srsue and gnb compatibility with ZMQ

[iikercosta]

Issue Description

UE does not attach with gNodeB using srsue.

Setup Details

srsue: 22.10

5G core: open5gs

Expected Behavior

gNodeB attaches with open5gs core and the srsue UE too.

Actual Behaviour

gNodeB attaches with open5gs but srsue UE doesn`t.

Steps to reproduce the problem

$ srsue ue.conf

ue.conf.zip

$ gnb -c gnb_rf_zmq_tdd_n78_10mhz.yml

gnb_rf_zmq_tdd_n78_10mhz.yml.zip

I am trying with gNB on x310(band 78 TDD) and srsUE on N310. gNB is able to connect to open5gs core but UE is not able to detect the network. Please let me know if anyone is able to resolve it.

Hi,
the ZMQ protocol used in srsUE (srsRAN 4G) is different to the one used in srsRAN Project. Therefore it is expected to not work. We will release a compatible driver shortly that allows you to use srsUE and srsRAN Project with ZMQ.
With RF it should work, however, only using configs that are supported in srsUE, i.e. try FDD band n3, not TDD n78 with 30 kHz.
