Understanding xApp and rApp for Automated Management of 5G O-RAN Private Networks

Hello,

I would like to request information about xApp and rApp and their role in the automatic management of 5G O-RAN private networks. Specifically, I am interested in understanding their functions, how they integrate with the RIC (RAN Intelligent Controller), and their impact on optimizing network performance and automation. Any insights or resources on this topic would be greatly appreciated.

Thank you!
