Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a multi-link/multi-band mechanism is implemented to perform communication using multiple radio interfaces simultaneously, then throughput is improved, but device complexity increases
Solution Approach 1:
The communication apparatus segments the communication task across multiple radio interfaces (first radio interface and second radio interface operating at different bands). Each interface handles specific portions of the communication load, allowing parallel data transmission and thus improving overall throughput while managing complexity through functional segmentation.
Solution Approach 2:
The control unit is designed to universally manage multiple radio interfaces with different characteristics (2.4GHz and 5GHz bands). It can selectively activate appropriate interfaces based on communication conditions, making the system adaptable and efficient while providing a unified control mechanism that manages the inherent complexity.
2Productivity
If radio resources are allocated to multiple other apparatuses simultaneously, then communication efficiency is improved, but management complexity increases
Solution Approach 1:
The control unit performs preliminary actions by determining in advance which radio interfaces and resources should be allocated to which other apparatuses. It proactively manages resource allocation before communication begins, establishing a clear allocation plan that simplifies subsequent resource management and improves overall communication efficiency.
Solution Approach 2:
The system incorporates feedback mechanisms where the control unit receives information about communication conditions and adjusts resource allocation accordingly. This feedback loop enables efficient resource distribution among multiple apparatuses while simplifying management through automated, condition-based decision-making.
3Device complexity
If communication is performed using only one radio interface, then device complexity is reduced, but throughput is limited
Solution Approach 1:
The patent merges multiple radio interfaces (combining 2.4GHz and 5GHz band interfaces) into a unified communication system. The control unit coordinates both interfaces to work together, effectively doubling the available bandwidth and throughput capacity while managing complexity through integrated control rather than separate management.

AI summary
A communication apparatus capable of performing wireless communication with another apparatus by simultaneously using a first link and a second link performs, based on reception, from a first other apparatus, of a predetermined frame for executing communication by simultaneously using the first link and the second link, transmission, to the first other apparatus, of information indicating allocation of radio resources in the first link and the second link to the first other apparatus, and transmission, to a second other apparatus different from the first other apparatus, of information indicating allocation of the radio resources in one of the first link and the second link to the second other apparatus.
