BWP Switching via Time Unit Boundary Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in efficiently switching between Bandwidth Parts (BWPs) with different numerologies, which are essential for providing diverse services and resource sharing, as existing methods lack effective mechanisms for aligning switching with time unit boundaries and monitoring periodicity.
Innovation Solution
The method involves a User Equipment (UE) and network equipment that receive and transmit control signaling to switch between BWPs with different numerologies, aligning with a time unit boundary associated with the scheduling BWP, and monitoring periodicity to ensure seamless transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If BWP switching is implemented without aligning with time unit boundaries, then switching flexibility is improved, but system reliability and timing synchronization deteriorate
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple BWP sets with different numerologies and establishing switching rules aligned with time unit boundaries before actual switching occurs. The network equipment configures the UE with multiple BWP sets in advance, and switching only occurs at predetermined time boundaries, ensuring both flexibility and synchronization reliability.
2Speed
If BWP switching occurs at arbitrary time points, then response speed is improved, but resource allocation efficiency and monitoring periodicity alignment worsen
Solution Approach 1:
The patent implements periodic action by aligning BWP switching with periodic time unit boundaries and monitoring periodicity. Switching occurs at regular intervals defined by the time unit boundary, ensuring that resource allocation maintains efficiency while still providing timely switching capability. The monitoring periodicity is synchronized with these boundaries to maintain efficient resource utilization.
3Adaptability or versatility
If multiple BWP sets with different numerologies are configured, then service diversity and resource sharing are improved, but device complexity and configuration management worsen
Solution Approach 1:
The patent applies segmentation by dividing BWPs into multiple organized sets, each with specific numerology characteristics. Instead of managing all BWPs individually, the UE handles multiple organized sets, reducing configuration management complexity while maintaining support for diverse services through different numerologies within each set.

AI summary
A user equipment (UE) receives control signaling in a scheduling bandwidth part (BWP). The control signaling indicates switching from a first active BWP to a second active BWP or switching from a first active BWP pair to a second active BWP pair for the UE. The control signaling aligns with a time unit boundary, such as a slot boundary, that is associated with the scheduling BWP. In the event that a scheduled BWP for a UE has a different numerology than a scheduling BWP that is currently active for the UE, the UE could switch from the scheduling BWP to the scheduled BWP based on a control signaling monitoring periodicity of the scheduled BWP.
