Data Duplication Mode Indication for URLLC Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems lack an effective method for user equipment (UE) and network devices to determine the current data duplication mode, especially when the mode changes, which affects the transmission performance of ultra-reliable low latency communication (URLLC) services.
Innovation Solution
The proposed solution involves an indication method for data duplication mode, where UE receives and sends indication information to network devices to change, activate, or deactivate data duplication modes, allowing both UE and network devices to know the current mode, using various communication systems such as GSM, LTE, and 5G systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data duplication mode is changed to improve transmission performance, then reliability is improved, but the UE and network device cannot know the current mode causing information loss
Solution Approach 1:
The patent introduces feedback mechanisms where the UE sends indication information to the network device to report the current data duplication mode. This feedback loop ensures that both the UE and network device maintain consistent knowledge of the active duplication mode (first mode, second mode, or third mode), preventing information loss while allowing dynamic mode changes for improved transmission reliability.
2Adaptability or versatility
If data duplication mode changes frequently to adapt to different conditions, then adaptability is improved, but system complexity increases
Solution Approach 1:
The patent segments the data duplication indication system into distinct modes (first duplication mode, second duplication mode, third duplication mode) with clear transition rules. Each mode represents a specific configuration state, and the indication information clearly identifies which mode is active. This segmentation allows frequent mode changes for adaptability while maintaining manageable system complexity through well-defined state transitions.

AI summary
Disclosed is an indication method of data copying mode, including: receiving, by a terminal device, first indication information sent by a network device, wherein the first indication information is used to indicate the data copy mode to change. Or, the terminal device determines that the data copying mode is changed, and/or determines that the data copying mode is activated/deactivated. Further disclosed are another indication method of data copying mode, the terminal device, the network device, and a storage medium.
