Cooperative performance and resource management in multi-hop, multi-rat wireless access networks

为了应对各种移动宽带业务日益增长的需求，第四代（4G）无线技术考虑提高单位面积频谱效率，通过探索先进的网络拓扑结构，结合先进的通信技术，包括正交频分多址（OFDMA）、网络多用户（MU）、多输入多输出（MIMO），为无线网络提供超越无线电链路改进的下一个性能飞跃。合作/认知通信。这一挑战要求建立一个有效的性能和无线电资源管理框架，该框架应从共同的角度出发，并以合作的方式考虑到现有无线电接入网（ran）提供的资源总量。本研究计划将探讨如何在性能和资源管理基础设施的不同层面引入这种合作概念，以利用不同网络元素共同考虑所产生的频率重用。具体而言，我们将研究和开发多小区、多跳环境下的协作资源分配、传输调度和干扰协调的有效方案，以及多rat异构网络中的协作性能和资源管理策略。研究工作将包括分析和模拟，以开发有效的技术并评估其性能。工业合作伙伴将能够及时获得新开发的方案及其评估性能。我们的研究将有助于下一代无线通信的成功部署，为无线服务提供商提供更好的容量/覆盖范围和用户满意度。该项目将通过培训高素质人员及其与工业界的互动产生一套新的专门知识。拟议的研究意义重大，应该进行这项研究，以提高加拿大在提供无线通信方面的竞争地位。

In response to the growing demand for various mobile broadband services, the fourth-generation (4G) wireless technologies have considered improving spectral efficiency per unit area to provide the next performance leap for wireless networks beyond radio link improvements by exploring advanced network topologies in conjunction with advanced communication techniques including orthogonal frequency division multiple access (OFDMA), network multi-user (MU), multiple-input multiple-output (MIMO), cooperative/cognitive communications. This challenge calls for an efficient performance and radio resource management framework that operates from a common perspective and takes into account the overall amount of resources offered by the available radio access networks (RANs) in a cooperative manner. This proposed research project will explore ways to introduce this notion of cooperation at different levels of the performance and resource management infrastructure to exploit the frequency reuse resulting from the joint consideration of the different network elements. Specifically, we will investigate and develop efficient schemes in cooperative resource allocation, transmission scheduling and interference coordination in multi-cell, multi-hop environments and cooperative performance and resource management strategies in multi-RAT heterogeneous networks. The research work will include both analysis and simulation to develop efficient techniques and to evaluate their performance. The industrial partner will have access to the newly developed schemes and their evaluated performance in a timely fashion. Our research will contribute to the successful deployment of next-generation wireless communications with better capacity/coverage and user satisfaction for the wireless service providers. This project will produce a new set of expertise through training of highly qualified personnel and their interaction with industry. The proposed research is significant, and should be undertaken to enhance Canada's competitive position in providing wireless communications.
