Cross-Carrier Blind Detection Configuration for Per-Cell Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cross-carrier scheduling configurations in mobile communication systems limit terminals to the same number of blind detections across all scheduling and scheduled cells, failing to accommodate different requirements for each cell.
Innovation Solution
Implement a method and apparatus that allow terminals to determine different numbers of blind detections for each cell by utilizing configuration information from both the scheduling and scheduled cells, enabling flexible blind detection based on UE capability and AS version information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal adopts the same number of blind detections for all scheduling cells and scheduled cells, then the configuration is simple and uniform, but it cannot accommodate different requirements for different cells
Solution Approach 1:
The patent applies local quality by allowing different blind detection configurations for different cells. Specifically, the terminal determines the number of blind detections for a scheduled cell based on configuration information from both the scheduling cell and the scheduled cell itself, enabling each cell to have customized blind detection parameters according to its specific requirements rather than forcing a uniform configuration across all cells.
2Adaptability or versatility
If different cells have different number of blind detections, then the configuration is flexible and adaptive, but it increases the complexity of blind detection determination
Solution Approach 1:
The patent segments the blind detection configuration into two parts: configuration information from the scheduling cell and configuration information from the scheduled cell. This segmentation allows the terminal to separately process and combine these configuration elements, managing the complexity by breaking down the determination process into manageable components rather than handling all cell-specific parameters in a single undifferentiated process.
Solution Approach 2:
The patent applies preliminary action by having the network pre-configure blind detection parameters for each cell before the terminal performs blind detections. The configuration information is provided in advance through RRC signaling, allowing the terminal to prepare and store these parameters for efficient retrieval and application during actual blind detection operations, rather than calculating them in real-time.
3Productivity
If uniform blind detection configuration is used across all cells, then the implementation is straightforward, but it fails to optimize performance for specific cell conditions
Solution Approach 1:
The patent enables local optimization by allowing each scheduled cell to have its own blind detection configuration tailored to its specific conditions. The terminal determines the number of blind detections by combining configuration information from the scheduling cell with cell-specific configuration information, ensuring that each cell's blind detection parameters are optimized for its local requirements while maintaining a systematic approach to implementation.

AI summary
Embodiments of the present application provide a method, an apparatus and a terminal for determining the number of times of blind detections, which includes: blind-detecting, by a terminal, a downlink control channel in a first search space of a first cell, where the downlink control channel is configured to schedule a second cell, and the number of times of blind detections of the downlink control channel are determined based on configuration information of a second search space of the second cell and/or configuration information of the first search space of the first cell.
