Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If trigger frames are transmitted frequently to ensure reliable uplink communication, then communication reliability is improved, but wireless medium utilization efficiency deteriorates due to excessive padding and resource consumption
Solution Approach 1:
The patent implements a feedback mechanism where the station transmits trigger frame feedback to the access point based on downlink signals and uplink transmission performance. The access point uses this feedback to dynamically adjust trigger frame scheduling parameters, optimizing the balance between communication reliability and medium utilization efficiency.
Solution Approach 2:
The patent employs dynamic adjustment of trigger frame transmission parameters based on real-time feedback. The access point modifies scheduling intervals, resource allocation, and trigger frame characteristics adaptively to match actual communication needs, transitioning from static to dynamic resource management.
2Stability of the object's composition
If trigger frames are transmitted more frequently to maintain connection stability, then connection stability is improved, but power consumption increases due to unnecessary transmissions
Solution Approach 1:
The feedback mechanism enables the access point to monitor connection stability metrics and adjust trigger frame transmission frequency accordingly. When connection stability is sufficient, the access point reduces transmission frequency, thereby lowering power consumption while maintaining stability.
Solution Approach 2:
The patent changes transmission parameters such as trigger frame interval and resource allocation based on feedback-induced parameter adjustments. This allows optimization of power consumption by reducing unnecessary transmissions while maintaining connection stability through adaptive parameter modification.
3Reliability
If resource allocation for uplink transmissions is increased to improve data transmission reliability, then data transmission reliability is improved, but medium utilization efficiency deteriorates due to excessive padding
Solution Approach 1:
The trigger frame feedback mechanism provides the access point with information about actual data transmission needs and padding levels. Based on this feedback, the access point adjusts resource allocation to match actual requirements, reducing energy waste from excessive padding while maintaining data transmission reliability.
Solution Approach 2:
The patent dynamically modifies resource allocation parameters such as transmission time slots, frequency resources, and power levels based on feedback. This enables precise matching of allocated resources to actual data transmission needs, eliminating energy waste from over-allocation and excessive padding.

AI summary
A communication system is provided in which access points (APs) communicate with stations (STAs). An AP may communicate with a STA according to a communications protocol that implements trigger-based uplink (UL) transmission such as an IEEE 802.11 protocol. The AP may transmit trigger frames to the STA that trigger UL transmissions by the STA under the protocol. The STA may generate trigger frame feedback based at least in part on downlink signals transmitted by the AP. The STA may transmit the trigger frame feedback to the AP. The AP may adjust scheduling of the trigger frames based on the trigger frame feedback. This may include adjusting how often the AP transmits the trigger frames and/or adjusting a resource allocation of the trigger frames. The trigger frame feedback may serve to maximize the efficiency with which the STA and the AP utilize the propagation medium between the STA and the AP.
