Description

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.

History

#1 Updated by arvind.sirsikar about 2 years ago

We have modified osmo-pcu.cfg as below

cs link-quality-ranges cs1 6 cs2 5 8 cs3 7 13 cs4 12

TO

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
