Wireless Resource Switching with Group-Based Activation Delays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face delays in switching between wireless resources, such as bandwidth parts (BWPs), due to the need for maintaining configuration parameters, which can be inefficient and inconsistent across different operations.
Innovation Solution
Implementing a method to determine and apply a specific delay for activating a wireless resource based on whether the resource to be activated and deactivated belong to the same group, thereby reducing switching delays by accounting for shared configuration parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a default delay is applied for activating wireless resources, then the switching process is simplified, but the switching delay increases and becomes inconsistent across different operations
Solution Approach 1:
The patent changes the delay parameter dynamically based on whether the source and target wireless resources share configuration parameters. When resources share configuration parameters, a first (shorter) delay is applied; when they don't share parameters, a second (longer) delay is applied. This resolves the contradiction by making the delay adaptive rather than fixed, reducing overall switching delay while maintaining operational simplicity through automated determination.
2Loss of time
If configuration parameters are maintained during wireless resource switching, then switching delay is reduced, but the complexity of managing configuration parameters increases
Solution Approach 1:
The patent segments wireless resources into groups based on shared configuration parameters. By organizing resources this way, the system can quickly determine whether switching will require full reconfiguration or can leverage existing parameters, reducing switching delay while managing complexity through structured organization rather than ad-hoc parameter management.
Solution Approach 2:
The patent performs preliminary classification of wireless resources into groups with shared configuration parameters before switching occurs. This advance organization allows the system to immediately determine the appropriate delay and reconfiguration needs when switching is triggered, reducing actual switching delay while managing complexity through pre-established groupings.
3Speed
If wireless resources are switched without considering group membership, then the switching process is faster, but resource activation becomes inconsistent and inefficient
Solution Approach 1:
The patent dynamically adjusts the activation delay parameter based on group membership determination. When resources belong to the same group (sharing configuration parameters), a shorter delay is applied; when they belong to different groups, a longer delay is applied. This maintains high switching speed while ensuring consistent and reliable resource activation by adapting to the specific switching scenario.

AI summary
Wireless communications may comprise communications between a base station and a wireless device. Wireless resources, such as bandwidth parts, may be used for the wireless communications. Based on a determination to switch a wireless resource, another wireless resource may be activated within a time duration. The time duration may be based on whether the wireless resource to be activated and the wireless device to be switched are in a same group of wireless resources.
