Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In radio communications networks, especially in scenarios like 3GPP LTE/NR V2X, there is a challenge in managing resource conflicts between user equipment (UEs) within and out of network coverage, leading to potential resource conflicts that can cause interference and inefficiencies in resource allocation.

Innovation Solution

An apparatus and method that determine and transmit resource conflict indicators to identify potentially conflicting radio resources, allowing for adaptive resource management and scheduling to avoid conflicts, thereby optimizing resource usage and reducing energy consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If distributed scheduling mechanisms are used for resource allocation, then resource conflicts between UEs increase, but network coverage flexibility improves

Engineering Contradiction:

Improvenetwork coverage flexibilityVSAvoidresource conflict risk

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements sensing mechanisms where UEs monitor radio signals and detect resource conflicts, then feed back this information through resource conflict indicators to enable adaptive resource allocation decisions

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent introduces resource conflict indicators as intermediary signals that mediate between distributed UEs, allowing them to coordinate resource usage without centralized control while reducing direct conflicts

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If sensing operations are performed by all UEs to detect resource conflicts, then resource allocation reliability improves, but network energy consumption increases

Engineering Contradiction:

Improveresource allocation accuracyVSAvoidnetwork energy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent enables UEs to serve multiple functions: they act as both sensors detecting resource conflicts and as transmitters of resource conflict indicators, allowing information sharing without requiring every UE to perform complete sensing operations

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent allows UEs to benefit from resource conflict information generated by other UEs' sensing operations, reducing the need for each UE to independently perform energy-intensive sensing while maintaining reliable resource allocation

Inventive Principle:

Principle #25Self-service

3Reliability

If resource conflict indicators are transmitted frequently to maintain up-to-date information, then resource allocation reliability improves, but communication overhead increases

Engineering Contradiction:

Improveresource conflict information freshnessVSAvoidcommunication overhead

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent implements periodic transmission of resource conflict indicators at configured intervals, maintaining relatively current information while avoiding continuous transmission that would generate excessive overhead

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent employs validity indicators to track the age and reliability of resource conflict information, allowing UEs to discard outdated indicators and request updates only when necessary, reducing unnecessary communication

Inventive Principle:

Principle #34Discarding and recovering

AI summary

An apparatus (UE1, UE2) comprising at least one processor, at least one memory including computer program code, and at least one communication module. The at least one memory and computer program code are configured, with the at least one processor, and the at least one communication module, to cause the apparatus (UE1, UE2) to receive (100, 206) a plurality of radio signal (s0, s2) or at least one resource conflict indicator (RCI). The at least one resource conflict indicator (RCI) indicates at least one radio resource (rr1) that has a potential risk of a resource conflict.
