前传感知的数据链路层和物理层之下行链路 | 带你读《5G系统关键技术详解》之十五

第 3 章云无线接入网络的前向回传感知设计 3.3 前传感知的数据链路层和物理层 3.3.1 上行链路 3.3.2 下行链路在本节中，我们考虑在 D-RAN 系统的下行链路的 RRH 处进行控制的低延迟 HARQ 协议。类似于上行链路的情况，关键思想是使 RRH 能够进行低延迟重传控制决策，同时...

前传感知的数据链路层和物理层之上行链路 | 带你读《5G系统关键技术详解》之十四

第 3 章云无线接入网络的前向回传感知设计 3.2 前传感知的协作传输和接收 3.3 前传感知的数据链路层和物理层到目前为止，我们已经讨论了前传容量限制对 C-RAN 频谱效率的影响。本节涉及延迟，这是同样重要的影响 5G 部署性能的系统目标。一个重要的例子是跨越数据链路和物理层运行并通过衰落信...

灵活的物理层设计 | 带你读《5G系统关键技术详解》之二

第 1 章 5G 系统新技术的概况 1.4 非正交多址接入 1.5 灵活的物理层设计如 1.1 节所述，5G 网络旨在不仅支持语音和移动互联网应用，还支持 IoT、M2M、触觉互联网和车载通信等应用。这些应用在延迟、可靠性和功耗方面都有不同的要求。在过去十年里，正交频分复用（OFDM，Orth...
