【摘要】：面向绿色移动通信而提出的超蜂窝网络架构,是建立在以业务和控制覆盖分离为核心的柔性覆盖基础上的,本文重点研究了控制与业务覆盖的分离覆盖架构,给出了分离覆盖的原则以及分离覆盖的条件和实例,并在此基础上,就控制过程的两个核心问题展开研究.针对部分信道观察下的信道预估问题,结合基于环境学习的信道预测机制,利用信道的时间和空间相关性,分别提出了基于业务基站周期开启测量进行测量与服务决策,以及基于离线信道学习和在线部分观察的信道空间预估方法.针对控制覆盖的大容量接入问题,通过将稀疏码多址(SCMA)非正交多址接入用于非授权接入技术的方案,并进一步改进发送和接收方法,可有效支持控制覆盖所需的大容量、低时延、高可靠的短包控制接入.
[Abstract]:The super-cellular network architecture for green mobile communication is based on the flexible coverage which is based on the separation of service and control coverage. This paper focuses on the separation of control and service coverage. The principle of separation coverage, the conditions and examples of separation coverage are given. On the basis of this, two core problems of control process are studied. Combined with the channel prediction mechanism based on environment learning and the correlation between time and space of the channel, the measurement and service decision based on the cycle opening measurement of the service base station are proposed respectively. And channel space estimation method based on off-line channel learning and on-line partial observation. Aiming at the large capacity access problem of control coverage, the scheme of using sparse code multiple access (SCMA) non-orthogonal multiple access (SCMA) for unauthorized access technology is proposed. Furthermore, the method of sending and receiving can be improved to effectively support the large capacity, low delay and high reliable short packet control access required by the control coverage.
