Solution Overview

Problem

Existing communication systems lack a solution for selecting a reasonable channel detection mechanism when employing a broadband spectrum with multiple sub-bands, particularly in unlicensed spectrum scenarios, leading to unfair occupation of channel resources with other wireless communication systems.

Innovation Solution

A method and apparatus for determining a channel detection mechanism that distinguishes between broadband and sub-band detection modes, allowing for the selection of appropriate channel detection mechanisms based on sub-bands, ensuring fair resource allocation by employing different determination methods for each mode.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a broadband spectrum including multiple sub-bands is employed for transmission, then the transmission capacity is improved, but it becomes difficult to select a reasonable channel detection mechanism

Engineering Contradiction:
Improvetransmission capacityVSAvoidchannel detection mechanism selection
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The broadband spectrum is divided into multiple sub-bands, and different channel detection mechanisms can be applied to different sub-bands. This segmentation allows the system to handle each sub-band independently with appropriate detection mechanisms, resolving the difficulty of selecting a single mechanism for the entire broadband spectrum while maintaining high transmission capacity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic selection of channel detection mechanisms based on the detection mode (broadband detection mode or sub-band detection mode). The system can adaptively switch between different detection mechanisms for different sub-bands according to channel conditions and requirements, providing versatility while supporting broadband transmission.

Inventive Principle:

2Device complexity

If a single channel detection mechanism is applied to the entire broadband spectrum, then the system complexity is reduced, but fair occupation of channel resources with other wireless communication systems cannot be achieved

Engineering Contradiction:

Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The broadband spectrum is segmented into multiple sub-bands, each of which can be detected independently. This allows different channel detection mechanisms to be applied to different sub-bands based on local channel conditions, achieving fair resource occupation with other systems while maintaining manageable complexity through modular sub-band processing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different channel detection mechanisms are applied to different sub-bands according to their specific channel conditions and requirements. This local optimization ensures that each sub-band is detected with the most appropriate mechanism, achieving fair resource occupation while the overall system complexity is controlled through standardized sub-band processing procedures.
