Communication Device Dynamic ACK Transmission Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE communication systems, the Delayed TCP ACK method can cause delays in data transmission and reception due to the reduction in communication speed resulting from the increased number of ACKs transmitted, especially when the radio quality is unfavorable, leading to resource deficiencies and reduced throughput.
Innovation Solution
A communication device that dynamically switches between first and second transmission processing based on radio quality, where the first processing transmits a single ACK for a predetermined number of packets and the second processing transmits an ACK for every packet received, optimizing ACK transmission according to radio conditions to maintain communication speed and reduce resource deficiencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the Delayed TCP ACK method is used to reduce the number of transmitted ACKs, then communication resource usage is improved, but communication speed deteriorates
Solution Approach 1:
The patent implements dynamic switching between two transmission processing modes (first and second processing) based on radio quality conditions. The controller selects the first processing mode when radio quality is favorable to reduce ACK transmission frequency, and switches to the second processing mode when radio quality deteriorates to maintain communication speed, thereby dynamically optimizing the trade-off between resource usage and communication speed
Solution Approach 2:
The patent changes the parameter of ACK transmission frequency based on radio quality conditions. By adjusting the transmission processing mode according to radio quality measurements, the system modifies the effective ACK transmission rate to optimize performance under varying network conditions
2Quantity of substance
If the number of transmitted ACKs is reduced by Delayed TCP ACK method, then resource usage is improved, but data transmission delay increases
Solution Approach 1:
The system dynamically adjusts ACK transmission behavior by switching between first and second transmission processing modes based on real-time radio quality assessment. When radio quality is good, the first mode reduces ACK frequency to save resources; when radio quality worsens, the second mode increases ACK frequency to reduce transmission delays, thereby dynamically balancing resource efficiency and timing performance
3Speed
If ACK transmission is increased to maintain communication speed, then communication speed is improved, but communication resource usage deteriorates
Solution Approach 1:
The patent changes the transmission processing parameter based on radio quality conditions. By selecting between first and second processing modes according to measured radio quality, the system adjusts the effective ACK transmission rate to optimize the balance between maintaining communication speed and conserving communication resources under varying network conditions
