Survival Time Guarantee Control for Reliable Packet Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems struggle to support high-quality communication services with low transmission error rates, particularly in scenarios requiring survival time guarantees for time-sensitive communications, such as ultra-reliable and low-latency applications.
Innovation Solution
Implementing a survival time guarantee strategy in communication devices, where a processor determines, based on first information, whether to initiate strategies like resource adjustment, feedback reporting, and timer management to ensure timely and reliable packet or burst transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional communication systems are used, then device complexity is low, but transmission reliability is insufficient for time-sensitive applications
Solution Approach 1:
The system performs preliminary actions by determining whether to initiate a survival time guarantee strategy before actual data transmission. This advance decision-making allows the communication device to prepare appropriate transmission parameters and resource allocations, ensuring reliable delivery for time-sensitive packets while avoiding unnecessary complexity for non-critical traffic.
Solution Approach 2:
The system dynamically adjusts transmission parameters based on real-time conditions. The survival time guarantee strategy is not fixed but adaptively activated or deactivated based on the characteristics of incoming data packets and current network conditions, allowing the device to optimize between reliability and complexity on-demand.
2Reliability
If survival time guarantee strategy is initiated, then transmission error rate is reduced, but processing overhead increases
Solution Approach 1:
The survival time guarantee strategy is applied locally and selectively only to specific data packets that require time-sensitive delivery, rather than being applied system-wide to all traffic. This localized approach ensures high reliability for critical packets while minimizing processing overhead for non-critical traffic.
Solution Approach 2:
The system changes transmission parameters dynamically based on the survival time requirement. When a packet requires survival time guarantee, specific parameters such as transmission priority, resource allocation, and error correction levels are adjusted. This parameter-based approach allows flexible control of processing overhead while maintaining reliability where needed.
3Reliability
If resource adjustment is performed for survival time guarantee, then communication quality is improved, but system complexity increases
Solution Approach 1:
Resource adjustment is performed as a preliminary action when the survival time guarantee strategy is determined to be needed. The system proactively allocates appropriate transmission resources and configures communication parameters before data transmission begins, ensuring high communication quality while avoiding continuous complex resource management for all packets.
