UE Measurement Gap Adjustment for Continuous Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in managing measurement gaps due to unsatisfactory data traffic criteria, leading to unnecessary transitions that disrupt ongoing data transmission and reception.
Innovation Solution
A user equipment (UE) determines whether data traffic criteria are satisfied during a tune away period and adjusts its configuration accordingly, disregarding measurement gaps when criteria are met, thereby maintaining connectivity and optimizing data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement gap configuration is applied to enable frequency measurements, then measurement capability is improved, but data transmission continuity deteriorates due to tune away periods
Solution Approach 1:
The patent applies dynamics by making the measurement gap configuration adjustable and conditional rather than static. The UE dynamically evaluates data traffic criteria (such as packet loss rate, latency, throughput thresholds) and adapts the measurement gap configuration accordingly, transitioning between different measurement gap patterns or suspending measurements when data transmission requirements are not met. This dynamic adaptation resolves the contradiction by allowing measurement capability when conditions permit while maintaining data transmission continuity when conditions require it.
2Measurement precision
If measurement gaps are frequently implemented for network optimization, then network performance monitoring is improved, but data transmission efficiency deteriorates due to interruptions
Solution Approach 1:
The patent applies parameter changes by modifying the measurement gap configuration parameters (such as measurement gap pattern, periodicity, duration) based on evaluated data traffic criteria. When criteria indicate poor data transmission conditions (high packet loss, excessive latency, low throughput), the system changes parameters to reduce or suspend measurement gaps, thereby improving data transmission efficiency. When criteria indicate good conditions, parameters are adjusted to enable more frequent measurements for better network performance monitoring.
3Reliability
If measurement gap configuration is enforced to ensure accurate measurements, then measurement reliability is improved, but data transmission stability deteriorates due to forced tune away periods
Solution Approach 1:
The patent applies feedback by continuously evaluating data traffic criteria (packet loss rate, latency, throughput) and using this feedback to adjust the measurement gap configuration. The system monitors data transmission stability and feeds this information back to the measurement management function, which then adjusts measurement reliability accordingly. When data transmission becomes unstable, feedback triggers a reduction in measurement frequency or suspension of measurement gaps, thereby stabilizing data transmission while maintaining adequate measurement reliability when conditions permit.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a measurement gap configuration from a base station, wherein the measurement gap configuration includes a tune away period. The UE may determine whether one or more data traffic criteria are satisfied for the tune away period. The UE may disregard the measurement gap configuration based at least in part on the determination of whether the one or more data traffic criteria are satisfied. The UE may remain tuned to the base station during the tune away period based at least in part on the determination of whether the one or more data traffic criteria are satisfied. Numerous other aspects are provided.
