中文摘要： 异构云小区网络由于其部署灵活、耗能低、资源弹性管理、用户能力增强等优势，成为未来5G研究热点。为弥补用户终端硬件不足，异构云小区需要分担终端的计算任务，缓解其计算压力，这将导致终端对相关数据的计算时延较为敏感。合理的分配网络资源能够降低计算时延。然而，目前在异构云小区网络中针对时延问题的资源分配方案较少。此外，当考虑用户移动、天线分配、多媒体业务传输、能量效率优化等因素时，要保证用户计算时延，实现网络性能的显著提升，还有一些新的技术问题亟待解决。本课题拟围绕异构云小区网络中的资源配置方法展开研究，以计算时延保证的核心目标，分别设计计算及无线资源联合分配策略、下行传输配置方案以及上行传输配置方案，为异构云小区网络更高效的完成计算任务、更可靠服务用户和更科学的管理资源提供理论依据。

英文摘要： Heterogeneous Cloud Small Cell Networks (HCNet) have attracted much attention due to its advantages such as feasible deployment, low energy consumption, user capacity enhancement and so on. To complement mobile terminals’ hardware limitation, HCNet can be used to support mobile terminals. In this text, mobile terminal can be sensitive to the computation delay. Reasonable resource allocation can help reduce the computation delay, however, less work has been done on this area. Moreover, when combing computation delay with factors such as terminals’ mobility, antenna, multimedia transmission, energy efficiency optimization, new technology issues will occur. In this work, with the aim of optimizing computation delay, joint computation and wireless resource allocation strategy, downlink transmission reconfiguration method and uplink transmission reconfiguration schemes are studied and proposed. Furthermore, theoretical basis is provided for efficient computation, reliable user service and reasonable resource management.
