Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional wireless communication systems transmit data sequentially to multiple terminals, then channel access control is simple, but bandwidth utilization is inefficient and data communication efficiency is low
Solution Approach 1:
The patent merges multiple sequential data transmission operations into a single simultaneous transmission operation. The base terminal transmits data to multiple terminals at the same time using multiple RF chains, combining what would traditionally be multiple separate transmission cycles into one unified operation, thereby improving bandwidth utilization and data communication efficiency
Solution Approach 2:
The patent introduces a new dimension of simultaneous multi-terminal transmission by employing multiple RF chains. Instead of transmitting to terminals sequentially in time, the system transmits to multiple terminals concurrently in the frequency domain through parallel RF chains, adding a dimensional transformation that resolves the efficiency-complexity contradiction
2Productivity
If multiple terminals transmit data simultaneously to a base terminal, then bandwidth utilization increases, but processing burden on terminals increases
Solution Approach 1:
The patent segments the transmission function by assigning specific RF chains to specific terminals. Each terminal is assigned a dedicated RF chain for receiving data, which divides the processing task and allows terminals to operate independently without interfering with each other's data reception, thereby managing processing burden while maintaining high bandwidth utilization
Solution Approach 2:
The base terminal acts as an intermediary that coordinates and manages the simultaneous transmissions. It assigns RF chains to terminals and manages the transmission process, shielding individual terminals from the complexity of handling multiple simultaneous transmissions by centralizing the coordination function
3Productivity
If a terminal uses multiple RF-chains for simultaneous transmission, then data communication efficiency improves, but device complexity increases
Solution Approach 1:
The patent implements multi-functionality where each RF chain can be dynamically assigned to different terminals based on transmission needs. The same RF chain infrastructure serves multiple terminals and multiple transmission functions, making the complex hardware resource flexible and adaptable, thereby justifying the structural complexity through enhanced functional capability
