UPLINK MCS gets reduced from MCS9->MCS6 when good radio condition exists
During EGPRS UL testing with osmo-trx setup, it is seen that MCS gets reduced very fast even when radio condition is good. Same issue is present for GPRS testing as well.
This condition exists only with osmo-trx setup.

We have modified osmo-pcu.cfg as below
cs link-quality-ranges cs1 6 cs2 5 8 cs3 7 13 cs4 12
cs link-quality-ranges cs1 0 cs2 0 8 cs3 0 13 cs4 0
and validated in integration setup. further investigation needs to be done on how measurement parameter is conveyed between TRX and PCU apart from the usual DATA-IND message
- Status changed from New to Feedback
IIUC this issue was expected until recently when we started providing and fixing
measurement values from osmo-trx through osmo-bts-trx into osmo-pcu.
fixeria what do you think?
ACK. This should not happen anymore, but we need a TTCN-3 test case to be sure.
arvind.sirsikar, could you please test with the current master and update the issue? Thanks!
