1、摘要眠状态还是处于工作状态以节省能量是本章研究的问题。本章提出了一种动态规划（DynamicProgramming,DP）的方法来求得所有LPN的最佳工作状态，并且计算复杂度仅与系统资源块数与LPN数的乘积有关。第四章考虑网络中多种业务类型的用户共存时能量效率的提升方法，由于异构网中用户并不是均匀分布在宏小区覆盖范围内的，若按照传统的最大参考信号接收功率（ReferenceSignalReceivedPower,RSRP）来决定用户的接入，将导致大量用户的满意度下降，并且由于某些LPN的资源得不到利用而带来系统能量效率的降低。因此，本章提出了基于消息传递的一
2、种高能量效率的用户接入方法，该方法能有效卸载高负荷小区的业务，使全网资源得到充分的利用，从而带来能量效率的提升。第五章对本文所做的研究作了总结，并且给出了下一步可能研究方向的建议。关键词：异构网能量效率资源分配休眠模式多业务IIABSTRACTABSTRACTAsincreasinglydiversifiedmobilemultimediaservicesofhumanbeings,aswellastherisingdemandfordatarate,thetraditionalcellularsystemscannotmeettheneedsofthem.
