Hi， Francisco

Hey, you will have to share the ue and enb logs and console output, otherwise it is impossible to understand what's going on.

Dear all,
i use a COTS ue to connect to srsenb ,when the prb=15,25 or 50, ue can connect to the Internet.But when the prb=75 or 100,ue can not connect to the srsenb and srsenb has no response.
I don't know why, are some parameters not correctly modified? The usrp i use is B210.




Regards,
BIU
