Fifth generation (5G) wireless communication systems will accommodate a wide range of emerging services with diverse service quality requirements, including e-healthcare and internet of things, with initial deployment from year 2020. The 5G network infrastructure will integrate a variety of network resources and technologies to support high service demands. The heterogeneity in both services and networks poses significant challenges to achieve network operation scalability, adaptability, and flexibility. The long-term goal of this research program is to develop efficient communication network solutions for effective end-to-end delivery of broadband multimedia services to mobile/stationary users and machines. The short-term objective in the next five years is to develop mathematical models to characterize relations among network control variables and service quality metrics, and to develop innovative service-customized networking algorithms and protocols for the wireless domain, under the emerging software defined networking (SDN) and network function virtualization (NFV) frameworks. This research program includes three thrust areas:1) Abstraction of wireless networks - The 5G systems will include cellular networks with macro-cells for large coverage and small-cells for high frequency reuse, and ad hoc networks for device/machine communications. Multiple network operation modes will coexist, with both centralized and distributed network control. We will study how to equivalently represent the complex wireless transmission systems by simple abstraction models to facilitate network management in the network layer of protocol stack;2) Energy efficient wireless communication networking With pervasive mobile communication services, the energy consumption in telecom systems has led to serious environmental and financial concerns. Energy efficient wireless networking solutions are required in order for 5G systems to be sustainable. We will investigate and develop energy and spectral efficient solutions to accommodate the anticipated huge growth in data traffic, exploring cooperative networking among heterogeneous networks;3) Efficient channel access over full-duplex (FD) transmissions: The emerging FD technique allows a radio terminal to transmit and receive simultaneously on the same channel, potentially doubling the radio spectrum efficiency. FD transmission complicates inter-link interference which can diminish the potential throughput gain. We will develop a channel access protocol to minimize new interference from FD transmissions, and to maximize statistical multiplexing of radio resources to accommodate data traffic dynamics in both time and space domains.This cutting-edge research will generate new ideas and techniques for developing 5G networks, which will help to foster a vital competitive edge for the Canadian telecom industry.

第五代（5G）无线通信系统将适应各种具有不同服务质量要求的新兴服务，包括电子医疗保健和物联网，从2020年开始初步部署。5G网络基础设施将整合各种网络资源和技术，以支持高服务需求。服务和网络的异构性对实现网络操作的可扩展性、适应性和灵活性提出了重大挑战。该研究计划的长期目标是开发高效的通信网络解决方案，为移动的/固定用户和机器提供宽带多媒体服务。未来五年的短期目标是开发数学模型来表征网络控制变量和服务质量指标之间的关系，并在新兴的软件定义网络（SDN）和网络功能虚拟化（NFV）框架下为无线领域开发创新的服务定制网络算法和协议。该研究计划包括三个重点领域：1）无线网络的抽象-5G系统将包括具有用于大覆盖范围的宏小区和用于高频率重用的小小区的蜂窝网络，以及用于设备/机器通信的ad hoc网络。多种网络操作模式将共存，集中式和分布式网络控制都有。我们将研究如何等效地表示复杂的无线传输系统，通过简单的抽象模型，以方便网络管理的协议栈的网络层;2）能源效率的无线通信网络与普及的移动的通信服务，在电信系统中的能源消耗已导致严重的环境和财务问题。为了使5G系统可持续发展，需要节能的无线网络解决方案。我们将研究和开发能源和频谱效率的解决方案，以适应数据流量的预期巨大增长，探索异构网络之间的合作网络;3）全双工（FD）传输的有效信道接入：新兴的FD技术允许无线电终端在同一信道上同时发送和接收，可能使无线电频谱效率提高一倍。FD传输使链路间干扰复杂化，这会降低潜在的吞吐量增益。我们将开发一种信道接入协议，以最大限度地减少FD传输带来的新干扰，并最大限度地增加无线电资源的统计复用，以适应时间和空间域的数据流量动态。这项前沿研究将为开发5G网络提供新的想法和技术，这将有助于为加拿大电信行业培养至关重要的竞争优势。
