Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices in communication systems may enter un-synchronous states due to power mode change failures, leading to operation collisions and inefficiencies.
Innovation Solution
Electronic devices notify each other of power mode change failures using burst ending signals with error indication signals to abort power mode configurations, preventing un-synchronous states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power mode change operation is performed without error notification mechanism, then device complexity is reduced, but reliability deteriorates due to un-synchronous states and operation collisions
Solution Approach 1:
The patent implements a feedback mechanism where the transmitting device sends a burst ending signal with error indication when power mode change fails, and the receiving device responds by aborting its power mode configuration. This feedback loop ensures both devices maintain synchronous states and prevents operation collisions, directly resolving the reliability issue without requiring complex additional hardware.
Solution Approach 2:
The burst ending signal serves as an intermediary carrier that conveys error information from the transmitting device to the receiving device. By embedding error indication within the existing burst ending signal structure, the patent avoids adding separate complex error notification channels while still achieving reliable error communication and synchronous state maintenance.
2Device complexity
If error notification is implemented using existing burst ending signal, then device complexity is minimized, but measurement precision deteriorates due to lack of dedicated error indication capability
Solution Approach 1:
The patent makes the burst ending signal multi-functional by embedding error indication capability within it. The same signal structure that indicates burst closure now also conveys error information through specific error indication fields. This universal approach allows one signal to serve multiple purposes without increasing device complexity, while maintaining precise error indication through dedicated error fields within the signal.

AI summary
A method for an electronic device in a power mode change operation, an electronic device, and a communication system are provided. In an embodiment, the method comprises the following steps. During the power mode change operation, the electronic device detects whether a power mode change failure occurs in the electronic device after transmitting a power mode change request frame. The electronic device transmits the first burst ending signal to notify another electronic device of the power mode change failure in the electronic device, wherein the first burst ending signal indicates burst closure and includes a first error indication signal to indicate the power mode change failure in the electronic device. Thus, in response to the first burst ending signal, the other electronic device can abort a power mode configuration to avoid undesirable un-synchronous states.
