UE Resource Allocation in Wireless Communication Systems

Solution Overview

Problem

Current wireless communication systems face challenges in efficiently allocating resources for signal transmission, particularly in scenarios like V2X communication, where high costs and complexity arise from the need for extensive infrastructure and efficient resource management.

Innovation Solution

A method for resource allocation in wireless communication systems, allowing user equipment (UE) to select or be informed of available resource units from a resource pool for direct signal transmission, enabling efficient communication without relying solely on network infrastructure, and supporting scenarios like V2X and D2D communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If network infrastructure is used for resource allocation in V2X communication, then communication reliability is improved, but infrastructure cost and system complexity increase

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidinfrastructure cost

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent enables user equipment to autonomously select and allocate communication resources from a pre-configured resource pool without requiring continuous network infrastructure intervention. The UE independently performs resource selection based on sensing results and transmission requirements, eliminating the need for complex centralized resource allocation infrastructure while maintaining communication reliability through distributed autonomous decision-making

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent extracts the resource allocation function from the network infrastructure and transfers it to the user equipment. By removing the dependency on network-based resource allocation mechanisms, the system reduces infrastructure complexity and cost while enabling direct UE-to-UE resource management for V2X communication

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If centralized resource allocation is used, then resource management control is improved, but resource utilization efficiency decreases

Engineering Contradiction:

Improveresource management controlVSAvoidresource utilization efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent inverts the traditional centralized resource allocation approach by enabling distributed autonomous resource selection at the UE level. Instead of the network centrally assigning resources, each UE independently selects resources from the available pool based on local sensing and transmission needs, thereby improving resource utilization efficiency while maintaining adequate control through pre-configured resource pools and sensing mechanisms

Inventive Principle:

Principle #13The other way round (Inversion)

3Area of stationary object

If extensive infrastructure is deployed for V2X communication, then communication coverage is improved, but system cost and complexity increase

Engineering Contradiction:

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent enables user equipment to autonomously select and allocate communication resources from a pre-configured resource pool without requiring continuous network infrastructure intervention. The UE independently performs resource selection based on sensing results and transmission requirements, eliminating the need for complex centralized resource allocation infrastructure while maintaining communication reliability through distributed autonomous decision-making

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent creates a universal resource pool that can be used by multiple UEs for various V2X communication scenarios. This shared resource pool approach allows the system to provide broad communication coverage without requiring dedicated infrastructure for each UE or scenario, reducing overall system cost and complexity while maintaining versatile communication capabilities

Inventive Principle:

Principle #6Universality (Multi-functionality)
