Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks do not effectively account for survival time as a quality of service (QoS) requirement in feedback mechanisms, leading to potential downtime and inefficiencies in data packet transmission.
Innovation Solution
Implementing a method for consecutive data packet feedback that includes transmitting error indications and counter values to adjust transmission points, allowing for dynamic reconfiguration of feedback intervals and repetition of data packets based on loss tolerance thresholds, thereby enhancing reliability and reducing downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If feedback mechanisms do not account for survival time as a QoS requirement, then device complexity is reduced, but reliability of data transmission deteriorates
Solution Approach 1:
The patent implements a feedback mechanism that monitors consecutive data packet failures and uses this information to dynamically adjust transmission strategies. The receiver sends feedback indicating the number of consecutive failures, which triggers the transmitter to increase repetition factors or switch to multiple transmission points when thresholds are exceeded, thereby improving reliability without requiring complex pre-planning
Solution Approach 2:
The system dynamically adjusts transmission parameters based on real-time channel conditions. The repetition factor is not fixed but is modified according to the observed failure pattern, allowing the system to adapt to changing conditions and maintain reliability while keeping the base mechanism relatively simple
2Reliability
If data packets are transmitted from multiple transmission points when errors exceed thresholds, then reliability is improved, but device complexity increases
Solution Approach 1:
The system pre-configures multiple transmission points and repetition mechanisms in advance, but only activates them when the failure counter exceeds predetermined thresholds. This allows the complex multi-point transmission capability to be prepared beforehand without being constantly active, reducing operational complexity while maintaining reliability when needed
Solution Approach 2:
The system changes transmission parameters (such as repetition factor and number of transmission points) based on the failure counter value. When failures are within acceptable limits, simple single-point transmission is used. When thresholds are exceeded, parameters are adjusted to use multiple transmission points, balancing complexity and reliability dynamically
3Productivity
If feedback intervals are dynamically reconfigured based on loss tolerance thresholds, then productivity is improved, but device complexity increases
Solution Approach 1:
The system uses periodic feedback intervals for normal operation and switches to more frequent feedback only when failure thresholds are exceeded. This periodic approach maintains productivity during good conditions while allowing increased monitoring and control only when necessary, avoiding the constant complexity of fully dynamic adjustment
4Reliability
If repetition of data packets is configured when consecutive losses reach thresholds, then reliability is improved, but loss of time increases
Solution Approach 1:
The system takes preliminary action by configuring repetition and multiple transmission points before complete failure occurs. When the failure counter approaches critical thresholds, preventive retransmission is triggered to avoid total packet loss, thereby guaranteeing packet survival while minimizing the time lost compared to reactive retransmission after failure

AI summary
Apparatuses, methods, and systems are disclosed for consecutive data packet feedback. One method (1200) includes receiving (1202) a first set of consecutive data packets. The method (1200) includes transmitting (1204) feedback corresponding to the first set of consecutive data packets, wherein the feedback comprises: an error indication in response each data packet in the first set of consecutive data packets failing to be received correctly; a non-error indication in response to at least one data packet in the first set of consecutive data packets being received correctly; a counter value that indicates a consecutive number of data packet failures; or some combination thereof.
