Uplink Resource Request Timing for Continuous LBT Failure Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication systems face challenges in successfully reporting consistent Listen-Before-Talk (LBT) failures due to inconsistent resource availability and failure detection, leading to inefficient resource utilization and potential resource waste.
Innovation Solution
A communication method and apparatus that triggers and cancels uplink resource requests based on defined conditions, ensuring timely and efficient reporting of LBT failures by specifying triggering and cancellation times, preventing mutual interference, and optimizing resource use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal continuously requests uplink resources to report LBT failures, then the reporting reliability is improved, but the resource utilization efficiency deteriorates due to potential resource waste
Solution Approach 1:
The terminal performs preliminary actions by triggering first information before actual LBT failure occurs, based on predicted conditions. This allows the system to prepare resource requests in advance, ensuring reliable reporting while avoiding continuous resource consumption by canceling the trigger when conditions change.
Solution Approach 2:
The system dynamically adjusts the resource request state by introducing a cancellation mechanism. The terminal can cancel the triggered first information when specific conditions are met (such as when LBT failure is resolved or resource is no longer needed), transforming a static continuous request into a dynamic conditional request that optimizes both reliability and efficiency.
2Reliability
If the terminal triggers first information based on any LBT failure condition, then the reporting completeness is improved, but the device complexity increases due to multiple condition judgments
Solution Approach 1:
The complex condition judgment is segmented into distinct, manageable parts: a first condition for triggering (LBT failure detection) and a second condition for cancellation (failure resolution or resource unavailability). This segmentation simplifies the logic by breaking down the complex decision-making process into clear, separate judgment steps.
Solution Approach 2:
The system implements feedback mechanisms where the terminal continuously monitors LBT status and resource availability to determine whether to trigger or cancel first information. This feedback loop ensures complete reporting by adapting to changing conditions while maintaining manageable complexity through structured decision logic.
3Speed
If the terminal sends first information immediately upon triggering, then the response speed is improved, but the resource waste increases due to potential unnecessary requests
Solution Approach 1:
The terminal triggers first information in advance based on predicted LBT failure conditions rather than waiting for actual failure occurrence. This preliminary action enables fast response when needed while the cancellation mechanism prevents resource waste by stopping requests when conditions change, achieving both speed and efficiency.
Solution Approach 2:
The system dynamically controls the timing of resource requests by allowing immediate triggering when conditions are met while providing the flexibility to cancel when conditions change. This dynamic approach optimizes response speed for critical moments while avoiding unnecessary resource consumption through conditional cancellation.
