Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing multiple concurrent service transmissions due to BWP switching delays, which impact user experience and restrict service transmission capabilities.

Implementing an enhanced BWP indicator field in DCI formats to allow simultaneous activation of multiple frequency resources, enabling dynamic switching and coordination of concurrent services without delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional single BWP activation is used, then device complexity is reduced, but service transmission capability is restricted and switching delays increase
Solution Approach 1:
The frequency resources are segmented into multiple Bandwidth Parts (BWPs), each capable of being independently activated or deactivated. The frequency resource indicator field is divided into multiple bits, where each bit corresponds to a specific BWP, allowing selective activation of individual BWPs based on service requirements.
Solution Approach 2:
The system enables dynamic activation and deactivation of multiple BWPs simultaneously through the enhanced frequency resource indicator field in DCI. This allows the network to adaptively allocate frequency resources based on real-time service needs, transitioning from static single-BWP operation to dynamic multi-BWP operation.
2Adaptability or versatility
If frequent BWP switching is performed, then service adaptation flexibility is improved, but switching delays increase and user experience deteriorates
Solution Approach 1:
Multiple BWPs are pre-configured and activated in advance before actual service transmission begins. The network can prepare multiple BWPs ahead of time, so when service adaptation is needed, the UE can switch between pre-prepared BWPs without waiting for configuration, reducing switching delays.
Solution Approach 2:
The patent combines multiple BWP activation/deactivation operations into a single DCI indication through the frequency resource indicator field. Instead of switching BWPs one by one, the system can simultaneously activate or deactivate multiple BWPs in a single operation, reducing the cumulative switching time and improving user experience.
3Productivity
If multiple frequency resources are activated simultaneously, then concurrent service transmission is enabled, but indication complexity increases
Solution Approach 1:
The indication field is segmented into multiple bits, with each bit representing a specific BWP. This segmentation allows the complex task of indicating multiple frequency resources to be broken down into simple binary decisions (activate/deactivate each BWP independently), making the indication mechanism manageable despite the increased number of resources.
Solution Approach 2:
The frequency resource indicator field serves multiple functions: it can indicate activation status of multiple BWPs, support both unicast and multicast services, and enable flexible resource allocation across different service types. This multi-functionality reduces the need for separate indication mechanisms for different service scenarios.
Data Source
AI summary
Example implementations include receiving, by a wireless communication device from a network, an indication indicating activation status of two or more frequency resources, wherein each bit in a frequency resource indicator field of the indication maps to a corresponding one of the two or more frequency resources. In response to receiving the indication, the wireless communication device communicates with the network data using at least one of the two or more frequency resources.
