[srslte-users] PSSCH Issues

[Ahlgren, Isaac]

I appreciate you taking the time to respond. I don't think it's anything to do with sync as I'm just writing to a file and then running that through pssch_ue. I double checked if I'm somehow configuring the PSSCH differently, however, that looks to be fine as well. Do you have any documentation on the steps you were talking about? I'd like to see if I missed a step or something along those lines.

Thanks in advance,
Isaac

what kind of sync are you using and are you sure you have the sync
right? Are you on RF hardware or using files/IP?

There are a few steps involved to get the full transmission right. Note
that the pssch_ue example focuses on receiving COTS C-V2X transmissions
so you would need to replicate those.
