Innovation Solution

A method and apparatus for identifying radio resources using OAM mode domain information, where the OAM mode domain identifier is related to transmission parameters of vortex electromagnetic waves and serves as an OAM logical mode, allowing for universal identification regardless of physical antenna arrays and OAM physical modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If radio resources are identified using OAM physical modes directly, then the identification is specific to physical implementations, but the complexity increases and universality decreases due to dependency on physical antenna arrays

Engineering Contradiction:
ImproveUniversality of radio resource identificationVSAvoidComplexity of identification system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an OAM mode domain identifier as an intermediary layer between the physical OAM modes and the radio resource identification system. This identifier abstracts the physical implementation details, allowing radio resources to be identified without direct dependency on specific antenna array configurations. The intermediary layer enables universal identification across different physical implementations while maintaining the benefits of OAM mode diversity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The OAM mode domain identifier is designed to be universal and independent of specific physical antenna array implementations. It can represent multiple OAM physical modes and work across different frequency bands and transmission scenarios. This universal identifier allows the same identification mechanism to function in various contexts without requiring implementation-specific customization, thereby reducing system complexity while maintaining adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If multiple OAM physical modes are used to increase channel capacity, then spectral efficiency improves, but the difficulty of managing and identifying resources increases

Engineering Contradiction:
ImproveChannel capacityVSAvoidDifficulty of resource identification
Core Design Contradiction:
ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent segments the complex OAM mode management into distinct layers: physical OAM modes at the transmission level and abstract OAM mode domain identifiers at the resource identification level. This segmentation allows multiple OAM physical modes to be used simultaneously to increase channel capacity, while the segmented identifier system simplifies resource management by providing a unified, simplified interface for identifying and managing the diverse modes without requiring complex detection and measurement of each physical mode's specifics.

Inventive Principle:
Principle #1Segmentation
