5G (SA) RAN Signaling and Operations Part 5: Uplink Data Transfer
5G_215d | On-Demand | 5G Access | 2
Course Duration: 4 hours
This is the fifth course in a six-course set of self-paced courses encompassing 5G SA RAN Signaling and Operations. In this course, you will learn about uplink data transfer from a device to a gNodeB. You will explore how the device requests to be scheduled for uplink resources, how the gNodeB does resource allocation for uplink data, and how power control is used to meet uplink signal quality requirements. 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:
■ Explore the role of beamforming in UL traffic operations
■ Step through the procedures of Scheduling Request and Buffer Status Report
■ Step through the resource allocation and power control for the uplink
■ Explore RRC signaling messages and parameters for the uplink operation
