Monitored Carrier Subset Management for Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices face challenges in efficiently managing a large number of carriers for radio signal measurements, leading to excessive processing resource usage and potential loss of network contact due to battery drain or infrequent measurements.
Innovation Solution
A method where a wireless communication device maintains a subset of monitored carriers by continuously assessing their quality, deleting low-quality carriers, and performing periodic searches for higher-quality carriers to replenish the subset, ensuring stable network contact without excessive resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a UE measures a large number of carriers to ensure optimal coverage and network contact, then the reliability of network connection is improved, but the processing resources and battery life are excessively consumed
Solution Approach 1:
The patent segments the carrier measurement process into two distinct phases: a first measurement phase with higher measurement frequency for initial carrier identification, and a second measurement phase with lower measurement frequency for ongoing monitoring. This segmentation allows the UE to reduce overall measurement activity while maintaining reliable network connection, thereby reducing battery consumption without compromising connection reliability.
Solution Approach 2:
The patent implements periodic carrier measurements with different periods for different phases of operation. During the first phase, carriers are measured more frequently to establish initial contact and identify suitable carriers. During the second phase, measurements are performed less frequently once carriers are established. This periodic action with varying frequencies allows the system to maintain reliable connections while significantly reducing energy consumption compared to continuous high-frequency measurements.
2Use of energy by moving object
If a UE reduces carrier measurements to conserve processing resources, then energy consumption is reduced, but the UE may lose contact with the network
Solution Approach 1:
The patent performs preliminary carrier measurements and evaluations during the first measurement phase to identify and select suitable carriers before reducing measurement frequency. By performing this preliminary action of carrier identification and quality assessment when measurement resources are still available, the system ensures that reliable carriers are established beforehand, allowing subsequent reduced-frequency measurements to maintain network contact without losing connection.
3Reliability
If a UE performs frequent carrier measurements to maintain network contact, then connection reliability is improved, but processing complexity and resource usage increase
Solution Approach 1:
The patent implements dynamic adjustment of measurement frequency based on operational phase and carrier status. The system transitions from a first measurement phase with higher frequency to a second measurement phase with lower frequency, dynamically adapting the measurement strategy to current needs. This dynamic approach maintains network contact stability while reducing processing complexity compared to static high-frequency measurements.
4Measurement precision
If a UE measures all configured carriers with equal frequency, then measurement completeness is improved, but processing efficiency decreases
Solution Approach 1:
The patent applies local quality by differentiating measurement frequency based on carrier status and operational phase. Instead of uniformly measuring all carriers at the same frequency, the system applies higher measurement frequency to carriers that require attention (during first measurement phase or when quality deteriorates) and lower frequency to stable carriers (during second measurement phase). This localized differentiation ensures measurement completeness for carriers that need it while improving overall processing efficiency by reducing redundant measurements.

AI summary
In a wireless communication device, a subset of available carriers is maintained as monitored carriers for performing measurements and the set of monitored carriers is replenished from only a subset of available carriers. Consequently, the wireless communication device does not have to measure a large number of carriers when looking for optimal radio network coverage. At the same time the method ensures that there is always an available “bucket” of monitored carriers that may be used for signal measurement. This means that the wireless communication device does not have to use a lot of processing resources (and thereby battery power) while still ensuring stable radio contact with the radio network or networks.
