[srslte-users] srsUE failed at PRACH when connecting to a commercial LTE network

Wed Mar 21 12:09:45 UTC 2018

Hello,

I'm doing my master thesis work and trying to connect srsUE to connect to a commercial LTE network. USRP mini200 is used for radio interface and srsLTE was downloaded and compiled in 17/Mar/2018.

The ue.log shows that srsUE has tried to send PRACH preamble for ten times (the maximum retry from SIB2) without receiving response and then reset the radio link.

Could you help me to figure out what might be wrong? Attached is the ue.log with debug on PHY and MAC level.

I have no access to the network and have no knowledge about what kind of eNodeB it is either. Maybe srsUE can't work probably with the eNodeB.

Thanks in advance!
Br, Shelley
