With the emerging prevalence of new bandwidth-hungry applications, such as mobile social networking, wireless multimedia, and Internet of Things, the latest-generation wireless service infrastructure is already facing severe resource shortage in its struggle to satisfy the exploding service demands. In response, a heterogeneous multi-tier wireless networking paradigm, where smaller and autonomous cells and relays are deployed concurrently with the traditional macro cells, have been promoted by system designers and network operators. There are many challenges in the design and deployment of multiple tiers of overlapping base stations and relays, especially under the stringent data-rate and signal-to-interference requirements imposed by ever popular immersive and interactive multimedia applications. In particular, radio interference is expected to be a key barrier to desirable coverage and capacity in the next-generation heterogeneous wireless systems. Innovative interference management techniques are needed to counter the extremely complex radio activity patterns generated by the diverse, autonomous, and dynamic set of transmitters in the multi-tier environment. In collaboration with Ericsson, one of the largest telecommunication innovators in the world with a strong research and business presence in Canada, we will investigate into the theories and practical designs for interference management in next-generation multi-tier heterogeneous wireless networks. Intelligent interference suppression and mitigation schemes will allow efficient utilization of the limited radio resources despite the complex heterogeneity in future systems and provide optimal service experience to the end users. We will generate practical guidelines on how to design and operate future heterogeneous wireless systems, to optimally balance the tradeoff between service performance and networking cost. The outcomes of this research are expected to benefit both our industry partner and the Canadian information and communication industry at large, by promoting engineering theory, technical methods, and standardization policies that can lead to system improvement, cost reduction, sustainable growth, and long-term competitiveness.

随着移动社交、无线多媒体、物联网等新的高带宽应用的兴起，最新一代的无线服务基础设施在满足爆炸式增长的服务需求时已经面临着严重的资源短缺。作为回应，系统设计者和网络运营商已经推广了异构多层无线网络范例，其中较小的自治小区和中继与传统宏小区同时部署。多层重叠基站和中继的设计和部署面临许多挑战，特别是在流行的沉浸式和交互式多媒体应用提出的严格数据速率和信号干扰比要求下。特别是，无线电干扰预计将成为下一代异构无线系统中实现理想覆盖范围和容量的主要障碍。需要创新的干扰管理技术来应对多层环境中多样化、自主和动态的发射机集产生的极其复杂的无线电活动模式。我们将与爱立信（世界上最大的电信创新者之一，在加拿大拥有强大的研究和业务实力）合作，研究下一代多层异构无线网络中干扰管理的理论和实践设计。尽管未来系统存在复杂的异构性，但智能干扰抑制和缓解方案将允许有效利用有限的无线电资源，并为最终用户提供最佳的服务体验。我们将制定有关如何设计和操作未来异构无线系统的实用指南，以最佳地平衡服务性能和网络成本之间的权衡。这项研究的成果预计将使我们的行业合作伙伴和整个加拿大信息和通信行业受益，通过推广工程理论、技术方法和标准化政策，从而改善系统、降低成本、可持续增长和长期竞争力。
