中文摘要： 当前异构small cell网络中用户宏观弹性行为与微观弹性需求凸显,导致弹性干扰复杂和资源管理效率低下等问题。面对弹性用户激增的异构无线网络环境，如何解决其带来的一系列问题、提高网络运行效率变得越来越重要。本课题在以下四个方面展开研究：1）对用户的宏观弹性行为进行挖掘，给宏观弹性行为的定义和量化标准，探讨群体用户的群组博弈建模及弹性用户行为对群组博弈均衡的影响。2）对用户的微观差异化弹性需求进行感知学习，给出不同类型弹性业务用户的行为模型，并给出满足用户差异化需求的资源适配机理。3）基于用户的宏观弹性行为与微观弹性需求，探讨异构网络之间的干扰态势感知策略，并基于感知结果进一步研究分布式的无线资源优化问题，提出抑制弹性干扰的能量效率增强机制。4）针对用户弹性度提高所导致的接入控制和网络选择问题，分析用户网间分布动态，设计弹性感知的网络选择管理机制，实现负载均衡的高效动态弹性接入控制。

英文摘要： Currently, large scale elastic behaviors and small scale diverse requirements in heterogeneous small cell networks (HeSNets) leads to complex elastic interference and inefficient resource management. It's more and more important to solve those problems and improve network operation efficiency when considering elastic users. There are four aspects in this proposal: 1) the users' large scale elastic behaviors are implored, moreover, the definition and formulation of users' group mobility is given, followed with the discussion of the group game's formulation and impact of the user's behavior to the equilibrium. 2) Users' small scale diverse requirements are learned, and the elastic traffic model and suitable resource allocation scheme is proposed. 3) Based on the elastic behaviors, fresh ideas for distributed radio resource allocation based on the sensed interference situation are provided to enhance the energy efficiency. 4) To adapt the users' high elasticity in access control and network selection, users' dynamic distribution is analyzed, and then mobility-aware network selection scheme is investigated to achieve load balanced elastic access control.
