The question is - how exactly signal quality is obtained from dsp (on hw with direct dsp access) to osmo-pcu.
The primitives received from the DSP in the sysmoBTS products are not any different on the PCU side than on the BTS side. It's a DATA-indication (GsmL1_PhDataInd_t), and that in turn contains a GsmL1_MeasParam_t member, which has * RSSI * burst Timing * link quality * BER
see http://git.sysmocom.de/sysmo-bts/layer1-api/tree/include/gsml1prim.h for more infoformation.
There is clear difference between l1if_pdch_req() and pcu_tx_data_req() on TX path but what's the equivalent for RX?
I'm not quite sure how the transmit path should ever relate to signal quality measurements?
