Engineering Contradiction Analysis
1Ease of operation
If random access control is used in wireless LAN systems, then any communication device can transmit data after a predetermined random transmission waiting time, but data requiring shorter latency cannot be effectively prioritized and transmitted
Solution Approach 1:
The patent applies preliminary action by having communication devices estimate transmission capacity in advance and determine predetermined transmission capacities before actual data transmission occurs. The control unit calculates what data can be transmitted within expected random access control waiting times and sets transmission capacities accordingly, enabling prioritized latency-sensitive data to be prepared and transmitted efficiently when opportunities arise.
Solution Approach 2:
The patent implements dynamics by making transmission capacity adaptive rather than fixed. The control unit dynamically adjusts transmission capacity based on elapsed time of transmission intervals and estimated random access control waiting times. This allows the system to optimize transmission parameters in real-time according to actual network conditions, resolving the contradiction between simple access control and efficient prioritized transmission.
2Speed
If data transmission capacity is increased to improve transmission speed, then data can be transmitted faster, but transmission reliability decreases due to congestion and collisions in wireless LAN
Solution Approach 1:
The patent applies feedback by having the control unit continuously monitor transmission status, estimated random access control waiting times, and actual transmission capacity. Based on this feedback, the system adjusts transmission capacity and timing to optimize both speed and reliability. The feedback mechanism ensures that transmission parameters are modified according to actual network conditions, preventing congestion while maintaining efficient data transfer.
Solution Approach 2:
The patent implements parameter changes by dynamically modifying transmission capacity parameters based on elapsed time and estimated waiting times. The control unit changes transmission parameters such as data amount and timing according to actual network conditions, allowing the system to adapt transmission behavior to maintain both speed and reliability in the wireless LAN environment.
3Device complexity
If transmission capacity is determined based on fixed time intervals, then transmission control is simplified, but transmission efficiency decreases in congested wireless networks with varying random access control delays
Solution Approach 1:
The patent applies dynamics by transitioning from fixed time interval transmission control to dynamic transmission capacity determination. The control unit calculates transmission capacity based on elapsed time of transmission intervals and estimated random access control waiting times, making the transmission control adaptive to actual network conditions. This dynamic approach maintains simplicity while significantly improving transmission efficiency in congested wireless networks.
Solution Approach 2:
The patent implements parameter changes by making transmission capacity a variable parameter rather than a fixed value. The control unit adjusts transmission capacity parameters based on elapsed time and network conditions, allowing the system to optimize transmission efficiency without increasing control complexity. This parameter adaptation enables efficient data transmission while maintaining manageable control mechanisms.
