Engineering Contradiction Analysis
1Productivity
If high transmission parameters (high stream quantity or high bandwidth) are used to transmit data, then data transmission rate is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic transmission parameter switching by continuously monitoring service scenarios, traffic features, channel status, and instant messaging performance. The system adjusts transmission parameters (bandwidth, stream quantity, MCS) in real-time based on actual communication conditions, transitioning from static high parameters to adaptive parameters that match current needs, thereby reducing power consumption while maintaining adequate transmission rates.
Solution Approach 2:
The patent changes transmission parameters (bandwidth, stream quantity, modulation and coding scheme) based on monitored conditions. When service scenarios indicate lower data requirements or channel conditions deteriorate, the system switches to parameter sets with lower bandwidth values, reduced stream quantities, or adjusted MCS levels, directly reducing power consumption while adapting to actual communication demands.
2Use of energy by moving object
If transmission parameters are reduced to lower power consumption, then power consumption is improved, but communication quality may deteriorate
Solution Approach 1:
The patent employs feedback mechanisms by continuously monitoring instant messaging performance, channel status, and traffic features. This feedback loop allows the system to detect when communication quality begins to deteriorate and automatically adjust transmission parameters upward to maintain quality standards, ensuring that power reduction does not compromise communication reliability.
Solution Approach 2:
The system dynamically adjusts transmission parameters based on real-time monitoring of communication quality metrics. When quality thresholds are approached or exceeded, the system automatically increases parameters to maintain reliability, creating a balanced adaptive system that optimizes power consumption without sacrificing communication quality.

AI summary
A transmission parameter switching method and system, and a related apparatus are provided. In the method, a STA may determine a target transmission parameter based on transmission information delivered by an AP and one or more of a current service scenario, a current traffic feature, a current channel state, and current instant messaging performance of the STA. Power consumption of transmitting data by the STA based on the target transmission parameter is lower than power consumption of transmitting data by the STA based on current transmission parameter. Implementing the technical solutions provided in this application can reduce power consumption of the STA.
