看log学5G（42）--RRM之资源管理
一、RRM及用途
RRM(Radio resource management-无线资源管理)是无线通信系统(如蜂窝网络、无线局域网、无线传感器系统和无线电广播网络)中同信道干扰、无线资源和其他无线传输系统级管理。

RRM用于发射功率控制、用户分配、波束成形、数据速率、切换标准、调制方案、错误编码方案等参数的策略和算法。

其目标是利用有限的无线频谱资源和网络基础设施提供尽可能高效服务。

二、RRM特点
RRM关注多用户和多小区网络容量问题，而不是点对点信道容量。

高效的动态RRM方案可以将系统频谱效率提高一个数量级，其通常比通过引入先进的信道编码和信源编码方案所能达到的效果要高得多。

RRM在受同信道干扰而非噪声限制的系统中尤其重要，例如蜂窝系统和均匀覆盖大面积的广播网络，以及由许多可能重用相同信道频率的相邻接入点组成的无线网络。

三、5G网络中应用
在5G网络中RRM基于终端(UE)对无线资源的管理，由网络为终端进行灵活分配和动态调整无线(传输)资源；最大程度提高无线频谱利用率，防止网络拥塞并保持尽可能小的信令负荷。

5G(NR) ️非独立组网(NSA)和独立组网(SA)两种架构，无线资源管理中的测量要求也各不相同，具体要求如下
四、5G网络RRM之无线资源管理示例
