[srsran-users] srsran 22.04 - 5G SA on UHD B210 hardware

[Vermeulen, Bas (Consultant)]

Hi Andre,

Could you point me to the parts in the code that need implementing to fix that? We're also interested in using MIMO 2x2 and 4x4, which isn't implemented yet either.

Regards,

Bas Vermeulen

I am afraid that is expected. The UE is very basic and some of the
procedures in RRC connected and idle aren't implemented.

What you can try is to increase the inactivity timer in the eNB so the
UE isn't released too soon.

Thanks
Andre
