CSI Processing Resource Reallocation for Cell and BWP Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communications systems, resources used for CSI processing in user equipment (UE) are wasted and underutilized due to the UE being unable to perform measurements on multiple reference signal resources simultaneously, leading to inefficiencies when cells are deactivated or bandwidth parts are switched.
Innovation Solution
The UE processes target resources and CSI processing units using different processing manners based on actual requirements, allowing it to dynamically allocate resources for optimal utilization during measurement processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE allocates a CSI processing unit to a reference signal resource for measurement, then the measurement process can be performed accurately, but the CSI processing unit cannot be used for other reference signal resources, causing resource waste
Solution Approach 1:
The patent implements dynamic allocation of CSI processing units where the binding between CSI processing units and reference signal resources is not fixed. When a cell is deactivated or BWP is switched, the system dynamically releases the binding relationship, allowing the same CSI processing unit to be reallocated to different reference signal resources, thus improving resource utilization while maintaining measurement accuracy when needed
Solution Approach 2:
The patent makes CSI processing units universal by enabling them to serve multiple reference signal resources sequentially rather than being dedicated to a single resource. The same CSI processing unit can be allocated to different reference signal resources at different times, allowing one component to perform multiple functions and reducing overall resource requirements
2Measurement precision
If the UE performs measurement process on a reference signal resource, then accurate CSI can be obtained, but other resources related to this measurement process cannot be used in other processes, reducing overall resource utilization
Solution Approach 1:
The patent implements dynamic resource allocation where measurement resources are not permanently occupied during measurement processes. When measurements are complete or when cells/BWP change, resources are released back to the pool for reallocation, enabling continuous productivity improvement while maintaining measurement capabilities when required
Solution Approach 2:
The patent ensures continuous useful action by rapidly releasing measurement resources after use and reallocating them to new measurement tasks or other system functions. This minimizes idle time and ensures that resources continuously perform useful work, whether in measurement or other processes, maximizing overall productivity

AI summary
A method for processing a CSI processing unit, a resource processing method, an apparatus, and a system are disclosed and related to communications field. A method includes: UE receives first signaling from a base station, the first signaling is used to instruct to deactivate a first cell that provides a service for the UE, or used to instruct the UE to switch from a source BWP to a target BWP; when target information satisfies a preset condition, the UE processes a first CSI processing unit by using a first processing manner corresponding to the target information, the target information includes at least the first signaling, the first CSI processing unit is a CSI processing unit for measuring a first downlink reference signal resource which is a downlink reference signal resource in the first cell or the source BWP. Embodiments of this disclosure are applied to resource processing by the UE.
