Hi shuimoshuseng,

Do you mean how to get the PDCCH parameters needed to run the code from the SIB information you attached? I added Detailed instructions in the README of the project some time ago, did that help you? The instructions include the equivalence between parameters and the RRC parameter names.

You might need to check some additional resources to understand basic parameters such as downlinkBWP and so on.

Okay, I will check the README file you wrote later. Thank you🤝
