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.

响应于对各种移动的宽带服务的不断增长的需求，第四代（4G）无线技术已经考虑通过结合包括正交频分多址（OFDMA）、网络多用户（MU）多输入多输出（MIMO）、协作/认知通信。这一挑战需要一种高效的性能和无线电资源管理框架，该框架从共同的角度进行操作，并以协作的方式考虑由可用无线电接入网络（RAN）提供的资源的总量。这个拟议的研究项目将探讨如何在不同级别的性能和资源管理基础设施，利用频率复用不同的网络元素的共同考虑所产生的合作的概念。具体而言，我们将研究和开发有效的方案，在合作的资源分配，传输调度和干扰协调在多小区，多跳环境和合作的性能和资源管理策略在多RAT异构网络。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的绩效。我们的研究将有助于成功部署下一代无线通信，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。拟议的研究是重要的，应进行，以提高加拿大在提供无线通信的竞争地位。
