Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems in the millimeter-wave band face challenges in achieving high-speed data transmission and efficient communication due to limitations in phased antenna arrays and Multi-In-Multi-Out (MIMO) configurations, particularly in directional bands above 45 GHz, where existing technologies struggle to maximize data rates and adapt to varying Line of Sight (LOS) and Non-Line of Sight (NLOS) environments.
Innovation Solution
The implementation of Single-User (SU) MIMO configurations using phased antenna arrays with specific polarization types and configurations, such as single or dual polarization, and varying numbers of Phase Antenna Arrays (PAAs) to optimize data streams and RF chains, enabling efficient beamforming and communication over directional wireless communication bands, as defined in the SU-MIMO configurations #1 to #5, which allow for up to 4 data streams and adapt to different environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If phased antenna arrays are used in millimeter-wave band, then high-speed data access is provided, but limitations in MIMO configurations reduce data rates and adaptability
Solution Approach 1:
The patent implements dynamic MIMO configurations that can adapt between different numbers of transmit and receive antennas based on environmental conditions. The system dynamically selects from multiple SU-MIMO configurations (#1-#5) with varying antenna arrangements to optimize performance in LOS and NLOS scenarios, making the system flexible rather than fixed.
Solution Approach 2:
The patent changes key parameters including polarization types (single or dual), number of PAAs (one or two), number of RF chains (one or two per PAA), and number of data streams (one, two, three, or four) to achieve different data rates and adapt to varying environmental conditions, thereby resolving the contradiction between fixed architecture and adaptability.
2Productivity
If multiple PAAs with dual polarization are used, then more data streams can be transmitted, but device complexity and power consumption increase
Solution Approach 1:
The patent segments the MIMO system into distinct configurable modules: multiple PAA units, multiple RF chains, and multiple polarization options. Each module can be independently configured and activated based on required data rate, allowing the system to scale complexity only when needed rather than requiring maximum capability in all cases.
Solution Approach 2:
The patent designs a universal PAA architecture that can operate in multiple modes (single/dual polarization, one/two PAAs, different RF chain configurations) to support various data stream requirements. This multi-functional design allows the same hardware platform to achieve different productivity levels without requiring separate specialized systems for each configuration.
3Productivity
If SU-MIMO configurations with up to 4 data streams are implemented, then high-speed applications are supported, but system complexity increases
Solution Approach 1:
The patent implements dynamic selection among five predefined SU-MIMO configurations (#1-#5) with varying numbers of data streams (1-4). The system can dynamically switch between these configurations based on application requirements, environmental conditions, and channel quality, enabling high-speed operation when needed while simplifying operation for standard applications.
