Low-cost, application-aware, high-fidelity methods for 5G systems and beyond

移动的网络目前正处于前所未有的业务增长和消费者兴趣的时代。为了解决带宽供需之间的不匹配，即将到来的第五代（5G）网络必须具有更强大和更可靠的数量级。预计这将需要越来越多样化的技术，包括异构网络、致密化、大规模多输入多输出（MIMO）以及可能的毫米波系统。此外，在下一代，移动的网络将被要求维持新形式的流量，例如许多（可能是数百万）低功耗设备相互通信。满足5G网络的要求，并超越5G，提出了巨大的挑战。最近的大部分研究都集中在从设备供应商的角度设计无线网络，但相对较少关注无线供应商的问题，如我们的工业合作伙伴TELUS。像TELUS这样的服务提供商必须应对不断增长的应用和用户需求的广泛变化，例如可能的低速率物联网（IoT）[3]，设备到设备（D2 D）通信[4]，语音（4G LTE提供LTE语音或VoLTE）[5]以及极高速率的增强型多媒体广播。在这项提案中，我们直接解决这些挑战，追求两个研究主题：在第一个主题中，我们将调查一些关键方面的使用未授权频段，这是免费使用，并可能提供更多的带宽比传统的授权频段。我们将解决传统服务的干扰问题以及物联网和D2 D通信等新服务使用未授权频段的关键问题。在我们的第二个主题中，我们将从两个角度研究优化许可频谱的使用-有效的应用感知资源分配和调查大规模无线网络中的实际问题。

Mobile networks are currently in an era of unprecedented traffic growth and consumer interest. To account for the mismatch between bandwidth supply and demand, the upcoming fifth generation (5G) of networks must be orders of magnitude more capable and reliable. This is expected to require increasingly diversified technologies, including heterogeneous networks, densification, massive multiple-input, multiple output (MIMO), and possibly millimeter-wave systems. Moreover, in the next generation, mobile networks will be required to sustain new forms of traffic such as many, potentially millions of, low-power devices communicating with each other.Meeting the requirements of 5G networks, and looking beyond 5G, raises enormous challenges. Much of the recent research has focused on the design of wireless networks from an equipment vendor's perspective, but relatively little has focused on the problems of wireless providers, such as our industrial partner, TELUS. Service providers like TELUS must contend with a growing proliferation of applications and wide variations in users' demands, such as likely low-rate internet of things (IoT) [3], device to device (D2D) communication [4], voice (4G LTE provides for Voice-over-LTE or VoLTE) [5], and extremely high-rate enhanced multimedia broadcast. In this proposal, we directly address these challenges pursuing two research themes: in the first theme, we will investigate a few key aspects of in the use of unlicensed bands, which are both free to use and potentially provide more bandwidth than conventional licensed bands. We will address the key issue of interference for conventional services and the use of unlicensed bands for new services like IoT and D2D communications. In our second theme, we will investigate optimizing the use of licensed spectrum from two points of view - effective application aware resource allocation and investigating practical issues in large-scale wireless networks.
