Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data transmission and reception are scheduled through multiple links without coordination, then the device can utilize multiple frequency bands for communication, but data transmission speed and service quality are reduced due to overlapping transmission periods
Solution Approach 1:
The patent implements dynamic scheduling of data transmission and reception periods across multiple links. The processor dynamically adjusts the timing parameters of each link based on current communication conditions, preventing overlapping transmission periods while maintaining adaptability to different communication scenarios and services
Solution Approach 2:
The patent changes the temporal parameters (transmission periods, reception periods, timing offsets) of multiple links to avoid overlap. By adjusting these parameters dynamically, the system maintains multi-link versatility while ensuring that data transmission speed is not degraded by concurrent operations on the same device
2Adaptability or versatility
If data transmission and reception are scheduled through multiple links simultaneously, then communication coverage is expanded, but service quality is lowered due to resource conflicts
Solution Approach 1:
The system dynamically schedules transmission and reception periods for each link based on real-time conditions. This dynamic approach ensures that service quality is maintained across multiple frequency bands by preventing resource conflicts, while still allowing the device to operate on multiple links simultaneously for expanded coverage
3Adaptability or versatility
If the device operates in both soft AP mode and STA mode on different links, then communication flexibility is improved, but scheduling complexity increases
Solution Approach 1:
The patent implements a universal scheduling mechanism that handles both soft AP mode and STA mode operations through a single processor-based scheduling system. This multi-functional approach manages the complexity of dual-mode operation on multiple links while maintaining communication flexibility, by providing a unified method for coordinating transmission and reception periods across different operational modes

AI summary
An electronic device may include a communication circuit configured to transmit and receive data to and from a first external electronic device through a first link of short-range wireless communication while the electronic device operates in a soft AP mode and to transmit and receive data to and from a second external electronic device through a second link of the short-range wireless communication while the electronic device operates in an STA mode; and a processor, wherein the processor may be configured to identify a control method of the first link and the second link, and to configure at least one parameter related to a period during which data transmission and/or reception through the second link is possible based on at least one parameter related to a period during which data transmission and/or reception through the first link is possible corresponding to identifying that the control method does not simultaneously perform data transmission and/or reception through the first link and the second link. Further, various other embodiments are possible.
