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）无线网络旨在实现连接、容量和速度的数量级增长。这样的目标可以部分地通过利用更大的频率带宽或部署更密集的基站来实现。然而，随着无线设备的数量迅速增加，多个设备在相同的时间和频谱上进行通信是不可避免的。因此，减轻并发传输中的干扰是5G网络的关键挑战。在这个项目中，我们建立在PI，Lele Wang博士和她的合作者在低复杂度编码方案上的两个最新突破的基础上，这些编码方案实现了最大似然解码的理论最佳性能。我们将研究这些方案在各种5G用户案例中的可行性，例如需要高可靠性和低延迟的增强型移动的宽带和关键任务机器类型通信。该项目的预期成果是新的干扰缓解方案，大大改善了4G网络中的现有方案。这些算法将作为物理层干扰管理方案纳入现实世界的5G中心罗杰斯通信公司。将建在不列颠哥伦比亚省的校园里。该项目将有利于确保加拿大继续成为通信技术的领导者。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。
