Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sidelink communication technologies face challenges in optimizing network operations, including resource management, mobility management, security, authentication, interoperability, routing, and relaying strategies, particularly in scenarios where traditional network infrastructure is limited or impractical.
Innovation Solution
A wireless communication device selects a relay device for sidelink communication based on various selection factors such as throughput, signal strength, bandwidth, and historical connection data, using a selection engine or artificial neural network to establish an optimal sidelink connection, which can be continuously re-evaluated for improved network performance.

Engineering Contradiction Analysis
1Area of stationary object
If traditional network infrastructure is deployed to provide network coverage, then network coverage area is improved, but deployment cost and complexity increase significantly in remote or underserved areas
Solution Approach 1:
The patent introduces relay devices as intermediary nodes that enable network coverage extension without requiring direct base station deployment in remote areas. These relay devices act as mediators between user equipment and the core network, allowing coverage expansion through device-to-device communication while avoiding the complexity of traditional infrastructure deployment in underserved areas.
Solution Approach 2:
The system enables self-organizing relay selection where user equipment autonomously discovers and selects optimal relay devices based on selection criteria such as signal strength, load, and compatibility. This self-service mechanism eliminates the need for complex manual configuration and deployment management, allowing the network to automatically adapt and optimize its coverage extension strategy.
2Reliability
If relay device selection is based on multiple selection factors including throughput and signal strength, then connection quality is improved, but selection process complexity increases
Solution Approach 1:
The patent implements preliminary relay discovery and evaluation where user equipment proactively identifies potential relay devices and pre-assesses them against multiple selection criteria before actual connection establishment. This preliminary action includes evaluating signal strength, throughput capability, and other factors in advance, allowing the system to make informed selection decisions without complex real-time computations during connection setup.
Solution Approach 2:
The system incorporates feedback mechanisms where relay devices report their current status, load, and capability information to user equipment. This feedback enables dynamic selection based on real-time network conditions, allowing the system to optimize connection quality by selecting relays that currently best meet the selection criteria while keeping the selection process manageable through structured information exchange.
