Attempt to fix `nr-dlsim` Test 21 (4x4 MIMO, 2 Layers)
Nice catch by Francesco Mani
oai-nr-dlsim
may seem fine but in fact, test21
may or may not be executed. On some run example, we do not have finished
message on nr-dlsim
pod.
I've put a fail criteria if we face time out.
The CI commit was merged.
But the fixes that Francesco made on the DL trigger an assertion on gNB
in the NSA module.
