Wireless services play an increasingly important role in our society transforming people's lives, industry processes, and society interactions. Although they help to reduce CO2 emissions, for example with telecommuting and increase in production efficiency, they also cause an increase in service demand and economic growth, leading to an overall increase in CO2 emissions. With an objective to reach net-zero emissions in several countries, including Canada, by 2050, it is important to reduce the emissions of future mobile networks, which already account for 2% of global energy consumption. In this context, this research program aims to provide new understanding and guidelines on the design of low emissions and sustainable wireless networks. Particularly, the general objective of this research program is to design, model and analyze wireless networks incorporating relays powered by renewable energy sources with an objective of decreasing the wireless network emissions and improving their sustainability while meeting the quality-of-service requirements of various applications. Specific techniques that will be investigated to achieve these goals include directional antenna relays and reconfigurable intelligent surfaces to reduce the required energy for transmission, and opportunistic relay selection exploiting available renewable energy, spectrum, and channel conditions in different locations. The first outcome of this research project will be novel radio resource management algorithms and medium access control protocols to collect channel and energy statistics, select the optimal relays and configure their parameters (beamforming vectors, spectrum access, etc.), and optimally transmit the information to minimize the network emissions. Both optimal solutions providing theoretical bounds and real-time heuristic algorithms leading to practical implementations and standardization in beyond 5G networks will be proposed. The second outcome of this research project will be network planning methods for the optimal spectrum allocation, deployment and configuration of base stations and relay nodes powered by renewable energy sources to maximize the network sustainability. The third outcome of this research project will be theoretical, analytical, and computer simulation tools to evaluate the network emissions and sustainability of wireless networks integrating relay nodes powered by renewable energy sources. It is therefore expected that the proposed research project will yield significant research contributions to the important area of green wireless networks with a novel understanding on the use and impact of relays with various characteristics and capabilities. Those results will be of interest to wireless service providers, equipment manufacturers, policy-makers, standardization organizations and the research community. As such, it should contribute to the successful deployment of low emission and sustainable wireless networks in the future.

无线服务在我们的社会中发挥着越来越重要的作用，改变着人们的生活、行业流程和社会互动。虽然它们有助于减少二氧化碳排放，例如通过远程办公和提高生产效率，但它们也会导致服务需求增加和经济增长，从而导致二氧化碳排放量总体增加。为了到 2050 年在包括加拿大在内的多个国家实现净零排放，减少未来移动网络的排放非常重要，因为移动网络已占全球能源消耗的 2%。在此背景下，该研究计划旨在为低排放和可持续无线网络的设计提供新的理解和指导。特别是，该研究计划的总体目标是设计、建模和分析包含可再生能源供电的中继的无线网络，以减少无线网络排放并提高其可持续性，同时满足各种应用的服务质量要求。为了实现这些目标，将研究的具体技术包括定向天线中继和可重新配置的智能表面，以减少传输所需的能量，以及利用不同位置的可用可再生能源、频谱和信道条件的机会中继选择。该研究项目的第一个成果将是新颖的无线电资源管理算法和媒体访问控制协议，以收集信道和能量统计数据，选择最佳中继并配置其参数（波束成形矢量、频谱访问等），并以最佳方式传输信息以尽量减少网络排放。将提出提供理论界限和实时启发式算法的最佳解决方案，从而在 5G 网络之外实现实际实现和标准化。该研究项目的第二个成果将是网络规划方法，用于优化频谱分配、部署和配置由可再生能源供电的基站和中继节点，以最大限度地提高网络可持续性。该研究项目的第三个成果将是理论、分析和计算机模拟工具，用于评估集成由可再生能源供电的中继节点的无线网络的网络排放和可持续性。因此，预计拟议的研究项目将为绿色无线网络的重要领域做出重大研究贡献，并对具有各种特性和功能的中继的使用和影响有新的理解。这些结果将引起无线服务提供商、设备制造商、政策制定者、标准化组织和研究界的兴趣。因此，它应该有助于未来低排放和可持续无线网络的成功部署。
