Cannot connect srs-ue to srs-gnb using USRP X410 (5G SA)

[bbachmanNI]

Issue Description

Hello, I'm trying to connect a srs-ue to a srs-gnb between two computers over two USRP X410s. The cell selection completes, signal was detected on UE side, but the MIB decoding is not successful with CRC fail (SNR is pretty low)

Setup Details

The srs apps run on 2 separate machine (Dell Precision 5820 with Ubuntu 20.04), UHD 4.4 -> USRP X410

srsRAN_4G UE: at release_23_11 srs-gnb: srsRAN_Project branch main

Expected Behavior

Successful attachment.
