Solution Overview

Problem

Current wireless communication systems face limitations in achieving full duplex communication due to multiplexing restriction parameters that restrict simultaneous transmission and reception, leading to reduced latency and efficiency in spectrum usage.

Innovation Solution

A method and apparatus that identify and ignore these multiplexing restriction parameters, enabling wireless communication devices to operate in full duplex mode by relaxing adherence to them, allowing simultaneous transmission and reception.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiplexing restriction parameters are enforced, then communication reliability is maintained, but full duplex communication capability is lost

Engineering Contradiction:
Improvefull duplex communication capabilityVSAvoidcommunication reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent changes the state of multiplexing restriction parameters from enforced to ignored/relaxed, enabling full duplex communication mode. By modifying the parameter state rather than changing the fundamental communication architecture, the system achieves simultaneous transmission and reception capabilities while maintaining reliability through alternative constraint mechanisms.

Inventive Principle:
Principle #35Parameter changes

2Loss of time

If multiplexing restriction parameters are enforced, then communication stability is ensured, but latency increases

Engineering Contradiction:
Improvecommunication latencyVSAvoidcommunication stability
Core Design Contradiction:
Loss of timeVSStability of the object's composition

Solution Approach 1:

The patent introduces dynamic parameter management where multiplexing restriction parameters can be selectively ignored based on communication mode requirements. This dynamic approach allows the system to switch between restricted and unrestricted parameter enforcement, enabling low-latency full duplex communication when needed while maintaining stability through controlled parameter relaxation.

Inventive Principle:
Principle #15Dynamics

3Productivity

If multiplexing restriction parameters are enforced, then resource allocation is controlled, but spectrum usage efficiency decreases

Engineering Contradiction:
Improvespectrum usage efficiencyVSAvoidparameter management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts and ignores specific multiplexing restriction parameters that hinder full duplex operation. By selectively removing these restrictive parameters from active enforcement, the system gains improved spectrum usage efficiency and productivity while managing complexity through targeted parameter elimination rather than complete parameter management.

Inventive Principle:
Principle #2Taking out (Extraction)
