[srslte-users] Listening to UE->eNodeB traffic

[Johannes Becker]

Hello,

I have been able to successfully adapt the pdsch_ue example and compile it thanks to Vasil.
Now, I would like to do the following -- but I am not entirely sure if and how this is possible using a USRP B200:
listen to a downlink (eNodeB->UE) frequency (e.g. 1940 MHz) on one antenna (e.g. "RX2" port)

listen to the corresponding uplink (UE->eNodeB) frequency (e.g. 1860 MHz) on the other antenna (e.g. "TX/RX" port)

identify response messages going from UE to eNodeB

So far, I have heavily simplified pdsch_ue.c to only contain what I need (e.g. removed all the file reading and network logging capability). I am not sure how to approach setting up the second antenna and listening to two channels at the same time though.
Is there a good example somewhere or could someone point me to a resource that describes this?

Thank you!
Johannes
