项目摘要

The fifth generation (5G) wireless networks aim to enable order-of-magnitude increases in connectivity, capacity, and speed. Such a goal can be achieved in part by utilizing larger frequency bandwidth or deploying denser base stations. However, as the number of wireless devices is increasing rapidly, it is inevitable that multiple devices communicate over the same time and spectrum. Consequently, mitigating the interference in concurrent transmissions is a pivotal challenge for the 5G networks. In this project, we build on two recent breakthroughs by the PI, Dr. Lele Wang, and her collaborators on low-complexity coding schemes that achieve the theoretically optimal performance of maximum likelihood decoding. We will investigate the feasibility of these schemes in various 5G user cases such as enhanced mobile broadband and mission-critical machine type communication that requires high reliability and low latency. The expected outcomes from the project are novel interference mitigation schemes that significantly improve upon the existing schemes in 4G networks. These algorithms will be incorporated as the physical layer interference management scheme in the real-world 5G hub Rogers Communication Inc. will build on the University of British Columbia campus. This project will be beneficial to ensure Canada remains as leaders in communication technology. It will also create invaluable training opportunities for involved students and postdoctoral researchers to gain research skills and expertise in wireless communication technology.

第五代（5G）无线网络旨在使连通性，容量和速度提高刻度级。可以通过更大的频率带宽或部署更密集的基站来部分实现此类目标。但是，随着无线设备的数量迅速增加，不可避免地会在同一时间和频谱中通信。因此，减轻对并发传输的干扰是5G网络的关键挑战。在这个项目中，我们建立在PI最近的两个突破，Lele Wang博士及其在低复杂性编码方案方面的合作者，这些方案实现了最大似然解码的理论上最佳性能。我们将调查这些方案在各种5G用户案例中的可行性，例如增强的移动宽带和关键任务机器类型通信，这些通信需要高可靠性和低潜伏期。该项目的预期结果是新型的干扰缓解方案，可显着改善4G网络中现有方案。这些算法将在现实世界中5G Hub Rogers Communication Inc.中作为物理层干扰管理计划合并，将在不列颠哥伦比亚大学校园内建立。该项目将有益于确保加拿大作为通信技术领导者的领导者。它还将为参与的学生和博士后研究人员创造宝贵的培训机会，以获得无线通信技术的研究技能和专业知识。
