Chapter 15: Uplink Power and Timing Control

Abstract

Uplink power control and uplink timing control are essential to NR. Power control serves the purpose of controlling the interference, mainly toward other cells as transmissions within the same cell typically are orthogonal. Timing control ensures that different devices are received with the same timing, a prerequisite to maintain orthogonality between different transmissions.
