AI Technical Summary
In 5G systems, how terminal devices can effectively control the transmission power of multiple uplinks to improve system performance is an urgent problem.
The terminal device determines its actual transmission power according to the desired transmission power of each uplink and ensures that the sum of the actual transmission power is not greater than the maximum transmission power allowed by the terminal device. The specific method includes calculating the actual transmission power based on the desired transmission power and the maximum transmission power, or power adjustment through adjustment factors or adjustment amounts.
This method helps to improve the transmission power utilization of terminal equipment, improve system performance, and ensure the stability and efficiency of the system.
