Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications systems, measurement gaps often collide with scheduled communication resources, leading to inefficiencies and potential data loss due to inflexible prioritization methods that favor either control or data traffic over measurement gaps.
Innovation Solution
The proposed solution involves a user equipment (UE) that can dynamically prioritize between communication resources and measurement gaps by skipping or canceling measurement gaps based on threshold durations and priority schemes, allowing for flexible communication resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement gaps are fixedly prioritized over communication resources, then measurement accuracy is improved, but communication efficiency deteriorates due to data loss and latency
Solution Approach 1:
The patent applies dynamics by transitioning from fixed prioritization to dynamic prioritization. The UE dynamically determines whether to skip or cancel a measurement gap based on real-time evaluation of threshold durations (first threshold between downlink control message and measurement gap start, second threshold between downlink control message and communication resource start). This dynamic adjustment allows the system to adapt measurement gap handling based on actual timing conditions, resolving the contradiction between measurement accuracy and communication efficiency.
Solution Approach 2:
The patent changes the parameter of prioritization from static to dynamic based on threshold duration evaluations. By evaluating whether the first threshold duration or second threshold duration is satisfied, the system changes the measurement gap status from fixed to flexible. This parameter change enables the system to maintain measurement accuracy when thresholds are not met while allowing communication resources to proceed when thresholds are satisfied, thus resolving the efficiency-accuracy contradiction.
2Productivity
If communication resources are fixedly prioritized over measurement gaps, then communication efficiency is improved, but measurement quality deteriorates due to skipped measurements
Solution Approach 1:
The system dynamically adjusts measurement gap handling based on threshold evaluations rather than fixed prioritization. When the first threshold duration is not satisfied or the second threshold duration is not satisfied, the UE skips or cancels the measurement gap, allowing communication resources to proceed efficiently. This dynamic approach ensures communication efficiency is maintained while measurement quality is preserved when timing conditions permit.
Solution Approach 2:
The patent changes the measurement gap parameter from fixed to dynamic based on threshold duration comparisons. By evaluating whether threshold durations are satisfied, the system flexibly adjusts measurement gap handling to balance communication efficiency and measurement quality, avoiding the need for fixed prioritization that would sacrifice one for the other.
3Loss of time
If measurement gaps are canceled or skipped frequently, then communication latency is reduced, but measurement coverage is lost
Solution Approach 1:
The system implements feedback through threshold-based evaluation of timing conditions. The UE continuously monitors whether the first threshold duration or second threshold duration is satisfied and uses this feedback to determine whether to skip or cancel measurement gaps. This feedback mechanism ensures that measurement gaps are only canceled when timing conditions explicitly permit, maintaining measurement coverage while reducing latency when appropriate.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting measurement gap status based on threshold duration evaluations. This allows the system to reduce communication latency by canceling measurement gaps when timing conditions are favorable while maintaining measurement coverage when thresholds are not satisfied, thus balancing latency reduction with measurement reliability.
4Adaptability or versatility
If flexible prioritization is implemented, then system adaptability is improved, but device complexity increases due to threshold evaluation logic
Solution Approach 1:
The patent implements flexible prioritization through parameter changes based on threshold duration evaluations. The UE evaluates whether the first threshold duration or second threshold duration is satisfied and adjusts measurement gap handling accordingly. This parameter-based approach provides system adaptability while keeping the control logic relatively simple, as it relies on straightforward threshold comparisons rather than complex decision algorithms.
Data Source
AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) flexibly prioritize between communication resources and measurement gaps to resolve collisions between communication resources and measurement gaps. For collisions between a dynamically scheduled communication resources and a measurement gap, a UE may communicate using the scheduled communication resource based on at least one of a time between reception of the downlink control message and a start of the measurement gap satisfying a first threshold duration or a second period of time between reception of the downlink control message and a start of the communication resource satisfying a second threshold duration. For collisions between periodic communication resources and periodic measurement gaps, a UE may either perform a measurement during the measurement gap or communicate using the communication resource based on a priority scheme associated with the measurement gap and the periodically scheduled communication resource.
