Multimode RAT Control for Throughput and Power Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cellular devices often face inefficiencies in selecting and configuring radio access technologies (RATs) that lead to either unnecessary power consumption or insufficient data throughput, resulting in a suboptimal user experience due to disparities in performance and power profiles between different RATs like 5G NR and 4G LTE.
Innovation Solution
A UE is equipped with a RAT operational control scheme that dynamically manages the enablement and disablement of 5G NR and 4G LTE RATs based on display activity, throughput thresholds, battery saving modes, data traffic patterns, and adaptive scaling, ensuring optimal power usage and throughput for various applications.

Engineering Contradiction Analysis
1Productivity
If mmWave 5G NR RAT is used to provide higher uplink and downlink throughputs, then data throughput is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic RAT selection and configuration that adapts to changing conditions. The system continuously monitors throughput requirements, power consumption levels, display activity state, and application needs to dynamically switch between 5G NR and 4G LTE RATs. This dynamic adaptation allows the system to optimize the balance between data throughput and power consumption in real-time based on actual operational conditions.
Solution Approach 2:
The system changes operational parameters by selectively enabling or disabling specific RATs (5G NR or 4G LTE) based on monitored conditions. When high throughput is required and power is available, 5G NR is enabled; when power conservation is needed or throughput requirements are modest, the system switches to 4G LTE or disables 5G NR. This parameter change approach resolves the contradiction by adjusting which RAT is active based on the trade-off between throughput and power consumption.
2Use of energy by moving object
If RAT selection is ineffective, then unnecessary power consumption occurs, but if RAT configuration is ineffective, then insufficient data throughput results
Solution Approach 1:
The patent implements a feedback mechanism that continuously monitors multiple parameters including throughput metrics, power consumption levels, display activity state, application requirements, and network conditions. Based on this feedback, the system dynamically adjusts RAT selection and configuration decisions. This closed-loop feedback system ensures that RAT choices are continuously optimized to balance power consumption and data throughput, preventing both unnecessary power usage and insufficient throughput.
Solution Approach 2:
The system performs self-service by autonomously monitoring its own operational state and making intelligent RAT selection decisions without requiring manual intervention. The UE's processor automatically evaluates throughput requirements, power consumption patterns, and application needs to independently determine the optimal RAT configuration, enabling the system to serve itself in optimizing the power-throughput balance.
3Use of energy by moving object
If display is inactive and throughput requirements are low, then power consumption is reduced by disabling RAT, but if display is active, then data throughput must be maintained by keeping RAT enabled
Solution Approach 1:
The system dynamically adjusts RAT enablement status based on display activity state. When the display is inactive and throughput requirements are low, the system disables the RAT to conserve power. When the display becomes active, the system re-enables the RAT to ensure adequate data throughput. This dynamic response to display state changes allows the system to optimize the power-throughput balance according to actual user interaction conditions.

AI summary
A user equipment (UE) employing different radio access technologies (RATs) concurrently or successively provides the UE the opportunity to select a particular RAT to support an access service used by one or more software applications of the UE. A RAT operational control scheme provides for opportunistic enablement and disablement of a RAT and/or intra-RAT configuration so as to provide sufficient uplink and downlink throughput for supported software applications while reducing unnecessary power consumption by the UE, which often is battery powered.
