Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LTE/NR and WLAN systems operate independently without resource allocation information sharing, then each system can maintain its own autonomous operation, but communication collisions occur between the systems
Solution Approach 1:
The patent introduces a base station as an intermediary that receives resource allocation information from the cellular system and forwards it to WLAN devices. This mediator enables information sharing between LTE/NR and WLAN systems without requiring direct complex interaction between them, thereby reducing communication collisions while maintaining operational autonomy of each system
Solution Approach 2:
The patent segments the resource allocation information into specific components (such as time-frequency resources, system frame structure) and selectively shares only the necessary portions with WLAN devices through the base station. This segmentation approach enables coordinated operation while avoiding unnecessary complexity in the information exchange mechanism
2Adaptability or versatility
If WLAN operates as autonomous distributed communication, then it provides flexibility in operation, but it becomes difficult to optimize communication indexes from the viewpoint of the entire system
Solution Approach 1:
The patent establishes a feedback mechanism where the base station receives resource allocation decisions from the cellular system and relays this information to WLAN devices. This feedback loop enables WLAN to adjust its operations based on cellular system resource allocation, thereby optimizing overall system communication efficiency while WLAN maintains its distributed autonomous operation mode
3Reliability
If resource allocation information is shared between LTE/NR and WLAN systems, then communication collisions are reduced, but the complexity of information transmission and processing increases
Solution Approach 1:
The base station acts as an intermediary that simplifies the information exchange process by centralizing the reception of resource allocation information from the cellular system and the distribution of this information to WLAN devices. This intermediary approach reduces the processing complexity at individual devices while maintaining reliable communication coordination

AI summary
The present technology relates to a wireless communication device, a wireless communication method, and a program, in which communication collisions with different communication systems can be reduced. The wireless communication device acquires information regarding a communication resource usable by the wireless communication device, the information being determined on the basis of transmission information transmitted from another first wireless communication device of another bidirectional second communication system different from a first communication system of the wireless communication device. The present technology can be applied to a wireless communication system including two different bidirectional communication systems.
