Hi Tom and List,

we're currently introducing some code that will make more use of
measurement related information associated with the PH-RACH.req and
PH-DATA.ind coming from the PHY up into L2.

The first part is to introduce a reasonable BER limit fo 17% for RACH
ghost elimination, but I have more plans for unifying the measurement
processing/generation accross all supported BTS models.

For osmo-bts-{sysmo,lc15,octphy} it is clear to me how to get the
related information on RSSI, BER and LinkQuality for each of the RACH
and DATA indications from the PHY.

However, how can I get the related information from osmo-bts-trx?

osmo-bts-trx seems to lack any BER reporting toward the common part,
which among other things is the reason why link/rate adaption in the PCU
can not work with it.

Could you sched some light on this?
