Solution Overview

Problem

Existing resource allocation mechanisms for Device-to-Device (D2D) and Vehicle-to-Everything (V2X) communications are inefficient in handling dynamic congestion scenarios, leading to higher latency, increased power consumption, and system-wide performance degradation due to rigid zone boundaries that cannot be dynamically adjusted to account for changing congestion levels.

Innovation Solution

Devices are configured to dynamically select resources from adjacent zones based on allowed measurement inaccuracies in Reference Signal Received Power (RSRP) or location, allowing them to exploit uncertainty in zone boundaries to reduce contention and improve resource utilization without modifying standard zone configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If devices use rigid zone boundaries for resource allocation, then resource allocation is simple and standardized, but resource utilization efficiency deteriorates under dynamic congestion scenarios

Engineering Contradiction:

Improveresource allocation simplicityVSAvoidresource utilization efficiency

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The patent applies dynamics by allowing devices to dynamically select resources from adjacent zones based on real-time congestion conditions. Instead of being fixed to a single zone's resources, devices can flexibly expand their resource selection to neighboring zones when congestion is detected, making the resource allocation system adaptive to changing traffic conditions while maintaining standard zone configurations.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of resource selection scope by allowing devices to adjust which zones' resources they can access based on congestion levels. When a zone is congested, the effective resource pool parameter expands to include adjacent zones, thereby improving resource utilization without modifying the underlying zone boundary definitions or standard configurations.

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If devices are confined to their assigned zone's resources, then zone management is straightforward, but latency increases due to resource contention

Engineering Contradiction:

Improvezone management complexityVSAvoidtransmission latency

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The patent reduces transmission latency by dynamically allowing devices to access resources from adjacent zones when their assigned zone is congested. This dynamic resource access mechanism prevents devices from being stuck waiting for resources in high-contention zones, thereby reducing idle time and overall transmission latency without complicating the fundamental zone management structure.

Inventive Principle:

Principle #15Dynamics

3Productivity

If devices monitor and adapt to congestion dynamically, then resource utilization improves, but power consumption increases

Engineering Contradiction:

Improveresource utilization efficiencyVSAvoiddevice power consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements partial monitoring where devices monitor congestion conditions but only actively adapt their resource selection when necessary (i.e., when congestion is detected). This partial action approach allows devices to maintain low power consumption during normal conditions while still achieving improved resource utilization when congestion occurs, avoiding continuous active monitoring and adaptation.

Inventive Principle:

Principle #16Partial or excessive action

4Stability of the object's composition

If zone boundaries are strictly enforced, then resource allocation is predictable and standardized, but system performance degrades under varying congestion conditions

Engineering Contradiction:

Improvezone boundary stabilityVSAvoidsystem performance

Core Design Contradiction:

Stability of the object's compositionVSProductivity

Solution Approach 1:

The patent maintains stable zone boundary definitions (standardized segmentation) while allowing devices to segment their resource selection behavior - sticking to their assigned zone under normal conditions but expanding to adjacent zones when congestion is detected. This segmented approach preserves the stability and predictability of zone structures while enabling performance adaptation to varying congestion conditions.

Inventive Principle:

Principle #1Segmentation
