Dynamic Bandwidth Part Switching for 5G Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G communication systems face challenges in effectively managing bandwidth parts (BWP) in wireless communication systems, particularly in NR mobile communication systems, where efficient bandwidth allocation and switching are necessary to support diverse user equipment (UE) capabilities and reduce power consumption.
Innovation Solution
A method is proposed where a UE receives initial BWP configuration information, performs random access, and switches to a second BWP based on instruction messages from a node B, allowing for dynamic bandwidth allocation and reduction of power consumption by activating specific BWPs, enabling efficient handovers and frequency measurement reporting.

1Productivity
If multiple bandwidth parts (BWPs) are configured and dynamically switched based on UE capabilities and traffic requirements, then system efficiency and power consumption are improved, but device complexity and control signaling overhead increase
Solution Approach 1:
The patent implements dynamic BWP switching where the UE can transition between different bandwidth parts based on real-time traffic requirements and capability matching. The system dynamically selects appropriate BWPs from a configured set, adjusting the active bandwidth according to current network conditions and UE capabilities, thereby optimizing system efficiency without requiring static pre-configuration for all scenarios
Solution Approach 2:
The patent divides the total system bandwidth into multiple distinct bandwidth parts (BWPs), each with specific characteristics suited for different UE capabilities and service types. This segmentation allows the system to allocate appropriate bandwidth segments to different UEs based on their requirements, improving overall system efficiency while managing complexity through structured division of the frequency spectrum

If multiple bandwidth parts (BWPs) are configured and dynamically switched based on UE capabilities and traffic requirements, then power consumption is reduced, but control signaling overhead increases
Solution Approach 1:
The patent implements dynamic BWP switching where the UE can transition between different bandwidth parts based on real-time traffic requirements and capability matching. The system dynamically selects appropriate BWPs from a configured set, adjusting the active bandwidth according to current network conditions and UE capabilities, thereby optimizing system efficiency without requiring static pre-configuration for all scenarios
Solution Approach 2:
The patent enables the UE to autonomously determine its capability matching status and trigger BWP switching based on pre-configured criteria. The UE can self-assess whether current traffic requirements match the active BWP characteristics and initiate switching operations without continuous network control signaling, thereby reducing overhead while maintaining power optimization benefits
