MIB-Based CORESET Width Configuration for Reduced-Capability Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, terminals with reduced capabilities face challenges in accessing the system due to configuration settings that exceed their maximum transmission bandwidth, affecting the reception of essential system information.
Innovation Solution
A method for determining configuration information involves adjusting the frequency domain width of a first CORESET for terminals with reduced capabilities by using a modified MIB or signaling to ensure it is less than that of terminals with higher capabilities, allowing them to receive system information within their bandwidth limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the frequency domain width of CORESET is increased to accommodate more system information, then the information capacity is improved, but terminals with reduced capabilities cannot access the system due to exceeding their maximum transmission bandwidth
Solution Approach 1:
The patent segments the CORESET configuration into different versions: a first CORESET configuration for terminals with reduced capabilities and a second CORESET configuration for terminals with higher capabilities. This segmentation allows the system to provide tailored control resource sets that match different terminal bandwidth capabilities, enabling terminals with reduced capabilities to access system information without being blocked by configuration settings designed for higher-capability terminals.
2Adaptability or versatility
If the MIB structure is modified to include separate configuration fields for different terminal capabilities, then the adaptability is improved, but the signaling complexity increases
Solution Approach 1:
The patent implements a universal MIB structure that serves multiple terminal types through a single configuration field. The same MIB field is used to indicate both the first CORESET configuration for terminals with reduced capabilities and the second CORESET configuration for terminals with higher capabilities. This multi-functional approach allows the system to adapt to different terminal capabilities without requiring separate MIB structures or additional signaling fields, thereby maintaining simplicity while achieving versatility.

AI summary
A method for determining configuration information, includes: a first terminal receiving a master information block (MIB) and; the first terminal determining configuration information of a first control resource set based on the MIB, the configuration information of the first control resource set including a frequency domain width of the first control resource set, the frequency domain width of the first control resource set being less than a frequency domain width of a second control resource set of a second terminal, and the frequency domain width of the second control resource set being determined based on the MIB.
