1Ease of operation
If end users manually adjust transmission rate, then transmission rate can be changed, but users lack knowledge to choose suitable rate and must continuously adjust it
Solution Approach 1:
The system performs self-adjustment of transmission rate by automatically detecting channel conditions (signal strength, packet error rate) and selecting appropriate rates without user intervention. The base station continuously monitors communication quality and dynamically adjusts rates based on predetermined thresholds, making the system self-regulating.
Solution Approach 2:
The system establishes feedback loops where transmission performance metrics (packet error rate, signal strength) are continuously measured and fed back to the base station. This feedback enables automatic rate adjustment decisions, creating a closed-loop control system that adapts to changing channel conditions without user input.
2Productivity
If high transmission rate is used, then throughput increases in good channel conditions, but performance deteriorates when channel fading is significant
Solution Approach 1:
The transmission rate is made dynamic rather than fixed, allowing the system to adapt to varying channel conditions. The base station continuously monitors communication quality metrics and adjusts transmission rates in real-time, transitioning between different rate levels based on current channel state to maintain both high throughput and reliability.
Solution Approach 2:
The system changes the transmission rate parameter based on detected channel conditions. When signal strength or packet error rate indicates poor channel quality, the system automatically transitions to lower transmission rates, and vice versa, optimizing the balance between throughput and communication reliability.
3Productivity
If automatic rate adjustment is implemented, then system throughput improves, but system complexity increases
Solution Approach 1:
The base station acts as an intermediary that centralizes the rate adjustment function. Rather than requiring complex user-side decision-making or continuous user intervention, the base station serves as the intelligent mediator that monitors channel conditions and controls rate changes, simplifying the overall system architecture while maintaining automatic adaptation.

AI summary
The present invention provides a method for dynamically adjusting the transmission rate of a wireless communication system. The method comprises the steps of: setting an initial transmission rate; counting the number of successful or unsuccessful transmission; comparing the number with a predetermined threshold and obtaining a comparing result; and adjusting the transmission rate according to the comparing result. The present invention also provides a method that uses the strength of received signals to determine if the transmission rate needs adjusting.
