Autonomous Uplink Power Control for High-Frequency Resource Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 6G wireless communication systems using high frequencies, determining transmission parameters for autonomously selected resources is necessary to optimize network performance due to characteristics such as wide bandwidth, high radio wave straightness, and low frequency selectivity, which differ from conventional cell design or scheduling techniques.
Innovation Solution
A communication device with a receiving unit, control unit, and transmitting unit that determines transmission power based on received information to autonomously select resources for signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional base station scheduling techniques are used, then resource allocation is controlled, but resource collisions and interference occur frequently at high frequencies
Solution Approach 1:
The terminal autonomously selects uplink transmission resources without base station scheduling by monitoring downlink assignments and determining autonomous resources where no downlink transmission is scheduled, thereby serving itself to avoid resource collisions and interference at high frequencies
Solution Approach 2:
The system dynamically adapts resource allocation by allowing terminals to autonomously select resources based on real-time downlink scheduling information, creating a flexible resource management approach that responds to changing channel conditions and traffic patterns
2Productivity
If high frequency bands are used, then communication speed and capacity increase, but transmission parameter determination becomes more difficult
Solution Approach 1:
The patent extracts the transmission parameter determination function from the base station and relocates it to the terminal, allowing the terminal to independently determine uplink transmission parameters based on received downlink information, thereby simplifying the overall system complexity while maintaining high-speed communication capabilities
Solution Approach 2:
The system changes the determination parameters from base-station-controlled scheduling to terminal-autonomous selection based on downlink assignment patterns, adapting the parameter determination mechanism to suit high-frequency characteristics where rapid channel variations make conventional scheduling less effective
