Introduction to Open RAN xApps / rApps
Open RAN xApps and rApps are software applications designed to enhance and optimize the operations of Radio Access Networks (RANs) within the Open Radio Access Network (Open RAN) architecture. xApps operate in the near-real-time RAN Intelligent Controller (near-RT RIC), making decisions in the order of milliseconds to seconds, and are primarily focused on RAN optimization and control. rApps run on the non-real-time RIC (non-RT RIC), with a broader decision-making window, typically seconds to minutes, and are concerned with RAN management and policy guidance. Examples include dynamic spectrum management, load balancing, interference detection and mitigation, and energy savings. These applications leverage the openness and programmability of the RAN to implement intelligent, adaptive control strategies, and policies, thereby improving network efficiency, performance, and flexibility.
