5G (SA) RAN Signaling and Operations Part 2: Network Acquisition
5G_212d | On-Demand | 5G Access | 2
Course Duration: 4 hours
This is the second course in a six-course set of self-paced courses encompassing 5G SA RAN Signaling and Operations. In this course, you will learn about network acquisition for a device in a 5G standalone RAN. You will explore how a device finds and downlink synchronizes with a 5G New Radio cell, reads system information needed for cell selection and uplink synchronization, and establishes dedicated communications with the cell. Each course in this six-course set can stand on its own or can be combined with other courses as necessary to meet your learning objectives.
Intended Audience
5G RAN and device engineering, operations, and performance related job functions
Objectives
After completing this course, the learner will be able to:
■ Describe the steps of preparing to monitor 5G SA cell and 5G network acquisition
■ Summarize the Random Access (RACH) operation
■ Explain the details of RRC connection setup with the gNB
