Q: I have deduced that RXQ is referenced in abis_rsl.c in the bsc, is it just propagated from the sdr up through Transceiver, where is the actual evaluation done?
The measurement values are computed by OsmoBTS. The raw values are paseed from the BTS-specific part (osmo-bts-trx in your case) via the L1SAP MPH_INFO indication (sub-type PRIM_INFO_MEAS) to the common part in src/common, where measurement.c is performing the bulk of the computation.
The values are then reported on Abis every SACCH multiframe as part of the RSL MEASUREMENT INDICATION messages to the BSC, which uses them as input for e.g. handover decision making.
