Early Cell Measurement Reporting With Timer-Adaptive Targets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing early measurement reporting systems in wireless communication, such as NR and LTE, suffer from inconsistent reporting timing, unclear measurement validity, and potential for outdated or poor-quality measurements due to the use of timer T331, leading to inefficiencies in multi-carrier operation configurations.
Innovation Solution
Implement a timer-adaptive procedure for early measurement reporting that differentiates between first and second performance targets before and after the expiration of a timer, allowing for consistent wireless device behavior and enabling timely, differentiated measurement reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If timer T331 is used to control measurement duration, then measurement reporting can be initiated, but the measurements may become outdated or poor-quality by the time reporting occurs
Solution Approach 1:
The patent applies dynamics by making the measurement performance target adaptive rather than static. The wireless device dynamically adjusts the measurement performance target based on whether the timer is running or has expired. When the timer is running, a first performance target is used; when expired, a second performance target is used. This dynamic adaptation allows the system to maintain reliable measurements even after timer expiration by adjusting measurement requirements according to the current timing state.
Solution Approach 2:
The patent changes the measurement performance target parameter based on timer state. The system transitions between two distinct performance target states: a first performance target when the timer is running and a second performance target when the timer has expired. This parameter change enables the system to differentiate between timely and delayed measurements, allowing outdated measurements to be reported with appropriate quality expectations rather than being discarded entirely.
2Productivity
If early measurement reporting is implemented, then multi-carrier operation can be configured, but reporting timing becomes inconsistent and measurement validity unclear
Solution Approach 1:
The patent implements feedback by having the wireless device provide information about the timer state associated with measurements. The network receives indication of whether measurements were taken while the timer was running or after expiration. This feedback mechanism allows the network to understand the validity and timeliness of received measurements, enabling informed decisions about multi-carrier configuration based on measurement freshness without losing critical validity information.
Solution Approach 2:
The patent segments measurement reporting into two distinct categories based on timer state: measurements taken while the timer is running and measurements taken after timer expiration. By segmenting the measurement process and reporting based on this temporal division, the system maintains clear distinction between timely and delayed measurements, preventing confusion about measurement validity while enabling both types to contribute to multi-carrier operation configuration.
3Adaptability or versatility
If measurements are performed after timer expiration, then reporting can still occur, but performance targets become unclear
Solution Approach 1:
The patent applies dynamics by implementing two distinct performance targets that the wireless device switches between based on timer state. When the timer is running, the first performance target applies; when expired, the second performance target applies. This dynamic switching simplifies device complexity by providing clear, predetermined performance expectations for each timer state rather than requiring continuous evaluation of measurement freshness.

AI summary
A method, system and apparatus are disclosed. According to one or more embodiments, a wireless device configured to communicate with a network node is provided. The wireless device configured to: before expiration of a first timer, perform first measurements of a cell while meeting a first performance target, and after the first timer has stopped, perform second measurements of the cell while meeting a second performance target different from the first performance target.
