Collaborative Equipment Set for Low Latency Wireless Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies face challenges in achieving low latency and high reliability, particularly in applications like factory automation and remote driving, where delays exceed microsecond levels and require multiple retransmissions, leading to inefficiencies and reliability issues.
Innovation Solution
The implementation of an electronic device with processing circuitry that forms a collaborative equipment set to jointly transmit and receive data, using a spatially-collaborative retransmission method where multiple equipment work together to forward and decode data packets, reducing latency and enhancing reliability through optimized channel usage and diverse communication paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of retransmissions is increased to meet reliability requirements, then communication reliability is improved, but transmission delay increases
Solution Approach 1:
The patent pre-establishes a collaborative equipment set that includes alternative transmission paths and relay nodes before communication failures occur. When a transmission failure is detected, the system can immediately switch to pre-configured relay nodes or alternative paths without needing to perform complex real-time route selection, thereby reducing the time penalty associated with retransmissions while maintaining high reliability
Solution Approach 2:
The patent introduces collaborative equipment (relay nodes) as intermediaries between the transmitter and receiver. These intermediaries can forward data packets, providing alternative transmission paths that bypass failed direct links. This mediator approach enables faster retransmission by using pre-established relay relationships rather than performing complete route rediscovery, thus improving reliability while minimizing delay
2Device complexity
If traditional single-path transmission is used, then system complexity is kept low, but communication reliability deteriorates in diverse environments
Solution Approach 1:
The patent segments the communication path into multiple independent transmission routes by establishing a collaborative equipment set with multiple relay nodes. Each segment (transmitter→relay→receiver) can operate independently, so if one path fails, others remain functional. This segmentation provides diversity without requiring complex dynamic routing logic, as the segmented paths are pre-configured
Solution Approach 2:
The patent merges multiple transmission paths by having collaborative equipment forward data packets through different routes simultaneously or alternatively. The receiver can combine information from multiple paths, improving reliability through diversity while the merging process follows pre-established rules that prevent excessive complexity in path management
