Inter-RAT Switching Based on Power Consumption Metrics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly those using new radio (NR) technologies, face challenges in optimizing power consumption across different radio access technologies (RATs) and frequencies, leading to inefficient resource allocation and increased energy usage, especially with the introduction of power-hungry millimeter-wave (mmW) systems.
Innovation Solution
Implementing a method for inter-RAT resource switching based on power consumption metrics, where user equipment (UE) signals its power consumption levels and takes action to switch between different RAT resources, such as switching from mmW to LTE when battery life falls below a threshold, or switching between mmW bands, to optimize power usage.

Engineering Contradiction Analysis
1Speed
If millimeter-wave (mmW) systems are deployed to provide high data-rate communications, then communication speed and data rate are improved, but power consumption increases significantly
Solution Approach 1:
The patent implements dynamic RAT and band switching that adapts to changing power consumption conditions. The UE monitors its power state and dynamically transitions between mmW and non-mmW RATs, and between different mmW bands, to optimize the trade-off between data rate and power consumption based on real-time conditions
Solution Approach 2:
The patent changes operational parameters by switching between different RAT types (mmW vs. non-mmW) and different frequency bands. This parameter change allows the system to select operating modes with appropriate power consumption characteristics while maintaining necessary communication performance
2Duration of action of moving object
If the UE switches to lower power consumption RATs or bands, then power consumption is reduced and battery life is extended, but data rate may be compromised
Solution Approach 1:
The system dynamically adjusts RAT and band selection based on monitored power consumption conditions. When power levels are sufficient, the UE operates on high-performance mmW bands; when power consumption becomes critical, the UE dynamically switches to more energy-efficient configurations, creating an adaptive balance between battery life and data rate
Solution Approach 2:
The UE implements feedback mechanisms by monitoring its own power consumption state and using this information to make intelligent switching decisions. The system continuously assesses power conditions and adjusts RAT/band selection accordingly, ensuring that battery life is extended without completely sacrificing communication performance
3Use of energy by moving object
If inter-RAT and inter-band switching is implemented to optimize power consumption, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal switching framework that handles multiple RAT types (mmW, non-mmW) and multiple frequency bands through a unified decision-making process. This multi-functional approach consolidates what could be separate complex systems into a single integrated mechanism that manages power optimization across all RATs and bands

AI summary
Certain aspects of the present disclosure relate to methods and apparatus for inter-RAT resource switching based on power consumption using communications systems operating according to, for example, new radio (NR) technologies. For example, a method may generally include signaling at least one power consumption metric of the UE for communicating in at least first and second radio access technologies (RAT) resources, and taking action to switch to communicate via the first RAT resource, the second RAT resource, or both, based on the at least one power consumption metric.
