[srslte-users] SRS UE connecting to commercial network

[Saimanoj Katta]

Hello Andre,

Sorry for the late reply. I get a clean signal when I execute pdsch_ue as
you advised me to check.
When I run srsue, it even detects a cell, but, the index values start to
appear and the error keeps happening-

Found Cell:  Mode=FDD, PCI=12, PRB=25, Ports=2, CFO=0.3 KHz
Invalid inputs rv_idx=-1, cb_idx=15
/home/ubuntu/srsLTE/lib/src/phy/phch/sch.c.343: Error in rate matching

Invalid inputs rv_idx=-1, cb_idx=15
/home/ubuntu/srsLTE/lib/src/phy/phch/sch.c.343: Error in rate matching

^Z
[7]+  Stopped                 srsue --rf.dl_earfcn 2875 --log.all_level=info

It always, asks MAC to look for SIB1(Attached are the logs). In eNB
configuration, S1B1 is not configured. To configure it in eNB, it takes a
huge time, I understand. Is it easier to disable it in the code and start
working to recieve SIB2?  I am a beginner to this platform and I am
confused, what to do next.

Regards,
Saimanoj
