中文摘要： 无论是从绿色环保的国际大背景出发，还是从蜂窝通信发展的现实需求出发，实现能效优先、兼顾其它QoS的中继蜂窝网络都有着非常重大的意义。然而，当前中继蜂窝网络存在着能效度量不明、资源分配不当、干扰管理不力等问题。针对这样的研究现状，本项目拟从能效度量、资源分配和干扰管理等角度出发，为能效优先的中继蜂窝网络建立完备的分析模型，并提出切实可行的实现算法。具体研究内容如下：1）能效度量：建立能效度量准则，为后续资源分配和干扰管理提供理论指导和性能评估依据，包括a）基于综合QoS的能效度量准则，b）基于能效增益的性能评估方法；2）资源分配：提出能效优先的资源分配算法，有效解决中继蜂窝网络中资源分配不当的问题，包括a）低交互的资源分配，b）多目标的资源优化；3）干扰管理：设计能效优先的干扰管理机制，有效解决中继蜂窝网络中干扰管理不力的问题，包括a）高能效的频率规划，b）低能耗的信号处理。

英文摘要： Not only the international background of green and environmentalism, but also the practical requirement of cellular networks, makes it very important to realize energy-optimized and other QoS-guaranteed relay cellular networks. However, such problems as nonspecific metric of energy efficiency, improper resource allocation, and inefficient interference management exist in nowadays relay cellular networks. In light of the status in quo, the project, aiming at the energy efficiency measures, resource allocation, and interference management, will try to build complete analysis model for the energy-optimized relay cellular networks, and propose practical implementation algorithms. Firstly, the metric of energy efficiency will be established to serve as the theoretical guideline for latter resource allocation and interference management, including the measuring criteria for energy efficiency based on integrated QoS and the performance evaluation method based on energy efficiency gain. Secondly, energy-optimized resource allocation algorithms will be proposed to solve the problem of improper resource allocation, including low-exchange-overhead resource allocation and multi-criteria resource optimization. Finally, energy-optimized interference management mechanisms will be designed to solve the problem of inefficient in
