Burst timing is also passed from osmo-trx to osmo-bts, so should be trivial to pass through.
Yes. I don't know where the TOA value ends up in osmo-bts, but the value is definitely carried per-burst on the socket interface.
For C/I we need a comment from Thomas. Currently we don't have it on the osmo-trx interface and I'm not even sure we calculate it.
We don't have C/I directly. We do have a running average 'noise' level (calculated channel power on non-active uplink slots) and the RSSI value. The channel noise is queried with the NOISELEV command. RSSI is carried per-burst on the socket message. C/I can be calculated from those two values.
Do we need a periodically averaged C/I value or an update every burst?
