A new test case 5g_zmq_radio_trs is created by copying the folder 5g_zmq_radio_1x1. A gnuradio python script (rotate_zmq.py) generated by grc is used to read the samples from gNB and apply a freq drift and send them to a ZMQ sink. The UE reads samples from the ZMQ port on gnuradio. The gnuradio script is modified to receive message containing freq offsets from another script (send_freq_offset_zmq.py). Dockerfile.gnuradio builds an ubuntu 24.04 image and copy both python scripts. Modified the docker-compose.yaml to include a new service gnuradio-zmq that starts by running rotate_zmq.py. Created container_5g_zmq_ocudu_trs.xml by copying container_5g_zmq_ocudu_1x1.xml. Included a Custom_Command to run send_freq_offset_zmq.py and another custom_command to grep the UE stdout for TRS freq correction. Added a PUSH socket in zmq_radio.cpp to send carrier frequency to gnuradio and remove the offset applied so that the test can continue without a freq offset.
