Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a first beam spatial setting is used for inter-device transmission, then communication coverage is provided, but interference with other beams increases
Solution Approach 1:
The patent segments the spatial communication space into multiple non-overlapping beams. Each beam is assigned a unique spatial setting (SDA/SDR parameters) that defines its specific direction and coverage area. This segmentation ensures that each beam operates independently without interfering with others, resolving the contradiction between providing communication coverage and avoiding interference.
Solution Approach 2:
The patent applies local quality by configuring each beam with customized spatial domain parameters (SDA for transmission, SDR for reception) tailored to its specific directional requirements. Each beam's spatial setting is optimized for its local coverage area, allowing the system to provide reliable communication in each direction while maintaining overall low interference across the entire spatial spectrum.
2Productivity
If multiple beams are used for simultaneous transmissions, then communication capacity increases, but beam management complexity increases
Solution Approach 1:
The patent implements dynamic beam management where the network device can dynamically adjust and reconfigure spatial domain parameters for multiple beams based on real-time communication conditions. The system dynamically allocates spatial settings to different beams and can modify these settings as devices move or communication requirements change, enabling high communication capacity while maintaining manageable complexity through adaptive control.
Solution Approach 2:
The patent employs feedback mechanisms where receiving devices report spatial domain parameter information back to transmitting devices and network controllers. This feedback enables automatic adjustment of beam configurations, spatial filtering parameters, and resource allocation, allowing the system to manage multiple beams efficiently without manual intervention, thus increasing capacity while keeping management complexity可控.
3Reliability
If spatial filtering is applied to reduce interference, then signal quality improves, but processing requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring spatial domain parameters (SDA/SDR) and spatial filtering settings before actual data transmission begins. The network device pre-calculates and assigns optimal spatial filters to each beam based on predicted communication patterns and device locations. This preprocessing reduces real-time computational requirements during active transmission, improving signal quality while limiting processing power consumption to acceptable levels.
