Solution Overview

Problem

Current wireless communication systems in the millimeter-wave band face challenges in efficiently transmitting data at high speeds and maintaining compatibility across different environments and channel conditions, particularly in optimizing Guard Interval (GI) lengths for various applications and channel bonding factors.

Innovation Solution

The implementation of a symbol block structure with multiple GI types (short, medium, and long) and channel bonding factors, utilizing Golay sequences, allows for adaptable GI lengths and data block sizes to optimize transmission efficiency and compatibility across different environments and channel conditions, enabling higher data transmission rates and improved compatibility with existing standards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed Guard Interval length is used in millimeter-wave wireless communication, then the system is simple to implement, but it cannot adapt to varying channel conditions and environments, reducing transmission efficiency

Engineering Contradiction:
Improveadaptability to channel conditionsVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic Guard Interval selection by allowing the system to switch between different GI lengths (short, medium, long) based on channel conditions and transmission requirements. This is achieved through configurable GI parameters that can be adjusted according to the specific millimeter-wave communication scenario, enabling the system to adapt to varying environments while maintaining manageable complexity through standardized selection criteria

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the Guard Interval parameter from a fixed value to a selectable set of values (different lengths and types). By introducing multiple GI parameter options (short GI, medium GI, long GI with different durations and structures), the system can optimize transmission performance for different channel conditions without requiring complete system redesign, thus improving adaptability while controlling complexity through parameterization

Inventive Principle:
Principle #35Parameter changes

2Reliability

If longer Guard Interval is used to handle multipath interference, then transmission reliability improves, but data transmission rate decreases due to increased overhead

Engineering Contradiction:
Improvetransmission reliabilityVSAvoiddata transmission rate
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent dynamically selects the appropriate Guard Interval length based on the actual channel conditions and transmission requirements. When multipath interference is severe, longer GIs are selected to maintain reliability; when channel conditions are good, shorter GIs are used to maximize data transmission rate. This dynamic adaptation resolves the contradiction by making the GI length conditional rather than fixed

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces multiple Guard Interval parameter configurations (different lengths and types) that can be selected based on transmission needs. By providing a range of GI parameter options rather than a single fixed value, the system can optimize the balance between reliability and transmission rate by selecting the appropriate parameter set for each specific communication scenario

Inventive Principle:
Principle #35Parameter changes

3Productivity

If multiple Guard Interval types are implemented for different applications, then transmission efficiency is optimized for various environments, but system complexity increases

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the Guard Interval into different types (short GI, medium GI, long GI) with distinct characteristics and use cases. Each GI type is optimized for specific transmission scenarios, allowing the system to select the most appropriate segment for each application. This segmentation improves transmission efficiency by matching GI characteristics to environmental requirements while managing complexity through clear categorization and selection criteria

Inventive Principle:
Principle #1Segmentation
