Since the development of 4G LTE standards around 2010, the research communities both in academia and industry have been brainstorming to predict the use cases and scenarios around 2020, to determine the corresponding technical requirements, and to develop the enabling technologies, protocols, and network architectures towards the next-generation (5G) wireless standardization. This exploratory phase is winding down as the 5G standardization phase approaches. The first wave of 5G standards are expected to be developed during the 2017-18 timeframe, to be approved by ITU during the 2019-2020 timeframe, and to become operational in the early 2020s. As such, it is time to reinitiate a similar brainstorming endeavour towards the beyond-5G wireless networks; we refer to such networks as 5G+ in order to include the evolution of the 5G standards in 2020s and to perform the groundwork for those to be developed towards 2030. The proposed research program is geared towards the fundamental problem of the supply-demand mismatch in 5G+ wireless networks. This problem has different significance based on the context and discipline. In the wireless context, the supply is the potential rate that the access network can provide and the demand is the traffic generated by the users and devices. If the total demand in space and time is less than the total potential supply, this results in an obvious shortage. In this case, there is little that can be done, except for either reducing the demand or increasing the supply, or both. A more interesting and relevant case occurs when the network experiences shortage (congestion) despite the total potential supply (in space and time) exceeds the total demand (in space and time). This situation manifests itself when there is a mismatch; i.e., when the demand does not arise where the supply is. In order to analyze the severity of the mismatch problem, it should be checked whether the supply can be storable (in time) or transportable/transferable (in space) in an efficient manner. If the answer is yes to these questions, then the mismatch problem can easily be alleviated. On the other hand, a negative answer signals a difficult problem. In wireless networks, the supply-demand mismatch constitutes a highly critical and serious situation due to the fact that, in general, the supply can neither be stored nor transported. Within the very broad 5G+ paradigm, the objective of the proposed research program is two-fold: Theme I: Developing models to capture the highly heterogeneous traffic scenarios of the future. Theme II: Developing novel and possibly disruptive solutions to alleviate the impact of the resulting unprecedented congestion scenarios in HetHetNets. The proposed research program will contribute to Canada's remaining as an important and competent player in the global ICT area with the creation of the necessary knowledge base and the training of highly-qualified personnel.

自2010年左右建立4G LTE标准以来，学术界和行业的研究社区一直在集思广益，以预测2020年左右的用例和场景，以确定相应的技术要求，并开发促成技术，协议和网络体系结构，以实现下一代无线标准化。 随着5G标准化阶段的接近，这个探索阶段正在结束。预计将在2017 - 18年度期间制定5G标准的第一波浪潮，并将在2019 - 2020年期间获得ITU的批准，并在2020年代初开始运营。因此，是时候重新引起对超过5G无线网络的类似的头脑风暴努力了。我们将这样的网络称为5G+，以包括2020年代5G标准的演变，并为2030年开发的基础工作。 拟议的研究计划旨在解决5G+无线网络中供求不匹配的基本问题。根据上下文和纪律，此问题具有不同的意义。在无线上下文中，供应是访问网络可以提供的潜在速率，需求是用户和设备产生的流量。 如果空间和时间的总需求小于总潜在供应，则这会导致明显的短缺。在这种情况下，除了减少需求或增加供应或两者兼而有之，几乎没有什么。当网络经历短缺（拥塞），尽管总潜在供应（在时空和时间上）超过了总需求（在时空和时间上），但会发生一个更有趣和相关的情况。当存在不匹配时，这种情况就显现出来。即，当未在供应所在的地方出现需求时。为了分析不匹配问题的严重程度，应检查供应是否可以（及时）存储或可运输/可转移（在太空中）有效。如果答案对这些问题是肯定的，那么不匹配的问题很容易得到缓解。另一方面，负面答案标志着一个困难的问题。在无线网络中，供求不匹配构成了一个高度危急和严重的情况，因为总体上，供应既不能存储也可以被存储。 在非常广泛的5G+范式中，拟议的研究计划的目的是两个方面： 主题I：开发模型以捕捉未来的高度异构交通情况。 主题II：开发新颖的和可能具有破坏性的解决方案，以减轻hethetnets中前所未有的拥塞场景的影响。 拟议的研究计划将通过创建必要的知识库和训练高度合格的人员的培训，为加拿大作为重要而有能力的参与者的剩余参与者。
