5G User Equipment Power Adjustment for Internal Noise Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing power consumption in 5G and NR communication systems due to high carrier frequencies and large bandwidths is exacerbated by internal noise in user equipment, leading to inefficient power usage and reduced communication performance.
Innovation Solution
A method to determine whether internal noise is a dominant factor in user equipment by analyzing capability information, and adjust transmission power accordingly to optimize power usage and improve communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmission power is increased to improve communication performance in 5G/NR systems, then data service quality is improved, but power consumption of the network and base station increases
Solution Approach 1:
The patent adjusts transmission power parameters dynamically based on the determined dominant noise factor. When internal noise is dominant, transmission power is reduced to save energy while maintaining adequate communication performance. When external interference is dominant, transmission power is increased to overcome interference. This parameter adaptation resolves the contradiction by making power consumption dependent on actual channel conditions rather than using fixed high power.
2Reliability
If transmission power is increased to overcome internal noise in user equipment, then communication performance is improved, but wasted power increases when internal noise is not the dominant factor
Solution Approach 1:
The patent implements a feedback mechanism where the base station determines the dominant noise factor (internal or external) based on capability information from user equipment and channel conditions. This feedback loop enables dynamic adjustment of transmission power: when internal noise is dominant, power is increased to compensate; when external interference is dominant, power is maintained or reduced. This prevents wasted power by avoiding unnecessary power increases when they would not improve communication performance.
3Productivity
If high carrier frequencies and large bandwidths are used to provide ultrahigh speed data services, then data capacity is improved, but power consumption of the network increases
Solution Approach 1:
The patent introduces dynamic transmission power adjustment based on real-time noise condition assessment. While 5G/NR systems use high carrier frequencies and large bandwidths to achieve ultrahigh data capacities, the system dynamically adapts transmission power levels rather than maintaining constant high power. When internal noise is the dominant constraint, power is reduced to minimize energy consumption. This dynamic approach maintains high data capacity capability while reducing actual power consumption to match operational needs.

AI summary
Provided are a user equipment and an operation method of a wireless communication system including the user equipment, the user equipment allowing power consumption of a network (or base station) to be reduced by determining whether internal noise among noise components of the user equipment is a dominant factor, based on capability information of the user equipment, and, when the internal noise is a dominant factor, performing a power adjustment operation that adjusts transmission power of at least one of signals or channels to be transmitted to the user equipment. An operation method of a wireless communication system includes receiving capability information including a determination parameter, determining whether internal noise among noise components of a user equipment is a dominant factor, based on the determination parameter, and, when the internal noise is determined to be a dominant factor, performing a power adjustment operation that adjusts transmission power.
