Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies face challenges in switching flexibility and resource utilization, leading to inefficiencies and increased power consumption due to poor consensus on operation mode switching between stations and access points.
Innovation Solution
A communication method where stations and access points exchange frames to confirm operation mode switching, using specific frame formats to indicate switching parameters and timings, ensuring synchronized switching and reducing resource waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If operation mode switching is implemented to improve communication efficiency and reduce power consumption, then communication efficiency and power saving are improved, but switching flexibility and resource utilization deteriorate due to poor consensus between STA and AP
Solution Approach 1:
The patent implements a feedback mechanism where the STA sends a first frame to the AP after completing operation mode switching, notifying the AP of the switch. The AP then sends a third frame to confirm the switching parameters. This bidirectional feedback ensures both parties reach consensus on the switching state, resolving the contradiction between improving communication efficiency through OM switching and maintaining switching flexibility through proper coordination.
2Use of energy by moving object
If operation mode switching is implemented to reduce power consumption, then energy saving is improved, but resource utilization deteriorates due to lack of synchronized consensus on switching timing
Solution Approach 1:
The patent employs preliminary action by having the STA notify the AP of the operation mode switch before actually transmitting data in the new mode. The first frame is sent to inform the AP of the upcoming switch, and the third frame confirms the switching parameters in advance. This allows both parties to prepare for the switching timing, ensuring synchronized operation and preventing resource waste from mismatched transmissions.
3Productivity
If operation mode switching is implemented to improve communication efficiency, then throughput is improved, but communication reliability deteriorates due to potential consensus failure between STA and AP
Solution Approach 1:
The patent establishes a feedback loop where the STA sends a first frame to the AP indicating the operation mode switch has been completed, and the AP responds with a third frame containing confirmation of the switching parameters. This mutual confirmation mechanism ensures both parties have consistent understanding of the current operation mode, preventing communication errors and improving reliability while maintaining high throughput.
Data Source
AI summary
Embodiments of this application provides a communication method and a communication apparatus. In an example method, a station (STA) sends a first frame to an access point (AP). The first frame includes first information, and the first information indicates that a first operation mode (OM) has been switched to. The STA transmits a second frame in the first OM. The AP and the STA can reach a consensus on that the STA has switched to the first OM.
