Multi-Cell Scheduling Dormant Reference Cell Substitution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-cell scheduling mechanisms struggle to effectively manage dormant cells within a set of cells, leading to inefficiencies in power saving and scheduling processes.
Innovation Solution
The proposed solution involves a user equipment (UE) processor that determines a first reference cell and, if it is in dormant mode, identifies a second reference cell for blind decode counting and control channel element counting, ensuring seamless multi-cell scheduling even when dormant cells are present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a reference cell is configured as dormant for power saving, then energy consumption is reduced, but multi-cell scheduling operations cannot be performed on that cell
Solution Approach 1:
The patent segments the cell set into dormant cells and active cells, allowing the UE to perform scheduling operations only on active cells while maintaining dormant cells in a low-power state. This segmentation enables the system to achieve power saving goals without completely disabling scheduling capabilities across all cells.
Solution Approach 2:
The patent introduces a substitution mechanism where a second reference cell acts as an intermediary to replace the dormant first reference cell for scheduling operations. The UE can identify and use alternative reference cells from the active cell set, maintaining scheduling functionality through this intermediary approach while the original cell remains dormant.
2Measurement precision
If the UE performs blind decode counting and control channel element counting on dormant cells, then scheduling accuracy is maintained, but processing overhead increases
Solution Approach 1:
The patent extracts the counting operations from dormant cells and relocates them to active cells only. By taking out the reference cell identification and counting processes from the dormant cell set and performing them exclusively on active cells, the system maintains scheduling accuracy while significantly reducing processing overhead associated with dormant cell analysis.
3Use of energy by moving object
If the UE disregards dormant cells in multi-cell scheduling, then power saving is achieved, but scheduling flexibility is reduced
Solution Approach 1:
The patent implements a dynamic cell state management mechanism where cells can transition between dormant and active states. The UE is capable of dynamically identifying and adapting to changes in cell dormancy status, and can flexibly substitute reference cells based on current active cell availability. This dynamic approach maintains scheduling flexibility while achieving power saving benefits from dormant cells.

AI summary
Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for managing dormant cell(s) within a set of cells for multi-cell scheduling. For example, a UE can be configured to receive information associated with a set of cells for multi-cell scheduling and determine a first reference cell based on the received information. The UE is further configured to determine a second reference cell for performing one or more of blind decode counting and control channel element counting in response to determining that the first reference cell is in a dormant mode. The UE is further configured to perform the one or more of blind decode counting and control channel element counting using the second reference cell.
