Non-Orthogonal Radio Access with Security Provisioning for Future Wireless Networks Recent years have witnessed a significant increase in the demand for pervasive deployment of wireless communications, including an increasingly widespread Internet-of-Things (IoT). While the race for increased data rates to provide multimedia streaming has continued through the enhanced mobile broadband (eMBB) pillar of wireless networks, supporting IoT has brought unexplored challenges. IoT includes both massive machine-type communications (mMTC), characterized by very high density of low-cost energy-efficient devices typically transmitting non-delay-sensitive data, and mission-critical low-latency ultra-reliable communications (URLLC). Correspondingly, potentially trillions of connected devices with heterogeneous quality-of-service requirements will be connected to future wireless networks, which will need to undergo substantial transformations at all levels of the network architecture. This proposal focuses on addressing challenges at the radio access level. Large-scale non-orthogonal radio access networks (NORANs) with cell densification and multiple co-occurring technologies, including full duplex and massive multiple-input multiple-output, will be examined in terms of interference characterization and management to satisfy the requirements of eMBB and emerging coexisting eMBB-URLLC scenarios. In addition, for mMTC, an aim is to design new non-orthogonal transmission schemes to allow massive connectivity of devices in uplink, along with receivers capable of detecting the activity and data of these devices. Ensuring security is crucial for the mMTC uplink transmission and large-scale NORANs. Devising transmission schemes which provide better security at the physical layer is another goal of this proposal. The proposed research program will develop new theoretical and practical frameworks for tackling crucial design challenges in future radio access networks, with security provisioning. By exploiting concepts from signal processing, information theory, optimization theory, and machine learning to solve challenges of future wireless networks, the highly qualified personnel trained under this program will acquire valuable skills to contribute to both the Canadian high-tech sector and research community. Furthermore, the research findings are anticipated to lead to new practical solutions for the benefit of the global telecommunications industry.

近年来，对无线通信的普及部署的需求显著增加，包括日益广泛的物联网（IoT）。虽然通过无线网络的增强型移动的宽带（eMBB）支柱，提高数据速率以提供多媒体流媒体的竞争仍在继续，但支持物联网带来了尚未探索的挑战。物联网包括大规模机器类型通信（mMTC）和关键任务低延迟超可靠通信（URLLC），其中mMTC的特点是非常高密度的低成本节能设备，通常传输非延迟敏感数据。相应地，可能有数万亿具有异构服务质量要求的连接设备将连接到未来的无线网络，这将需要在网络架构的各个层面进行实质性的转变。 该提案侧重于解决无线电接入层面的挑战。大规模非正交无线电接入网络（NORAN）与小区密集和多种共存的技术，包括全双工和大规模多输入多输出，将在干扰特性和管理方面进行检查，以满足eMBB和新兴的共存eMBB-URLLC场景的要求。此外，对于mMTC，目的是设计新的非正交传输方案，以允许上行链路中的设备的大规模连接，沿着能够检测这些设备的活动和数据的接收器。确保安全性对于mMTC上行传输和大规模NORAN至关重要。设计在物理层提供更好的安全性的传输方案是本提案的另一个目标。拟议的研究计划将开发新的理论和实践框架，以解决未来无线接入网络的关键设计挑战，并提供安全保障。通过利用信号处理，信息理论，优化理论和机器学习的概念来解决未来无线网络的挑战，在该计划下培训的高素质人员将获得宝贵的技能，为加拿大高科技部门和研究界做出贡献。此外，预计研究结果将为全球电信业带来新的实际解决方案。
