Hello, I also tried to establish a 5G SA connection between srsue and Amari callbox. However, it cannot make a connection. srsUE just repeat below sentence.
RF Status: O=16, U=0, L=0
So, can I ask your config file of srsUE and Amarisoft gnb? Also, is there some condition to succeed connection?
Issue Description
Hi all,
I am trying to establish a 5G SA connection between srsUE and Amarisoft Callbox. The connection is unstable and I see a lot of "Error filing tb" and "Computing UL grant" prompts.
It works when I fix the low mcs (mcs=8, for 10MHz bandwidth and 15kHz scs) at the base station. Does that mean my UE is not able to generate data fast enough?
Setup Details
Intel Core i7 CPU @ 3.50 GHz 8GB RAM Ubuntu 20.04.1 srsRAN 22.04 UHD v4.2.0.0
Expected Behavior
no errors
Actual Behaviour
UE output: Active RF plugins: libsrsran_rf_uhd.so libsrsran_rf_zmq.so Inactive RF plugins: Reading configuration file /home/user/.config/srsran/ue.conf...
