AI Technical Summary

Technical Problem

In next-generation wireless communication systems, determining appropriate power control parameters for uplink transmission based on transmission configuration indication (TCI) states is crucial to maintain communication quality and throughput, but existing methods lack sufficient study on the relationship between TCI states and power control parameters, risking deterioration in performance.

Method used

A terminal and wireless communication method that includes information on multiple TCI states and power control parameters for uplink transmission, with a control unit determining these parameters to ensure appropriate power control, utilizing a unified TCI framework to apply common TCI states to both downlink and uplink channels, and associating TCI states with P0/alpha/closed loop index settings to optimize power control.

Benefits of technology

This approach allows for accurate determination of power control parameters, enhancing communication quality and throughput by aligning TCI states with power control settings, thereby stabilizing uplink transmission in next-generation wireless systems.
