Hey, I was able to solve my issue. Since I’m limited by the 25 MSps sample rate associated with the 1-GigE interface, I lowered my subcarrier spacing to 15kHz from 30 kHz, which lowered my sample rate to 23.04 MSps. However, I received an error from the OAI-Code for having an unknown sample rate.
To solve this, l had to add the 23.04 MSps sample rate to an *if statement* that controlled the configuration of USRP x310s and USRP N300s, and exists within a C++ file that uses the UHD API. I was able to successfully test this on my OAI-nrUE. I will have to make the same change on my OAI-gNB system and test it. On Fri, Nov 19, 2021 at 20:20 Marcus D.
