Technologies to Support Enhanced Mobile Broadband and Tactile Internet Applications in 5G Wireless Systems

无线蜂窝网络(例如，长期演进(LTE)系统)的成功部署使使用智能手机或平板电脑的移动用户能够启动不同的应用，包括语音、互联网网页浏览、视频会议、视频流、社交网络和其他基于位置的服务。新兴的第五代(5G)无线系统及以后的系统旨在支持具有不同服务需求的其他新服务和应用。第三代合作伙伴项目和下一代移动网络联盟定义了许多用例。它们包括：(A)增强型移动宽带(EMBB)，支持超高清3D视频流、虚拟/增强现实等应用；以及(B)超可靠、低延迟通信(URLLC)，支持触觉互联网等应用，以及那些需要10毫秒或更短延迟且可靠性超过99.999%的物联网应用。在这个项目中，我们的长期目标是开发一个灵活、可扩展和健壮的异构无线移动网络架构框架，支持高效的网络切片、移动网络虚拟化、灵活的空中接口和多无线电接入技术。为了实现这一长期目标，我们确定了以下将立即产生影响的短期目标：(1)开发高效的网络切片技术和灵活的空中接口，以支持不同的应用，包括eMBB、URLLC和触觉互联网；(2)设计实用的基于毫米波的波束形成和调度算法，以可扩展的方式增加网络容量，并支持无缝切换，以促进用户的移动性；以及(3)开发无线编码缓存技术，以增加每个用户的吞吐量和改善延迟性能。预计结果将通过促进技术方法和标准政策，从而改善服务、降低成本和长期竞争力，从而使我们的行业合作伙伴受益。该项目将培养大批高素质人才，以服务于加拿大快速发展的5G无线系统领域的需求。

The successful deployment of wireless cellular networks (e.g., Long Term Evolution (LTE) systems) enables mobile users using smartphones or tablets to launch different applications including voice, Internet web browsing, video conferencing, video streaming, social networking, and other location-based services. The emerging fifth generation (5G) wireless systems and beyond aim to support other new services and applications with diverse service requirements. The Third Generation Partnership Project and the Next Generation Mobile Networks Alliance have defined a number of use cases. They include: (a) enhanced mobile broadband (eMBB), which supports applications such as ultra-high-definition 3D video streaming, virtual/augmented reality; and (b) ultra-reliable and low-latency communications (URLLC), which support applications such as tactile Internet and those Internet of Things (IoT) applications that require a latency of 10 milliseconds or less as well as a reliability of more than 99.999%. In this project, our long-term objective is focused on developing a flexible, scalable, and robust heterogeneous wireless mobile network architecture framework, which supports efficient network slicing, mobile network virtualization, flexible air interface, and multi-radio access technologies. To achieve this long-term objective, we have identified the following short-term objectives that will make an immediate impact: (1) develop efficient network slicing techniques and flexible air interfaces to support different applications, including eMBB, URLLC and tactile Internet; (2) design practical millimeter wave based beamforming and scheduling algorithms to increase network capacity in a scalable manner and to support seamless handover to facilitate users' mobility; and (3) develop wireless coded caching techniques to increase the per-user throughput and improve the delay performance. The outcomes are expected to benefit our industrial partners by promoting technical methods and standard policies that lead to service improvement, cost reduction, and long-term competitiveness. The project will prepare a large number of highly qualified personnel to serve the needs of the fast-evolving field of 5G wireless systems in Canada.
