Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If directional beams are used to improve transmission speed and confidentiality in millimeter wave band, then transmission speed and security are improved, but communication area is limited and environments of use are restricted
Solution Approach 1:
The patent implements dynamic beam switching mechanisms where terminal stations can switch between different directional beams based on communication needs. The base station controls multiple terminal stations to use different directional beams, allowing the system to adapt to changing environments and maintain both high transmission speed and extended communication coverage.
Solution Approach 2:
The patent creates a multi-functional communication system that supports both direct communication between terminal stations and indirect communication through the base station. The system can dynamically select communication paths and beam configurations to serve multiple application scenarios, thereby improving versatility while maintaining high transmission speed.
2Productivity
If frame aggregation technology is used to improve MAC efficiency and transmission speed, then productivity is improved, but bit error rate increases and robustness decreases
Solution Approach 1:
The patent segments the aggregated frame structure into multiple smaller transmission units with individual error protection. By dividing the communication data into manageable segments and applying error correction codes to each segment, the system maintains high transmission efficiency while reducing the impact of bit errors on overall communication reliability.
Solution Approach 2:
The patent implements prior cushioning by adding error correction codes and redundancy information before frame aggregation. This preprocessing step creates a protective layer that cushions against bit errors, allowing the system to achieve high MAC efficiency through frame aggregation while maintaining robustness against transmission errors.
3Adaptability or versatility
If directional antennas are adjusted to cover multiple terminal stations, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent introduces the base station as an intermediary that manages and coordinates the directional antennas of multiple terminal stations. The base station receives location information and communication requirements, then controls the terminal stations' directional antennas to point toward appropriate targets. This intermediary approach enables multi-station coverage while keeping individual terminal station complexity low.
Solution Approach 2:
The patent implements self-service mechanisms where terminal stations autonomously adjust their directional beams based on location information and communication partner data provided by the base station. The terminal stations perform automatic beam alignment and directional adjustment without requiring complex centralized control, thereby improving coverage while reducing overall system complexity.

AI summary
The present invention provides a wireless communication system that performs a communication using directional beams formed in a plurality of directions including at least a first wireless terminal station (1) that transmits beam transmission direction identification information in all directions, in which the information can be transmitted, over a period designated from a wireless base station (0) and a second wireless terminal station (2) that performs reception operation for the transmission direction identification information, which is transmitted from the first wireless terminal station (1), in all reception directions over a period designated from the wireless base station (0), combines reception direction identification information and the transmission direction identification information at the reception of the transmission direction identification information to specify the combined reception direction identification information and the transmission direction identification information as directivity direction combination information, and transmits the directivity direction combination information to the wireless base station. The first wireless terminal station (1) and the second wireless terminal station (2) form directional beams in directions indicated by the directivity direction combination information to thereby perform a direct communication.
