Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-frequency millimeter-waves are used to increase data transfer rates, then bandwidth and data transfer rates are improved, but path loss increases
Solution Approach 1:
The patent changes the parameter of antenna operation frequency to millimeter-wave range (30-300 GHz) to achieve wider bandwidth and higher data transfer rates. This parameter change directly addresses the contradiction by operating in a frequency band that provides sufficient bandwidth while using beamforming to compensate for the inherent path loss at these frequencies.
Solution Approach 2:
The patent applies beamforming technology to create directional signal transmission and reception. By concentrating signal energy in specific directions rather than omnidirectional transmission, the system compensates for path loss at millimeter-wave frequencies. The base station and mobile device independently determine beam directions and adjust beamwidths to maintain communication quality despite the high path loss inherent in millimeter-wave propagation.
2Reliability
If beamforming is used to compensate path loss, then communication quality is improved, but system complexity increases
Solution Approach 1:
The patent implements autonomous beam management where the base station and mobile device independently determine optimal beam directions and configurations. Each device performs self-service by autonomously selecting beams and adjusting parameters without requiring complex centralized control, thereby reducing overall system complexity while maintaining communication quality.
Solution Approach 2:
The patent employs preliminary beam training and selection procedures where beams are pre-configured and evaluated before actual data transmission. This preliminary action allows the system to establish optimal beam configurations in advance, reducing the complexity of real-time beam management during active communication.
3Loss of energy
If antenna arrays with many elements are deployed to achieve high-gain beamforming, then path loss compensation is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements dynamic beamforming where antenna weights and beam directions are continuously adjusted based on channel conditions and feedback. This dynamic adaptation allows the system to achieve effective path loss compensation through intelligent signal processing rather than relying solely on increasing the number of antenna elements, thereby controlling device complexity.
Solution Approach 2:
The patent divides the beamforming functionality into separate modules: beam training, beam selection, and beam maintenance. This segmentation allows each module to be optimized independently and simplifies the overall system design. The base station and mobile device each handle specific segments of the beamforming process, reducing the complexity burden on any single component.

AI summary
Communication structure for communication with a mobile communication apparatus includes a signal conduction module having an array of antenna units; and a signal transceiving module including a signal transceiving unit, control unit, and power control unit. The control unit generates a driving signal to the power control unit, which generates a voltage to the signal transceiving unit; the signal transceiving unit generates a corresponding spectrum signal, transferred by the signal conduction module. The mobile communication apparatus receives the spectrum signal and transfers a first feedback signal. The first feedback signal, after being received by the signal conduction module, is transferred to the signal transceiving unit, which generates a second feedback signal to the control unit, the control unit identifies the second feedback signal and generates a control signal to the signal conduction module; the array of antenna units is controlled by the control signal correspondingly to enhance communication quality.
