第1章 基站配置文件概述
1.1 基站配置文件的作用
配置文件是对基站进行配置的文件，基站要能够正常工作，必须要有大量的参数配置。
通过文件对基站进行配置是一个比较快捷的方式。
每个配置文件，代表一种网络部署！！！
1.2 配置文件的路径
（1）存放路径：
/root/oai/openairinterface5g/targets/PROJECTS
CENTOS-LTE-EPC-INTEGRATION： ???
GENERIC-LTE-EPC：连接LTE EPC的配置
GENERIC-NR-5GC：连接5G核心网的配置
（2）CENTOS-LTE-EPC-INTEGRATION/conf
enb.centos.calisson.conf
enb.centos.memphis.conf
enb.centos.nord.conf
（3）GENERIC-LTE-EPC/conf

1.3 配置文件名解读
- cu/du/gnb/enb：指明设备的部署类型
- sa：5G独立部署
- bandxx：频段
- fr1 or fr2：5G 频谱区间
- tmx：传输模式
- PRB: 分配给SCH信道的PRB个数
- usrpbxxx：OAI支持的实际RF硬件的型号，目前OAI只支持usrpb系列硬件。
- nfapi：PNF和VFN部署中，VFN的对外接口是nfapi，而不是RF.
1.4 配置的使用
通过-O选项指明配置文件的全路径，如下示例所示：
sudo RFSIMULATOR=server ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-LTE-EPC/CONF/gnb.band78.tm1.106PRB.usrpn300.conf --parallel-config -d PARALLEL_SINGLE_THREAD --rfsim --phy-test --noS1 --nokrnmod 1
1.5 配置文件与命令行选项的关系
（1）配置文件必须通过命令行选项指定
（2）部分命令行选项可以覆盖配置文件的设置
（3）大部分配置参数，无法通过命令行选项重新配置，命令行选项是配置文件的一个子集。
