Wireless Resource Switching with Group-Based Activation Delays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems experience delays in switching between active wireless resources due to inconsistent handling of configuration parameters, leading to inefficiencies in bandwidth part (BWP) switching.
Innovation Solution
Determine a specific delay for activating a wireless resource based on whether it belongs to the same group as the deactivated resource, thereby maintaining at least some configuration parameters to reduce switching delays.

Engineering Contradiction Analysis
1Loss of time
If configuration parameters are maintained during BWP switching, then switching delay is reduced, but device complexity increases due to parameter management
Solution Approach 1:
The patent segments configuration parameters into two categories: common parameters that are maintained across BWP switches and specific parameters that are reconfigured. This segmentation allows the device to preserve common parameters (reducing switching delay) while only reconfiguring specific parameters (managing complexity), thereby resolving the contradiction between fast switching and manageable complexity.
Solution Approach 2:
The patent applies preliminary action by pre-configuring multiple BWP parameters in advance, including common parameters that can be reused. When switching occurs, the device activates pre-prepared configuration sets, significantly reducing the time required for parameter reconfiguration while maintaining organized parameter management structures.
2Productivity
If default delay is applied to all BWP activations, then device operation is simplified, but switching efficiency decreases
Solution Approach 1:
The patent implements dynamic delay determination where the activation delay is adjusted based on the relationship between source and target BWP groups. If BWPs belong to the same group, a shorter delay is applied; if different groups, a longer delay is used. This dynamic approach optimizes switching efficiency while maintaining manageable complexity through clear conditional logic.
Solution Approach 2:
The patent changes the delay parameter dynamically based on BWP group relationships. Instead of using a fixed default delay, the system adjusts the delay parameter according to whether the source and target BWPs are in the same group, thereby improving switching efficiency for intra-group transitions while maintaining stability for inter-group transitions.

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.
