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起着越来越重要的作用，改变了人们的生活，行业过程和社会互动。尽管它们有助于减少二氧化碳排放，例如，远程办公和生产效率提高，它们也会导致服务需求和经济增长的增加，从而导致二氧化碳排放量的总体增加。为了在包括加拿大在内的几个国家 /地区达到零排放的目标，到2050年，重要的是减少未来移动网络的排放，这已经占全球能源消耗的2％。在这种情况下，该研究计划旨在提供有关低排放和可持续无线网络设计的新理解和指南。特别是，该研究计划的一般目标是设计，建模和分析由可再生能源提供动力的无线网络，目的是减少无线网络排放并改善其可持续性，同时满足各种应用程序的服务质量要求。将研究以实现这些目标的特定技术包括定向天线继电器和可重新配置的智能表面，以减少传输所需的能量，并利用可用可再生能源，频谱和不同位置的渠道条件利用的机会性继电器选择。该研究项目的第一个结果将是新型的无线电资源管理算法和中等访问控制协议，以收集渠道和能量统计，选择最佳继电器并配置其参数（波束成形向量，频谱访问等），并最佳地传输信息以最大程度地减少网络发射。提供理论界限的最佳解决方案和实时启发式算法，从而在超越5G网络中实现实际实现和标准化。该研究项目的第二个结果将是用于最佳频谱分配，基本站的部署和配置以及由可再生能源供电的基础站和继电器节点的最佳分配和配置的网络计划方法，以最大程度地提高网络可持续性。该研究项目的第三个结果将是理论，分析和计算机仿真工具，以评估无线网络的网络排放和可持续性集成由可再生能源提供支持的中继节点。因此，预计拟议的研究项目将对绿色无线网络的重要领域产生重大的研究贡献，并对具有各种特征和能力的继电器的使用和影响有新颖的了解。这些结果将引起无线服务提供商，设备制造商，决策者，标准化组织和研究社区的关注。因此，它应该在未来成功部署低排放和可持续的无线网络。
