Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for adjusting uplink transmission power in communication technologies rely on terminal feedback, which may not accurately reflect the terminal's actual transmission capabilities, potentially leading to inefficient data transmission and excessive power consumption.
Innovation Solution
A method where a base station receives and analyzes sending capability information from a terminal's antenna modules to determine a target uplink transmission power, which is then notified to the terminal, allowing for power adjustments based on actual capabilities to enhance data transmission efficiency and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If uplink transmission power is adjusted based on terminal feedback of reference signal strength, then the base station can determine transmission power, but the transmission power may not accurately reflect the terminal's actual transmission capabilities leading to inefficient data transmission and excessive power consumption
Solution Approach 1:
The terminal reports antenna module sending capability information to the base station in advance before actual data transmission. This preliminary action allows the base station to have accurate knowledge of the terminal's transmission capabilities ahead of time, enabling more precise uplink transmission power determination that reflects actual terminal capabilities rather than just inferred values from reference signal feedback.
Solution Approach 2:
The system implements a feedback mechanism where the terminal reports its antenna module sending capability information (such as maximum sending capability, average sending capability, or minimum sending capability) to the base station. This feedback loop enables the base station to continuously update and adjust the uplink transmission power based on the terminal's actual capabilities, improving both measurement precision and transmission efficiency.
2Reliability
If uplink transmission power is increased to ensure data transmission quality, then transmission reliability improves, but power consumption increases
Solution Approach 1:
The base station adjusts the uplink transmission power parameter based on the reported antenna module sending capability information. By changing the power parameter according to actual terminal capabilities rather than using fixed or inferred values, the system achieves reliable data transmission while avoiding excessive power consumption. The power is set to match the terminal's actual sending capability, ensuring quality without waste.
Solution Approach 2:
The terminal autonomously measures and reports its own antenna module sending capability information to the base station. This self-service approach allows the terminal to provide accurate information about its own capabilities, enabling the base station to determine appropriate transmission power that matches actual terminal performance, thereby ensuring reliability while optimizing power consumption.
