Serving Cell Measurement Objects for Active BWP SSB Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing serving cell measurement objects associated with active bandwidth parts (BWPs), particularly in determining synchronization signal block (SSB) frequencies, which affects the performance of user equipment (UE) in wireless networks.
Innovation Solution
The system configures measurement objects based on an active BWP of the UE, allowing for accurate determination of serving cell measurement objects by indicating SSB frequencies within the active BWP, enhancing communication efficiency.

1Measurement precision
If measurement objects are configured without considering active BWP, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The network entity pre-configures multiple measurement objects corresponding to different BWPs before the UE switches between them. When a BWP switch occurs, the UE can immediately use the pre-configured measurement object associated with the new active BWP, avoiding measurement delays and maintaining measurement accuracy without requiring complex real-time reconfiguration mechanisms.
Solution Approach 2:
The measurement object configuration is made dynamic by associating different measurement objects with different BWPs. The UE dynamically selects the appropriate measurement object based on the currently active BWP, allowing the measurement configuration to adapt automatically to BWP changes while maintaining a relatively simple overall structure through standardized association rules.
2Productivity
If measurement objects are dynamically adjusted based on active BWP, then measurement precision improves, but device complexity increases
Solution Approach 1:
The measurement configuration is segmented into multiple independent measurement objects, each associated with a specific BWP. This segmentation allows the network to optimize measurements for each BWP independently while maintaining overall system efficiency. The UE manages multiple simplified measurement objects rather than one complex dynamic configuration, reducing processing complexity while improving measurement relevance and network performance.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a configuration that indicates one or more measurement objects, wherein a measurement object of the one or more measurement objects indicates a synchronization signal block (SSB) frequency of a configured bandwidth part (BWP). The UE may determine, from the one or more measurement objects, a serving cell measurement object based at least in part on an active BWP of the UE, wherein the serving cell measurement object is associated with an SSB frequency in the active BWP. Numerous other aspects are described.
