Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G communication systems, particularly terminals using higher frequency bands like mmWave, experience increased power consumption, necessitating a method to reduce power usage effectively.
Innovation Solution
A method involving a terminal and base station communication process where the terminal identifies its state and transmits power-related parameters to the base station, allowing for reconfiguration of power settings to optimize power consumption based on the terminal's state, including associating different states with specific bandwidth parts, power profiles, carrier numbers, and antenna operations.

Engineering Contradiction Analysis
1Productivity
If 5G communication systems use higher frequency bands (mmWave) and wider bandwidth, then data transmission capacity and speed are improved, but terminal power consumption increases
Solution Approach 1:
The patent applies dynamics by making the terminal's operational parameters adjustable and adaptive. The base station configures multiple power-related parameters (bandwidth parts, power profiles, carrier numbers, antenna operations) that can be dynamically changed based on terminal state, allowing the system to optimize between performance and power consumption in real-time
Solution Approach 2:
The patent directly applies parameter changes by modifying physical communication parameters (bandwidth, power profile, carrier aggregation, antenna operations) based on terminal state. The base station receives terminal state information and reconfigures these parameters to achieve optimal power efficiency while maintaining required data transmission capacity
2Speed
If the terminal operates in high-performance mode with wider bandwidth and higher frequency, then communication speed is improved, but usage time is reduced
Solution Approach 1:
The system dynamically adjusts communication parameters based on terminal state, allowing the terminal to switch between high-performance mode (faster communication) and power-saving mode (longer usage time) as needed, rather than operating in a fixed high-performance state
Solution Approach 2:
The terminal periodically reports its state to the base station, which then periodically reconfigures power-related parameters. This periodic feedback and reconfiguration allows the system to adapt to changing conditions while managing power consumption over time

AI summary
The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate compared to a 4G communication system such as an LTE. According to an embodiment of the present invention, a method performed by a terminal in a wireless communication system comprises the steps of: identifying, by a first processor of the terminal, a state of the terminal; transmitting the state of the terminal to a second processor of the terminal; identifying an electric power-related parameter associated with the state of the terminal; and transmitting, to a base station, a terminal message including the electric power-related parameter.
