Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no scheme for an interaction process of first fallback request information between a first node (e.g., a terminal) and a second node or third node in existing wireless network architectures, particularly in 6G scenarios with diverse intelligent automated devices requiring extremely low latency, high reliability, and ultra-wide bandwidth.
Innovation Solution
An information transmission method and apparatus that includes sending first fallback request information to a third node or a second node, which includes a fallback reason, functional module information, and a start time of the fallback, along with the ability to receive and act on fallback confirmation information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the existing wireless network architecture is used, then the network can maintain basic communication functionality, but it cannot meet the emerging application demands of the post-5G/6G era with highly differentiated capabilities and massive access
Solution Approach 1:
The patent introduces dynamic capability negotiation and adaptation mechanisms where network nodes can dynamically adjust their operational parameters and capabilities based on real-time conditions. The fallback request information enables nodes to dynamically switch between different operational modes (5G NR mode and legacy mode) depending on the communication scenario, thereby resolving the contradiction between adaptability to differentiated capabilities and communication efficiency.
Solution Approach 2:
The patent changes key parameters of the communication system by introducing a fallback mechanism that allows nodes to switch between different operational modes. The fallback request information includes parameters such as fallback reason, functional module information, and start time, which enable parameter changes in the system configuration to match the specific needs of different applications and network conditions.
2Adaptability or versatility
If more intelligent automated devices are connected to meet diverse application demands, then the network coverage and functionality are expanded, but the contradiction between endless growth of service demands and limited wireless resources becomes more prominent
Solution Approach 1:
The patent implements a feedback mechanism where nodes send fallback request information to indicate when they need to switch to legacy mode. This feedback loop allows the network to monitor resource usage patterns and dynamically adjust the allocation of wireless resources, enabling the network to serve more devices while optimizing resource utilization based on actual demand and conditions.
Solution Approach 2:
The dynamic capability negotiation allows the network to flexibly allocate resources based on the specific needs of connected devices. By enabling nodes to dynamically select between 5G NR mode and legacy mode, the system can optimize resource distribution across a larger number of devices, resolving the contradiction between expanded network coverage and limited wireless resources.
3Reliability
If the combination of data channel generation methods of NR is used, then the system can maintain current communication standards, but it greatly limits the data transmission efficiency of terminals and affects the system spectrum efficiency
Solution Approach 1:
The patent enables terminals to dynamically switch between different data channel generation methods based on the communication scenario. The fallback mechanism allows terminals to use 5G NR methods when available for high efficiency, but switch to legacy methods when necessary for compatibility, thereby resolving the contradiction between maintaining communication standard compliance and achieving optimal data transmission efficiency.
Solution Approach 2:
The system changes the parameter of data channel generation method based on network conditions and terminal capabilities. The fallback request information triggers parameter changes in the data channel configuration, allowing the system to optimize between NR-based efficient transmission and legacy-compatible transmission methods depending on the specific operational context.
