Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing PDCCH blind detection capability of user equipment (UE) is limited in scenarios involving multiple transmission/reception points (TRPs), leading to reduced scheduling flexibility for terminals.
Innovation Solution
The UE is configured to perform blind detection at PDCCH candidate locations based on first configuration information, allowing for a larger quantity of detections per CORESET group, optimizing the detection process to improve scheduling flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal performs blind detection based on single-cell blind detection capability, then the detection process is simple, but the scheduling flexibility is reduced when multiple TRPs schedule the terminal
Solution Approach 1:
The patent divides the blind detection process into separate CORESET groups, where each group corresponds to a specific TRP. The terminal performs blind detection independently for each CORESET group, allowing the network to allocate different detection quantities to different TRPs. This segmentation enables flexible scheduling while maintaining manageable detection complexity through structured organization.
Solution Approach 2:
The patent introduces dynamic configuration of blind detection quantities for each CORESET group based on network conditions. The network can dynamically adjust the detection quantity for each TRP-based CORESET group according to scheduling needs, transforming a static detection capability into a dynamic, adaptable system that optimizes resource utilization.
2Adaptability or versatility
If the terminal blindly detects PDCCH for all CORESETs in the target cell for a maximum quantity of times, then the detection coverage is comprehensive, but the scheduling flexibility for multi-TRP scenarios is limited
Solution Approach 1:
The patent applies different blind detection quantities to different CORESET groups based on their associated TRPs. Instead of uniform detection across all CORESETs, each CORESET group receives a customized detection quantity according to local scheduling requirements, enabling optimized resource allocation and flexible multi-TRP scheduling.
Solution Approach 2:
The patent introduces a new dimension of organization by grouping CORESETs according to their associated TRPs. This dimensional reorganization allows the system to manage detection quantities at the CORESET group level rather than at the individual CORESET level, providing finer-grained control and enhanced scheduling flexibility.

AI summary
This application provides a communication method and a communications apparatus. A terminal may perform, based on first configuration information for a maximum of a first quantity of times, blind detection at PDCCH candidate locations configured by a network device for a first CORESET group. In comparison with a solution, in the conventional technology, in which the terminal blindly detects a PDCCH for all CORESETs in a target cell for a maximum of the first quantity of times, blind detection is performed for a CORESET corresponding to each TRP for a larger quantity of times. Therefore, scheduling flexibility can be improved.
