Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current device-to-device communication processes in local area networks face issues with low data transmission speed and long transmission delays, especially in poor communication environments with strong interference, weak signals, insufficient resources, or high loads.
Innovation Solution
A terminal device equipped with both Wi-Fi and D2D (device-to-device) chips establishes multiple communication links using Wi-Fi and D2D sidelink protocols to transmit data, enabling multi-link collaborative transmission, which improves data transmission stability and rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single Wi-Fi link is used for device-to-device communication, then the communication setup is simple, but the data transmission speed is low and transmission delay is long in poor communication environments
Solution Approach 1:
The patent segments the communication task by establishing multiple independent communication links (first communication link and second communication link) between terminal devices. Each link can transmit data independently, allowing parallel data flow that increases overall transmission speed and reduces delay, directly resolving the contradiction between transmission speed and system complexity
Solution Approach 2:
The patent merges Wi-Fi technology and D2D sidelink technology into a unified multi-link communication system. By combining these two different communication technologies, the system leverages the strengths of both to achieve higher data transmission speeds and reduced latency while maintaining manageable complexity through standardized protocols
2Reliability
If multiple communication links are established for multi-link collaborative transmission, then data transmission speed and stability improve, but the device complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where terminal devices monitor the status of each communication link and dynamically adjust data routing. When link degradation or failure is detected, the system automatically switches to alternative links, ensuring transmission reliability while managing complexity through automated link status monitoring and adaptive routing decisions

AI summary
The present disclosure relates to terminal devices, multi-link communication methods, and chips. In one example method, when a terminal device supports Wi-Fi and D2D (for example, V2X) communication, the terminal device may communicate with another terminal device in a multi-link collaborative transmission manner such as a Wi-Fi link and a D2D link to implement multi-link accelerated transmission in a local area network.
