UE Bandwidth Part Switching for Low-Energy Wireless Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems do not effectively adapt bandwidth parts (BWP) based on the energy level of user equipment (UE), leading to inefficient power usage and potential gaps in coverage.
Innovation Solution
The UE dynamically adapts its active BWP by switching to a smaller bandwidth size or default BWP when its energy level falls below a threshold, reducing power consumption and processing overhead, and communicates this change to the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UE uses a larger bandwidth size for active BWP, then the data transmission rate and network coverage are improved, but the power consumption and processing overhead increase
Solution Approach 1:
The patent implements dynamic BWP switching that adapts the bandwidth size based on real-time energy level conditions. The UE monitors its energy level and dynamically switches between different BWP configurations (first BWP with larger bandwidth for high data rate, second BWP with smaller bandwidth for low power consumption) according to whether the energy level meets a threshold condition, making the system flexible and adaptive to changing operational states
Solution Approach 2:
The patent changes the bandwidth parameter of the active BWP based on energy level conditions. When the energy level meets the threshold, the system uses a first BWP configuration with larger bandwidth for high-speed data transmission. When the energy level does not meet the threshold, the system switches to a second BWP configuration with smaller bandwidth to reduce power consumption, thereby optimizing performance based on energy availability
2Reliability
If the UE monitors more frequency resources in a larger BWP, then the network coverage and signal quality are improved, but the processing overhead and energy consumption increase
Solution Approach 1:
The patent dynamically adjusts the monitoring scope of frequency resources based on energy level conditions. When energy is sufficient, the UE monitors frequency resources across a larger BWP to ensure comprehensive network coverage and signal quality. When energy is limited, the UE reduces monitoring to a smaller BWP scope, thereby reducing processing overhead while maintaining essential coverage through selective monitoring
3Use of energy by moving object
If the UE operates with a default BWP, then the power consumption is reduced, but the data transmission capacity and network performance decrease
Solution Approach 1:
The patent implements periodic switching between default BWP and active BWP based on energy level conditions. The UE does not permanently stay in default BWP mode but periodically switches to active BWP with larger bandwidth when energy conditions improve (energy level meets threshold), and switches back to default BWP when energy conditions deteriorate, creating a rhythmic adaptation pattern that balances power savings with performance needs

AI summary
This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for bandwidth part (BWP) dynamic adaptation in accordance with an energy level at a user equipment (UE). In some systems, the UE may implement techniques for power savings by operating according to a narrower BWP in accordance with an energy level at the UE. In some implementations, the UE may reduce the bandwidth size of the active BWP if the UE energy level satisfies a threshold. The UE may transmit signaling to the network indicating that the bandwidth size of the active BWP is reduced. Additionally, or alternatively, the UE may fall back to a default BWP if the UE energy level satisfies a threshold. For example, the UE may fall back to the default BWP prior to expiration of a timer configured to trigger the UE to fall back to the default BWP.
