1、看1oG学5G(64)-NSA网络中的B1测量#5G#NSA#B1测量一、NSA架构中B1测量5G在NSA组网架构下终端(UE)从eNodeB接入后，通过对5G(NR)的B1测量选取信号质量最好的5G(NR)邻区后，可将5G(NR)邻区所属的gNodeB添加为辅站。其中5G(NR)的B1测量流程如下图所示：图1NSA中B1测量流程二、B1测量流程在NSA网络中终端(UE)接收网络侧的B1配置，执行测量，按照报告要求上报B1测量结果；它们通过以下三步来实现：1. eNodeB向UE下发“RRCConnectionReconfiguration消息(消息中包含NRB1测量控制信息)，对相邻的NR小

2、区进行测量。2. UE发送RRC重配置完成消息，通知eNodeBNRB1测量配置完成。3. UE向eNodeB上报测量报告，测量报告中包含了NRB1测量的结果三、NSA网络B1测量和上报消息实例3.1 B1测量控制信息,这是eNodeB给终端下发包括B1的测量控制消息。TimeSourceChanne1Direction19:52:51235MSINASMSeNo.19:52:51239MSIUt-D.MS-eNo.19:52:51240MSIU1-D.MS-eNo.aMessageaAttachCofnpIeteRRCConnectionRecoonCfnp1eU1InfonmetionTr
