使用OAI源码解移动公网下行信号sib1失败

使用ran-develop-sib1-update-ue分支,解移动公网下行信号sib1,decode MIB成功,DCI盲检时CRC校验失败(使用develop分支时也是如此)

nrUE使用命令为:
sudo ./nr-uesoftmodem--sa--numerology1 -r 51 -C 2524950000--ue-rxgain 115   --ue-fo-compensation--ue-scan-carrier --usrp-args"addr=192.168.40.2,clock_source=internal,time_source=internal"   --rrc_config_path ./--nokrnmod --noS1 2>&1 | tee ~/runlog/nr_ue_$(date +%Y%m%d_%H%M%S).log

develop-NR_SA_F1AP_5GRECORDS试试这个分支呢?另外我记得最新的代码是不是UE侧不需要指定--rrc_config_path ./ 了?现在有空口随机接入测试成功的版本吗?

代码中默认是L=4是吗?我用5G OAI UE对接移动公网的基站,也是SIB1的DCI无法译码。
