Dynamic Frequency Band Selection for Attenuation Activities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) experiences signal loss and poor network performance during attenuation activities, such as being submerged in water, due to conventional network prioritization mechanisms that lock onto higher frequency bands without considering the attenuation environment, leading to increased power consumption and poor user experience.
Innovation Solution
A method and device that dynamically prioritize available frequency bands based on the attenuation activity state, selecting lower frequency bands when an attenuation activity is detected to minimize signal loss and improve network connectivity, such as when submerged in water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the UE locks onto higher frequency bands set by the network, then data exchange rate is improved, but signal loss increases during attenuation activities
Solution Approach 1:
The patent implements dynamic frequency band selection by transitioning from a static network-configured priority list to a dynamic selection mechanism that adapts to real-time activity states. The UE dynamically switches between using network-provided priorities and activity-based priorities depending on whether an attenuation activity is detected, ensuring optimal performance under varying conditions.
Solution Approach 2:
The patent changes the priority parameter of frequency bands based on activity state. When attenuation activity is detected, the system generates activity-based priorities that favor lower frequency bands over network-provided priorities, effectively changing the selection parameter to optimize for signal reliability rather than raw data rate.
2Reliability
If the UE uses conventional network prioritization mechanisms, then network connection is established, but power consumption increases during attenuation activities
Solution Approach 1:
The UE performs self-service by autonomously detecting its own activity state through sensors and automatically adjusting frequency band selection accordingly. This eliminates the need for continuous network signaling and manual intervention, reducing power consumption while maintaining connection reliability during attenuation activities.
3Ease of operation
If the UE maintains connectivity during attenuation activities, then user experience is improved, but signal loss occurs without adaptive frequency selection
Solution Approach 1:
The system performs preliminary action by pre-configuring activity-based priority lists for different attenuation scenarios before they occur. When an attenuation activity is detected, the UE can immediately switch to the pre-computed activity-based priorities, avoiding the need for real-time calculations and ensuring rapid adaptation to minimize signal loss and maintain user experience.

AI summary
A device, system, and method select a frequency band during an attenuation activity state. The method is performed at a device that is configured to establish a network connection to a network having a first priority of available frequency bands set by the network. The method includes identifying an attenuation activity state. The method includes generating a second priority of the available frequency bands based on the attenuation activity state. The method includes selecting one of the available frequency bands based on the second priority to establish the network connection.
