Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the new generation of communication systems, efficiently switching between Bandwidth Parts (BWPs) is crucial for improving efficiency and reducing power consumption, but existing solutions lack optimization.
Innovation Solution
A method and apparatus for switching BWPs, where a terminal receives a power saving signal from a base station, determines a target BWP based on a setting rule, and switches the currently activated BWP to the target BWP, without requiring information for a designated BWP in the power saving signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the power saving signal includes information for representing a designated BWP, then the BWP switching accuracy is improved, but the power consumption increases and switching rate decreases
Solution Approach 1:
The patent extracts only the necessary information from the power saving signal - specifically the BWP switching indication - while removing detailed BWP configuration information. The terminal already has BWP configuration stored from previous setup, so only the switching trigger is needed in the power saving signal, reducing signal complexity and power consumption while maintaining switching accuracy.
Solution Approach 2:
The BWP configuration information is provided to the terminal in advance through system messages or dedicated signaling before the power saving signal is received. This preliminary action allows the terminal to have all necessary BWP parameters stored locally, eliminating the need to transmit detailed configuration data in the power saving signal itself.
2Measurement precision
If the power saving signal includes information for representing a designated BWP, then the BWP switching accuracy is improved, but the switching rate decreases
Solution Approach 1:
The patent extracts only the essential BWP switching indication from the power saving signal, removing detailed BWP configuration data. This reduction in signal information content decreases processing time and enables faster switching rates while maintaining accurate BWP switching through pre-configured parameters.
Solution Approach 2:
BWP configuration parameters are prepared and stored in the terminal beforehand through system messages or dedicated signaling. This preliminary preparation eliminates the need for real-time configuration processing during switching, thereby increasing the switching rate while preserving switching accuracy.
3Productivity
If the terminal autonomously determines the target BWP based on setting rules, then the switching rate is improved and power consumption is reduced, but the device complexity increases
Solution Approach 1:
The terminal autonomously determines the target BWP by applying setting rules locally without requiring base station intervention for each switching decision. This self-service approach reduces signaling overhead and base station processing burden, improving switching rate while the rule-based methodology keeps terminal complexity manageable.
Solution Approach 2:
The patent uses predefined setting rules that define specific parameters and conditions for BWP switching. By changing operational parameters from detailed signal processing to rule-based decision making, the system achieves faster switching with controlled complexity through structured parameter comparisons.
4Use of energy by moving object
If the terminal autonomously determines the target BWP based on setting rules, then the power consumption is reduced, but the device complexity increases
Solution Approach 1:
The terminal performs autonomous BWP determination using locally stored setting rules, eliminating the need for continuous base station communication and detailed signal processing. This self-service mechanism reduces power consumption by minimizing active processing and transmission, while the rule-based approach maintains acceptable device complexity.
Solution Approach 2:
The system transitions from complex real-time signal analysis to simpler parameter-based rule evaluation. By changing the determination method to compare predefined parameters against setting rules, the terminal achieves lower power consumption while maintaining manageable complexity through structured decision logic.

AI summary
A method for switching a bandwidth part (BWP) is performed by a terminal. A base station configures at least one BWP for the terminal. The method includes receiving a power saving signal transmitted by the base station, in which the power saving signal is configured to instruct the terminal to perform a BWP switching; determining, based on a setting rule, a target BWP for switching, in which the power saving signal does not include information for representing a designated BWP, and the setting rule is transmitted by the base station to the terminal through a system message or a dedicated signaling; and switching a currently activated BWP to the target BWP.
