Communication Method for Managing Transmission Survival Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in ensuring service transmission performance, particularly in scenarios requiring ultra-reliable and low-latency communication, where consecutive packet errors can lead to service failure, and the survival time parameter is not effectively managed to prevent such failures.
Innovation Solution
A communication method where a network device sends a first parameter to a terminal device, including related information of a counter and a timer, to trigger specific behaviors that ensure service transmission performance, such as adjusting transmission parameters or modes, to prevent service failures due to packet errors.

Engineering Contradiction Analysis
1Reliability
If conventional transmission methods are used without survival time management, then device complexity is reduced, but service transmission reliability deteriorates due to consecutive packet errors
Solution Approach 1:
The network device pre-configures survival time parameters (counter thresholds and timer durations) before transmission begins. These parameters are established in advance based on service requirements, allowing the terminal device to autonomously manage transmission reliability without complex real-time decisions, thus improving reliability while maintaining simplicity
Solution Approach 2:
The patent implements a feedback mechanism where the terminal device monitors transmission status using counters and timers, and reports to the network device when the counter reaches its threshold or timer expires. This feedback loop enables automatic adaptation of transmission parameters based on actual channel conditions, improving service transmission reliability through continuous monitoring and reporting
2Reliability
If aggressive error prevention measures are implemented, then service transmission reliability improves, but transmission latency increases due to additional control signaling
Solution Approach 1:
Survival time parameters including counter thresholds and timer durations are pre-configured by the network device before actual transmission occurs. This preliminary configuration eliminates the need for real-time parameter negotiation and complex runtime decisions, reducing latency while maintaining reliability through pre-planned error prevention strategies
Solution Approach 2:
The terminal device autonomously manages transmission reliability using the pre-configured survival time parameters. It independently monitors packet transmission success, increments counters on errors, and triggers retransmission or reporting when thresholds are met, without requiring continuous network device intervention. This self-service approach reduces control signaling overhead and transmission latency
