Cellular High Power Mode for Wearable Link Budget
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cellular link budget limited devices, such as wearable devices, often experience sub-optimal radio conditions, leading to increased power consumption and poor user experience due to their limited power supply and form factor constraints, which complicates maintaining a network connection within a tolerable optimal range.
Innovation Solution
A method and system that detect high power states in network connections by monitoring events like RACH failures, retransmission attempts, and uplink transmission parameters, activating high power mode settings to reduce usage and conserve power while minimizing user experience impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device maintains network connection operations under sub-optimal radio conditions, then the user experience is degraded, but the power consumption increases significantly
Solution Approach 1:
The system dynamically adjusts network connection settings based on detected high power states. When sub-optimal radio conditions are detected, the device transitions from normal operation to a high power mode with reduced network usage, dynamically adapting to environmental conditions to balance user experience with power conservation
Solution Approach 2:
The invention changes operational parameters by detecting specific events (RACH failures, retransmission attempts, uplink transmission parameters) that indicate high power states. Upon detection, the system modifies network connection parameters to reduce power consumption while attempting to maintain acceptable user experience through selective operation reduction
2Use of energy by moving object
If the device reduces network operations to conserve power, then power consumption decreases, but user experience deteriorates further
Solution Approach 1:
The system implements feedback mechanisms by continuously monitoring network events and power state indicators. This feedback loop allows the device to detect when high power states occur and adjust operations accordingly, providing a controlled way to reduce power consumption while monitoring the impact on user experience to prevent excessive degradation
3Reliability
If the device maintains optimal radio conditions through active network operations, then user experience is preserved, but the limited power supply is depleted faster
Solution Approach 1:
The system applies partial action by selectively reducing certain network operations during high power states rather than completely shutting down connectivity. This approach maintains essential user experience functions while reducing overall power consumption to extend battery life, implementing a balanced reduction rather than complete operation cessation

AI summary
A device, system, and method uses a high power mode for a cellular connection. The method is performed at a device that is configured to establish a network connection to a network. The method includes detecting a number of at least one event that has occurred over a time period, the at least one event associated with operations used through the network connection, the at least one event indicative of a power to perform the operations that is greater than a predetermined power. When the number is at least a predetermined threshold, the method includes identifying the network connection as being in a high power state. The method includes activating settings when the network connection is in the high power state, the settings reducing a usage of the operations over the network connection.
