Solution Overview
Problem
Current wireless communication systems lack efficient methods for enabling concurrent infrastructure and peer-to-peer modes of operation, particularly in devices like multifunctional peripherals, which hinders seamless communication and channel management between access points and terminal devices.
Innovation Solution
A communication apparatus with a processor and memory that enables both infrastructure and peer-to-peer modes by receiving trigger frames and managing communication channels, allowing it to operate as a master station and control data transmission without requesting carrier sensing, thereby optimizing channel usage and reducing communication latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the communication apparatus enables both infrastructure mode and peer-to-peer mode concurrently, then communication versatility is improved, but channel management complexity increases
Solution Approach 1:
The communication apparatus segments channel management by designating specific channels for infrastructure mode and other channels for peer-to-peer mode. The control unit divides the communication spectrum into distinct segments, assigning each mode to dedicated channels to avoid interference and simplify management of concurrent operations.
Solution Approach 2:
The control unit dynamically switches between infrastructure mode and peer-to-peer mode based on operational requirements. When peer-to-peer communication is needed, the apparatus transitions from infrastructure mode to peer-to-peer mode on designated channels, enabling flexible adaptation while maintaining clear channel separation.
2Reliability
If carrier sensing is executed for every data transmission, then communication reliability is improved, but transmission time increases
Solution Approach 1:
Carrier sensing is executed in advance during the channel selection process before actual data transmission begins. The control unit performs preliminary carrier sensing to identify available channels, then commits to those channels for subsequent transmissions, avoiding repeated sensing overhead during active communication.
Solution Approach 2:
The patent extracts carrier sensing operations from the data transmission pathway itself and places them in the channel selection phase. By separating sensing operations from transmission operations, the system performs sensing only when necessary for channel selection, not continuously during every transmission cycle.
3Adaptability or versatility
If the communication apparatus operates as both infrastructure access point and peer-to-peer master station, then functional versatility is improved, but operational complexity increases
Solution Approach 1:
The apparatus segments its operational roles by designating different communication channels for infrastructure access point functions and peer-to-peer master station functions. The control unit manages these segmented roles independently, switching between them based on mode requirements without requiring complex coordination between conflicting functions.
Solution Approach 2:
Different quality attributes are applied to different operational modes: infrastructure mode operates with centralized control and coordination characteristics, while peer-to-peer mode operates with distributed control characteristics. The control unit applies appropriate operational qualities locally to each mode rather than attempting a unified approach.

AI summary
In a case where a communication apparatus operates as a master station for determining a communication channel used in wireless communication, the communication apparatus does not transmit information indicating execution of carrier sensing, to a slave station apparatus connected to the master station.
