Bug #3526
closed
trxcon: L1CTL_DM_EST_REQ is not handled properly when requested ARFCN != the current
Added by fixeria over 5 years ago.
Updated almost 5 years ago.
Description
It was noticed that if BSC allocates a dedicated (e.g. TCH) channel on an ARFCN that is different
from the one mobile is currently camped to, trxcon would fail to follow this assignment.
I just found out that ARFCN indicated in L1CTL_DM_EST_REQ is merely not handled by trxcon :/

I'll try to do that tomorrow, when I'll have access to the tester.
This is not as simple as just running the test as the receiver needs to
be extended so it's able to work without constant synchronization from
SCH. For now I can try to use normal bursts, but I won't do this today
as I have other things planned to do.
Probably it would be good to enable correction of sample rate offset
correction. It was disabled because it complicates Rx and Tx
synchronization - so this part would also have to be improved.
- Status changed from Feedback to Stalled
Yep, I also just realized this...
Makes sense to create a separate issue for GR-GSM.
- Status changed from Stalled to Resolved
- % Done changed from 40 to 90
For gr-gsm it makes sense to create a separate issue.
The fix for trxcon has been merged, so I am closing.
