AI Technical Summary

Technical Problem

In frequency bands above a certain frequency, phase noise and peak power are highly sensitive to the average power ratio (PAPR), and existing technologies have not adequately studied how to control communication.

Method used

Communication control is optimized by adjusting the time, frequency, and spatial resource allocation of the control resource set and by employing various modulation schemes and channel designs, including wide subcarrier spacing structures, beam loops, frequency hopping, and multiple TCI states.

Benefits of technology

Effective communication control was achieved in the high-frequency band, reducing the impact of phase noise and PAPR, and improving communication quality.
