Engineering Contradiction Analysis
1Quantity of substance
If multiple wireless communication terminals transmit data simultaneously to a single base terminal using conventional methods, then data transmission bandwidth is limited, but communication efficiency deteriorates in high-density environments
Solution Approach 1:
The patent segments the data transmission process by dividing multiple terminals into different groups based on their data characteristics (e.g., delay-sensitive and delay-tolerant traffic). Each group is handled through distinct transmission paths or scheduling mechanisms, allowing simultaneous transmission without mutual interference. This segmentation enables the system to maintain high bandwidth utilization while preserving communication efficiency through differentiated handling of various data types.
2Quantity of substance
If conventional wireless communication methods are used in high-density environments, then device complexity increases, but data transmission bandwidth remains insufficient
Solution Approach 1:
The patent implements a base terminal that performs multiple functions: it acts as both a conventional access point and a coordinator for advanced multi-terminal transmission schemes. The base terminal universally handles different transmission modes (sequential and simultaneous), manages multiple terminal groups, and adapts its behavior based on channel conditions and data requirements. This multi-functionality allows the system to achieve high bandwidth without requiring each individual terminal to be overly complex.
