Solution Overview
Problem
Existing wireless communication technologies, such as IEEE 802.11ad, are limited to single-user systems, preventing simultaneous transmission to multiple stations, and do not effectively utilize channel bonding for higher data rates in millimeter-wave bands.
Innovation Solution
Implementing multi-user (MU) mechanisms, including channel bonding and Multiple-Input-Multiple-Output (MIMO) schemes, to enable simultaneous transmission to multiple stations and increase channel bandwidth beyond the standard 2.16 GHz, using bonded channels for higher data rates in millimeter-wave networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If single-user system configuration is used, then system simplicity is maintained, but simultaneous transmission to multiple stations is prevented
Solution Approach 1:
The patent segments the channel bandwidth into multiple bonded channels (e.g., 2.16 GHz channels combined to form 4.32 GHz or 6.48 GHz channels). Each spatial stream can be assigned to different users on different channel segments, enabling multi-user transmission while maintaining manageable system complexity through modular channel organization
Solution Approach 2:
The patent introduces spatial dimensionality by implementing multiple spatial streams transmitted simultaneously across bonded channels. This transforms the system from single-user single-stream to multi-user multi-stream capability, allowing simultaneous service to multiple stations through spatial multiplexing
2Productivity
If channel bonding is implemented, then data rates are increased, but system complexity increases
Solution Approach 1:
The patent merges multiple 2.16 GHz channels into bonded channels (4.32 GHz or 6.48 GHz) to increase available bandwidth and data rates. By combining channels in a standardized manner defined in the specification, the system achieves higher productivity while controlling complexity through uniform bonding procedures
Solution Approach 2:
The patent changes the bandwidth parameter by allowing dynamic selection of bonded channel configurations (2x2.16 GHz, 3x2.16 GHz, etc.). This enables the system to adapt data rates to service requirements while managing complexity through parameter-based configuration rather than structural redesign
3Productivity
If single channel bandwidth is used, then device complexity is reduced, but data rates are limited
Solution Approach 1:
The patent implements dynamic channel bonding where the number and configuration of bonded channels can be adjusted based on service requirements. The system can dynamically select between 2.16 GHz, 4.32 GHz, or 6.48 GHz bonded channels, enabling adaptive data rates while managing complexity through dynamic reconfiguration rather than fixed architecture
