Reduced Capability CORESET Configuration for Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in resource utilization due to the standard control resource set (CORESET) configurations, which can strain the processing and bandwidth capabilities of reduced-capability user equipment (UEs), leading to suboptimal communication efficiency and resource consumption.
Innovation Solution
Implementing a reduced capability CORESET configuration that is a sub-region of the standard CORESET, allowing for multiplexing or overlapping with non-reduced-capability CORESET regions, using distinct control channel candidates and radio network temporary identifiers to differentiate and optimize resource allocation for reduced-capability UEs.

Engineering Contradiction Analysis
1Reliability
If a standard CORESET configuration is used for all UEs, then non-reduced-capability UEs can efficiently utilize control resources, but reduced-capability UEs experience excessive processing load and bandwidth consumption
Solution Approach 1:
The CORESET region is segmented into multiple sub-regions, with a first sub-region allocated for reduced-capability UEs and a second sub-region for non-reduced-capability UEs. This segmentation allows each UE type to access control resources appropriate to its capabilities, reducing processing load and bandwidth consumption for reduced-capability UEs while maintaining efficient resource utilization for non-reduced-capability UEs.
2Use of energy by moving object
If a reduced capability CORESET configuration is implemented for reduced-capability UEs, then resource consumption is reduced, but system complexity increases due to multiplexing and overlapping configurations
Solution Approach 1:
The CORESET configuration is designed to serve multiple UE types simultaneously through multi-functionality. The same CORESET structure supports both reduced-capability UEs (in the first sub-region) and non-reduced-capability UEs (in the second sub-region), allowing a single configuration framework to handle diverse UE capabilities without requiring entirely separate systems.
Solution Approach 2:
The patent introduces a spatial dimension to CORESET allocation by dividing the control resource region into multiple sub-regions. This dimensional approach allows reduced-capability UEs and non-reduced-capability UEs to be differentiated by their allocated sub-region rather than requiring completely separate configuration structures, thereby reducing overall system complexity.
3Productivity
If distinct control channel candidates are used for reduced-capability UEs, then resource allocation is optimized, but backward compatibility with non-reduced-capability UEs may be compromised
Solution Approach 1:
Different control channel candidate configurations are applied locally to different UE types. Reduced-capability UEs receive control channel candidates configured for their specific capabilities in the first sub-region, while non-reduced-capability UEs receive appropriately configured candidates in the second sub-region. This local differentiation optimizes resource allocation for each UE type while maintaining overall system compatibility.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, based at least in part on the UE being a reduced-capability UE, control information on a reduced capability control resource set (CORESET) at least partially in a reduced capability region of a CORESET region, wherein the reduced capability CORESET is associated with a reduced configuration relative to a CORESET for a non-reduced-capability UE; and communicate in accordance with the control information. Numerous other aspects are provided.
