Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current mobile communication systems fail to dynamically redistribute resources among transceivers based on their varying current requirements, leading to inefficiencies in resource allocation, especially in V2X networks.

Innovation Solution

A method for resource sharing between mobile transceivers, where a donor transceiver can offer unused resources and a taker transceiver can request them, using sidelink communication to exchange resource scheduling requests and grants, enabling dynamic resource redistribution and prioritization based on Quality of Service (QoS) requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If centralized or distributed resource allocation modes are used, then resource allocation can be performed, but the current requirements for resources of different mobile transceivers cannot be taken into account

Engineering Contradiction:

Improveadaptability to current resource requirementsVSAvoidresource utilization efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements dynamic resource allocation where transceivers can change their resource status between donor and taker roles based on real-time requirements. The system allows resources to be dynamically shared through signaling messages (SCI) that indicate donor status, enabling the network to adapt to varying resource demands of different transceivers at different times.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent employs feedback mechanisms where transceivers signal their resource status and requirements to the network. Through SCI messages containing donor indicators and resource status information, the system receives feedback about current resource conditions and adjusts allocations accordingly, creating a closed-loop control system that responds to actual network conditions.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If resources are allocated statically, then allocation simplicity is maintained, but resource redistribution based on varying requirements is not enabled

Engineering Contradiction:

Improveresource redistribution capabilityVSAvoidresource management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent enables transceivers to autonomously indicate their resource status and participate in resource sharing decisions through self-signaling mechanisms. Each transceiver can independently signal whether it is a donor or taker, and the resource allocation is determined through distributed signaling rather than centralized control, reducing the complexity of resource management while enabling dynamic redistribution.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent introduces signaling messages (SCI) as intermediaries that carry resource status information between transceivers and the network. These messages act as mediators that convey donor indicators, resource availability, and allocation decisions without requiring complex direct coordination between all transceivers, thereby managing complexity while enabling resource redistribution.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If resource sharing signaling is implemented, then dynamic resource allocation is enabled, but latency in resource allocation may increase

Engineering Contradiction:

Improveresource allocation efficiencyVSAvoidresource allocation latency

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent implements preliminary actions by having transceivers pre-signal their donor status and resource availability before actual resource sharing is needed. The SCI messages containing donor indicators are transmitted in advance, allowing the network to prepare resource allocations and reducing the time required for resource sharing when demands arise.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent maintains continuous resource allocation processes through ongoing signaling between transceivers and the network. Rather than periodic or event-triggered updates only, the system continuously monitors and signals resource status changes, ensuring that resource allocation information is always current and reducing latency when resource sharing is required.

Inventive Principle:

Principle #20Continuity of useful action
