Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, communication terminals under an access point face difficulties in flexibly transitioning from centralized communication mode to autonomous decentralized communication mode due to predetermined duration settings (TXOP or NAV) in the centralized communication mode.
Innovation Solution
A communication apparatus and method that generate and transmit multiple types of transition information to facilitate flexible transitions from centralized communication mode to another mode, allowing communication terminals to switch between modes more efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the duration of centralized communication mode is predetermined by TXOP or NAV to a fixed length, then the centralized communication can be maintained for a stable period, but the communication terminal cannot flexibly transition to autonomous decentralized communication mode
Solution Approach 1:
The patent makes the duration of centralized communication mode dynamic rather than fixed. The access point determines the duration based on actual communication needs, and can adjust it dynamically. This allows the system to transition from centralized to autonomous decentralized mode at appropriate times, resolving the contradiction between maintaining stable centralized communication and enabling flexible mode transition.
Solution Approach 2:
The patent changes the parameter of communication mode duration from a fixed predetermined value to a variable that can be adjusted based on system state. By allowing the duration parameter to change according to actual needs, the system achieves both stable centralized communication when needed and flexible transition to autonomous mode when appropriate.
2Adaptability or versatility
If multiple types of transition information are generated and transmitted, then the communication terminal can flexibly transition to another mode, but the frame structure and information processing become more complex
Solution Approach 1:
The patent segments transition information into different types (first transition information for autonomous decentralized mode, second transition information for other modes). This segmentation allows the access point to transmit only the relevant transition information based on the current communication state, reducing unnecessary information processing complexity while maintaining flexible mode transition capability.
Solution Approach 2:
The patent implements partial action by transmitting only the necessary transition information rather than all possible types. The access point determines which transition information to transmit based on actual needs, avoiding the complexity of processing and transmitting excessive information while still enabling flexible mode transitions when required.

AI summary
The present technology aims to achieve flexible transition of a communication apparatus from a centralized communication mode to another mode. A communication apparatus includes: a transition information generation unit that generates a plurality of pieces of different transition information related to transition from a first mode in which centralized communication is performed by an access point to a second mode in which no centralized communication by an access point is performed; and a frame generation unit that generates a frame containing the transition information.
