Toward Energy-Efficient and Ultra-Low Latency Wireless Networks: 5G and Beyond******The research program of the applicant is in the areas of wireless communications and networking.******In recent years, wireless service providers have deployed Long Term Evolution (LTE) systems to facilitate mobile users in using their smartphones or tablets to connect to the Internet, access social networks, and launch different types of real-time and streaming multimedia applications. With the proliferation of Internet of Things (IoT) devices and applications, the next generation of wireless networks, namely the fifth generation (5G) networks, aim to not only provide a higher data rate to the existing mobile users, but also to support the connection of potential billions of IoT devices to the Internet.******Machine-type communications (MTC) is an important enabler of IoT. The International Telecommunications Union classifies MTC into two categories: massive MTC (mMTC) and ultra-reliable and low latency communications (URLLC). mMTC is characterized by high connection density; i.e., a massive number of active low-cost and low-power MTC devices co-exist per cell. Sensor networks and wearables are examples of mMTC. URLLC requires reliable data transmissions with strict latency constraint of 10 milliseconds or less. URLLC is required for applications such as e-health and autonomous driving. To meet these challenging requirements, a true revolution of technologies in the radio access network and core network is needed. ******In this research program, the long-term objective is to support IoT applications with diverse delay and throughput requirements, and to improve the spectral and energy efficiencies of the emerging 5G wireless networks in a scalable manner. Within the five-year time frame, we will focus on the following inter-related short-term objectives: (a) to develop radio access network and core network architecture, incorporating software-defined networking (SDN), mobile edge computing, and dynamic network slicing, to improve the spectral efficiency and flexibility of 5G networks to support different types of devices (e.g., smartphones, MTC devices) and IoT applications; (b) to develop energy-efficient medium access control algorithms for mMTC devices, based on non-orthogonal multiple access (NOMA), to improve the scalability and connection density within a coverage area; and (c) to develop application-aware scheduling algorithms for URLCC devices, based on SDN, carrier aggregation, and NOMA, to support IoT applications with high reliability and ultra-low delay requirements.******We anticipate that our research will find practical novel solutions and applications for the benefit of the local and the global telecommunications industry for 5G systems and beyond. They are expected to have a lasting impact in contributing towards the long-term competitiveness of Canada's technological innovation.

迈向节能和超低延迟无线网络：5G及以后 * 申请人的研究计划是在无线通信和网络领域。近年来，无线服务提供商已经部署了长期演进（LTE）系统，以便于移动的用户使用他们的智能手机或平板电脑连接到互联网、访问社交网络以及启动不同类型的实时和流媒体应用。随着物联网（IoT）设备和应用的激增，下一代无线网络，即第五代（5G）网络，不仅旨在为现有的移动的用户提供更高的数据速率，而且还旨在支持潜在的数十亿物联网设备连接到互联网。机器类型通信（MTC）是物联网的重要推动力。国际电信联盟将MTC分为两类：大规模MTC（mMTC）和超可靠低延迟通信（URLLC）。mMTC的特征在于高连接密度;即，每个小区共存大量的活动的低成本和低功率MTC设备。传感器网络和可穿戴设备是mMTC的示例。URLLC要求可靠的数据传输，具有10毫秒或更短的严格延迟限制。URLLC适用于电子健康和自动驾驶等应用。为了满足这些具有挑战性的要求，需要在无线电接入网络和核心网络中进行真正的技术革命。** 在这项研究计划中，长期目标是支持具有不同延迟和吞吐量要求的物联网应用，并以可扩展的方式提高新兴5G无线网络的频谱和能源效率。 在五年时间内，我们会专注于以下相互关联的短期目标：（a）开发无线接入网络和核心网络架构，结合软件定义网络（SDN）、移动的边缘计算和动态网络切片，以提高5G网络的频谱效率和灵活性，以支持不同类型的设备（例如，（B）基于非正交多址（NOMA）开发用于mMTC设备的节能介质访问控制算法，以提高覆盖区域内的可扩展性和连接密度;以及（c）基于SDN、载波聚合和NOMA，开发用于URLCC设备的应用感知调度算法，支持具有高可靠性和超低延迟要求的物联网应用。**我们预计，我们的研究将找到实用的新解决方案和应用，为本地和全球电信行业的5G系统及以后的利益。预计它们将对加拿大技术创新的长期竞争力产生持久的影响。
