Wireless Transmission Rate Control for Control Data Error Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems employing adaptive modulation schemes face increased error rates in control data, leading to potential failure in retransmission processes due to errors in control data, which disrupt communication control processes.
Innovation Solution
A transmitting apparatus that includes a transmission data acquisition unit, a judging unit to identify control data, and a transmission rate control unit, which lowers the transmission rate of control data to minimize errors by controlling the modulation scheme based on the presence of control data within the transmission data.

Engineering Contradiction Analysis
1Productivity
If a high communication rate is used to improve transmission efficiency, then productivity increases, but the error occurrence rate in control data increases
Solution Approach 1:
The patent applies different transmission rates to different types of data: control data is transmitted at a lower, more reliable rate while communication data can use higher rates. This local differentiation of transmission quality resolves the contradiction by protecting critical control data from errors while maintaining overall system productivity through selective rate adjustment rather than uniform rate reduction
Solution Approach 2:
The system dynamically changes the transmission rate parameter based on data type identification. When control data is detected, the transmission rate is reduced to a predetermined lower value, thereby reducing the error occurrence rate for control data while allowing communication data to maintain higher rates for improved productivity
2Reliability
If the transmission rate is reduced to suppress errors in control data, then reliability improves, but the communication efficiency deteriorates
Solution Approach 1:
Instead of reducing the transmission rate for all data (which would harm overall communication efficiency), the patent selectively applies lower transmission rates only to control data while maintaining higher rates for communication data. This localized approach preserves reliability for critical control functions without sacrificing overall system productivity
Solution Approach 2:
The transmission rate parameter is dynamically adjusted based on the type of data being transmitted. Control data triggers a parameter change to a lower rate for error suppression, while communication data maintains a higher rate for efficiency, thereby resolving the contradiction between reliability and productivity

AI summary
A wireless communication apparatus (10) includes: a transmission data acquisition unit (21) that acquires transmission data; a control data judging unit (24) that judges whether or not the acquired transmission data is control data for causing an apparatus that receives the transmission data to perform a predetermined communication control process; and a transmission rate control unit (33) that controls a transmission rate of the transmission data according to a judgment result of the control data judging unit (24).
