，但是为了满足超低时延与时间敏感型网络（TSN）特征，一系列为了降低网络时延的技术将会被应用。因此，我们将阐述关于5G的不同URLLC解决方案以及时间敏感型网络在loT和V2x通信的应用。
New services and applications requiring lower latency, better reliability, massive connection density, and improved energy efficiency are emerging in an unprecedented fashion. A variety of advanced features make 5G uniquely well positioned to meet all of these requirements and capitalize on these market opportunities. A prime example is Ultra-Reliable Low-Latency Communication (URLLC), a set of features designed to support mission-critical applications such as the industrial internet, smart grids, remote surgery, and intelligent transportation systems. With 4G LTE, latency is currently in the 4-millisecond range under 3GPP Release 14. URLLC is part of Release 15 and has a target of 1-millisecond. URLLC also is ideal for applications that require end-to-end security and 99.999 percent reliability, and it’s almost deterministic in time bounds on packet delivery. The physical layer is unquestionably the most challenging because URLLC must satisfy two conflicting requirements: low latency and ultra-high reliability. This combination is a vastly different type of quality of service (QoS) compared to traditional mobile broadband applications. Alongside with Physical layer, URLLC application also requires low latency backhaul and fronthaul. Ethernet is known as a widely available low-cost technology suitable for data and telecom networks. However, for meeting the extreme latency requirements, Time-Sensitive Network (TSN) features, composed of techniques for lowering the latency in networks, may be considered. Therefore, in this presentation, we will explain the different URLLC solutions for 5G and Time Sensitive networking with its applications to IoT and V2x communication.
