[srslte-users] Version 19.03 PRB 100 issue

[Bilal Maqsood]

Hi SRS team,

I am trying to run srsLTE latest version 19.03 with PRB 100 (20 MHz).

I have eNB and UE running on USRP X310, ubuntu 18.04 and PC is Intel® Core™
i7-7700K CPU @ 4.20GHz × 8,   Ethernet 1GB. Memory 31,3 GiB.

For PRB 100 the UE is not able to connect to the eNB. Below is the console
output and UE log is attached. Please have a look and suggest what could be
the problem.

P.S: I have tried PRB 100 with the older version on same setup and it was
working fine.
