Network Device Data Transmission Mode Selection for 5G URLLC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data transmission methods in 5G networks, such as Packed Duplication, face challenges in dynamically adapting to changing channel conditions and quality of service requirements, affecting system capacity and reliability, especially for ultra-reliable low-latency communication (URLLC).
Innovation Solution
A method where a network device determines the data transmission mode for a terminal device based on input parameters like channel-specific measurements, data transmission mode indications, uplink channel conditions, and quality of service requirements, allowing for flexible selection between link switching, link aggregation, and packet duplication modes.

Engineering Contradiction Analysis
1Reliability
If packet duplication transmission mode is used to improve data transmission reliability, then transmission reliability is improved, but system capacity is reduced
Solution Approach 1:
The patent implements dynamic switching between packet duplication mode and non-duplication mode based on real-time channel conditions and QoS requirements. The network device determines whether to activate packet duplication by evaluating channel quality indicators and service requirements, allowing the system to adapt transmission reliability and resource consumption dynamically rather than using a fixed duplication approach.
2Reliability
If packet duplication is activated to ensure reliable transmission, then transmission reliability is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent changes the parameter of duplication activation from a static configuration to a dynamic state based on channel conditions and QoS parameters. The network device monitors channel quality indicators and service requirements, then adjusts the duplication activation state accordingly, optimizing the balance between transmission reliability and resource consumption by activating duplication only when necessary.
3Reliability
If dynamic adaptation to channel conditions is implemented, then transmission reliability is improved, but system complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the network device monitors channel conditions and QoS requirements, then determines the appropriate duplication activation state. The system uses feedback from channel quality indicators and service requirements to dynamically adjust transmission mode, achieving adaptive reliability improvement without requiring overly complex decision-making architectures.
