Description

As I just saw https://gerrit.osmocom.org/c/libosmocore/+/17741 I'm wondering how hard it would be to run some simple test (like a ping test with large packet size) over each of the supported CS/MCS.

If we test this against a commercial modem, we should be pretty sure that we don't have any problems in our encoding/decoding of the related messages.

All that would be needed is a way to hard-code (via VTY) the coding scheme for the duration of the respective test.

Any ideas?

AFAIK the CS/MCS to use can already be set through VTY commands like:

pcu
 cs 2
 cs max 2
 mcs 3
 mcs max 3
 cs threshold 10 33
 cs downgrade-threshold 200
 cs link-quality-ranges cs1 6 cs2 5 8 cs3 7 13 cs4 12
 mcs link-quality-ranges mcs1 6 mcs2 5 8 mcs3 7 13 mcs4 12 15 mcs5 14 17 mcs6 16 18 mcs7 17 20 mcs8 19 24 mcs9 23

I have already several tests verifying "initial (M)CS" and "max (M)CS" configs, which can be used to trigger a situation in which both MS and network use specific sets of (MCS) in UL and DL.

So far I'd say in general all look fine, but specifically MCS7-9 should be better tested.
