The downlink looks good. Check the UL on the eNB, I guess UL signal too weak or strong.
Issue Description
srsue unstable behaviour with usrp x310 in LTE mode.
Setup Details
[Specify details of the test setup. This would help us reproduce the problem reliably] We have 2 usrp x310s running UHD 3.15 and the latest release version of srsRAN. We specified the device arguments as the following.
The rest are set to their default values.
Expected Behavior
srsUE attaches to the network.
Actual Behaviour
srsue keeps getting stuck on attaching to UE after finding the cell. Sometimes it does successfully attach, but it is inconsistent. However, the srsenb works with COTS UE (Samsung S20 Ultra 5G) using a sysmocom SIM.
Steps to reproduce the problem
Here is the UE log file. ue.log
Since COTS UE works, I'm not sure what the issue is with srsUE.
