Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications, data transmitted from upper layers experiences increased delay due to interference and longer signal processing times, making it difficult to transmit data with low latency, especially in scenarios like online gaming and mechanical remote control, where timely data transmission is crucial.
Innovation Solution
A wireless communication device that includes a transmission control unit to transmit first data from an upper layer along with information regarding the timing of transmission of second data generated in another device, allowing for coordinated and timely data transfer, thereby reducing delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If data is transmitted using random access in MAC layer, then transmission opportunity can be acquired, but delay increases due to interference and uniform handling of all data
Solution Approach 1:
The patent segments data into two categories: first data (requiring low delay transmission) and second data (generated based on receiving first data). This segmentation allows the MAC layer to apply different transmission strategies to different data types, enabling discriminated handling that reduces delay for time-critical data while maintaining standard procedures for other data.
Solution Approach 2:
The patent transmits information regarding the timing of transmission of second data along with first data in advance. This preliminary action allows the receiving device to prepare for second data transmission without waiting for random access opportunities, thereby reducing overall delay while maintaining compatibility with standard MAC layer operations.
2Loss of time
If signal processing is performed in upper layer, then data can be transmitted with low delay, but signal processing time becomes longer compared to MAC layer
Solution Approach 1:
The patent introduces timing information as an intermediary element that bridges the upper layer and MAC layer. This timing information allows the MAC layer to coordinate transmission without requiring complete upper layer processing, effectively reducing the bottleneck caused by lengthy upper layer signal processing while maintaining data integrity and timing requirements.
