Welcome to O-RAN Part 4: RIC and Apps
5G_113d | On-Demand | 5G Access | 1
Course Duration: 1 hour
This course provides a technology introduction to RAN Intelligence Controller (RIC) Apps and external enrichment in O-RAN operations. You will learn the role of xApps and rApps in O-RAN and the benefits and use of external enrichment data in O-RAN operations. You will also explore how O-RAN can use AI/ML to improve the performance of the RAN.
Intended Audience
This course is designed for a broad audience of personnel working in the wireless industry.
After completing this course, the learner will be able to:
■ Describe the benefits and role of apps in O-RAN operations in Non-RT RIC and Near-RT RIC
■ List role and operations of rApps and xApps in O-RAN management
■ Explain RIC operations for O-RAN performance improvement
■ Describe O-RAN operational use cases
