The chapter describes the NR uplink power control and uplink timing control. The similarities and differences to the corresponding LTE mechanisms are high-lighted. Especially, the NR mechanisms for beam-based power control are high-lighted.
Power control; open-loop power control; closed-loop power control; timing control
Uplink power control and uplink timing control are the topics of this chapter. Power control serves the purpose of controlling the interference, mainly towards other cells as transmissions within the same cell typically are orthogonal. Timing control ensures that different device are received with the same timing, a prerequisite to maintain orthogonality between different ...
