Solution Overview

Problem

Current wireless communication systems face challenges in efficiently managing and configuring sidelink communication resources, particularly in vehicle-to-everything (V2X) scenarios, where existing methods often rely on centralized resource allocation and lack efficient power management.

Innovation Solution

The implementation of a method and system that allows user equipment (UE) to select and manage periodic communication resource sets (ComReSets) from a resource pool, enabling autonomous sidelink connection establishment and communication without relying on base station scheduling, using a resource pool configuration that includes multiple periodic ComReSets with varying time durations and periodicities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If centralized resource allocation by base station is used, then resource management control is improved, but system complexity and power consumption increase

Engineering Contradiction:

Improveresource management controlVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The resource pool is divided into multiple periodic communication resource sets (ComReSets) with different periods, each suitable for different traffic types. This segmentation allows UEs to select appropriate resource sets without requiring centralized scheduling for all resources, reducing system complexity while maintaining reliable resource management.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

UEs autonomously select and manage their own periodic ComReSets from the configured resource pools based on their traffic requirements. This self-service mechanism eliminates the need for continuous base station scheduling decisions, reducing system complexity and power consumption while maintaining reliable resource allocation.

Inventive Principle:

Principle #25Self-service

2Reliability

If centralized resource allocation by base station is used, then resource management control is improved, but power consumption increases

Engineering Contradiction:

Improveresource management controlVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

UEs independently select periodic ComReSets from pre-configured resource pools based on their own traffic patterns and requirements. This autonomous resource selection eliminates the need for continuous signaling with the base station, significantly reducing power consumption while maintaining reliable resource management control.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The base station performs preliminary configuration of periodic ComReSets in advance, providing a structured resource pool. UEs then autonomously select from these pre-configured options, eliminating the need for continuous centralized scheduling decisions and reducing ongoing power consumption.

Inventive Principle:

Principle #10Preliminary action

3Use of energy by moving object

If autonomous resource selection by UE is used, then power consumption is reduced, but resource allocation efficiency may worsen

Engineering Contradiction:

Improvepower consumptionVSAvoidresource allocation efficiency

Core Design Contradiction:

Use of energy by moving objectVSProductivity

Solution Approach 1:

The resource pool is segmented into multiple periodic ComReSets with different periods (e.g., short period for periodic traffic, long period for bursty traffic). This segmentation enables UEs to efficiently match resources to their specific traffic patterns without requiring complex centralized optimization, maintaining high resource allocation efficiency while reducing power consumption.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different periodic ComReSets are configured with varying parameters (period lengths, resource quantities) to match different traffic characteristics. UEs select ComReSets based on their traffic requirements, enabling efficient resource allocation through parameter matching rather than complex centralized scheduling.

Inventive Principle:

Principle #35Parameter changes

4Adaptability or versatility

If multiple periodic ComReSets with varying periods are configured, then adaptability to different traffic types is improved, but device complexity increases

Engineering Contradiction:

Improvetraffic type adaptabilityVSAvoidUE device complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The resource pool is divided into multiple periodic ComReSets, each optimized for specific traffic types (e.g., short period for periodic traffic, long period for bursty traffic). This segmentation provides high adaptability while keeping UE complexity low, as devices simply select from pre-configured options rather than dynamically optimizing resource allocation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent uses simple, standardized ComReSet configurations that can be easily selected and discarded. UEs choose from a limited set of pre-defined periodic ComReSets rather than performing complex real-time optimization, reducing device complexity while maintaining adaptability to different traffic patterns.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
