The dawn of the Internet of Everything (IoE), with the continuous growth of wireless capacity, requires revolutionary paradigm shifts from enhanced mobile broadband (eMBB) to ultra-reliable and low-latency communications (URLLC) services. Fifth generation (5G) new radio (5G NR) system was branded as a key IoE launcher. Nevertheless, this remains to be realized. In the meantime, new IoE services such as eXtended reality (XR), telemedicine, connected autonomous systems, etc., are in massive expansion. These applications not only require high data rates, reliability, and low latency both on uplink (UL) and downlink (DL), but also an end-to-end co-design of computing functionalities, communication, and control. To meet these stringent requirements, sixth generation (6G) and beyond (6GB) wireless networks come to play to answer the challenges arising with the new IoE applications. To meet the new requirements outlined above, new radio access technologies (RATs) must be integrated into 6GB networks that are expected to rely not only on conventional spectrum (i.e., sub-6 GHz and mmW), but also on new frequency bands unchartered yet, namely the THz band and visible light communications (VLC) which promise to meet the demands for a fully connected and intelligent digital world offering massive-scale communications. Besides the new spectrum, future 6GB RATs will include eventually a set of new technologies and network architectures that have been recently enabled by research advancements in the PHY layer but are not yet part of 5G such as intelligent reflecting surfaces (IRS) and cell-free ultra-massive multiple input multiple output (CF-UM-MIMO). The objective of this proposal is to produce innovative solutions at multiple fronts including transceiver designs, new relaying solutions, and network architecture to keep up with future 6GB stringent requirements. This includes new channel parameter estimation techniques and novel robust distributed collaborative beamforming (RDCB) designs for UM-MIMO THz transceivers. Besides, we plan to investigate new synchronization and channel estimation techniques and RDCB designs over IRS-aided communication links. On another front, we plan develop innovative CF-UM-MIMO architectures for future 6GB networks. Under the umbrella of this program and relying on its timely scope and on the applicant's record, major technological transfers are expected through potential patent applications, assistance in strategic product & business development choices, and standardization effort. Tremendous scientific, economic, and social benefits for Canada are expected from this program by: i) advancing know-how in crucial technical areas that enable 6GB networks & IoE apps, ii) facilitating the advent of the next wireless networks revolution in the 21st-century digital economy, iii) assisting technology transfers to Canadian industry, and iv) providing top-quality HQP training in a vibrant ICT sector.

随着无线容量的持续增长，所有事物的互联网（IOE）的曙光需要革命性的范式从增强的移动宽带（EMBB）转变为超可靠和低延迟通信（URLLC）服务。第五代（5G）新收音机（5G NR）系统被烙印为关键IOE发射器。然而，这还有待实现。同时，新的IOE服务，例如扩展现实（XR），远程医疗，连接的自主系统等，都处于大规模扩展。这些应用程序不仅需要上行链路（UL）和下行链路（DL）上的高数据速率，可靠性和较低的延迟，而且还需要计算功能，通信和控制的端到端共同设计。为了满足这些严格的要求，第六代（6G）和超越（6GB）无线网络开始播放，以应对新的IOE应用程序引起的挑战。要满足上面概述的新要求，必须将新的无线电访问技术（大鼠）集成到6GB网络中，预计不仅要依赖于常规频谱（即SUB-6 GHz和MMW），而且还依赖于尚未尚无新的频段，还依靠迄今尚未传授的新频段，即THZ带和可见的光线通信（VLC），以满足群众的要求，并完全符合智慧的智能，并有足够的智能智能，并有任何智慧的智能。除了新的光谱外，未来的6GB大鼠最终还将包括一组新技术和网络体系结构，这些技术和网络架构最近通过PHY层中的研究进步启用，但尚未属于5G的一部分，例如智能反射表面（IRS）和无单元的无单元超大型多数输入（CF-UM MIMO）。 该提案的目的是在多个方面生产创新的解决方案，包括收发器设计，新继电器解决方案和网络体系结构，以跟上未来的6GB严格要求。这包括新的通道参数估计技术和用于UM-MIMO THZ收发器的新型鲁棒分布式协作波束形成（RDCB）设计。此外，我们计划在IRS辅助通信链路上研究新的同步和渠道估计技术和RDCB设计。在另一个方面，我们计划为未来6GB网络开发创新的CF-UM-MIMO架构。 在该计划的保护下，依靠及时的范围和申请人的记录，可以通过潜在的专利申请，战略产品和业务开发选择方面的帮助以及标准化工作来期望进行重大的技术转移。 Tremendous scientific, economic, and social benefits for Canada are expected from this program by: i) advancing know-how in crucial technical areas that enable 6GB networks & IoE apps, ii) facilitating the advent of the next wireless networks revolution in the 21st-century digital economy, iii) assisting technology transfers to Canadian industry, and iv) providing top-quality HQP training in a vibrant ICT sector.
