Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently configuring control resource sets (CORESETs) for user equipment (UE) in next-generation radio access technologies, particularly in managing resource allocation across sub-bands to enhance communication capacity and reliability, especially for massive Machine Type Communications (mMTC) and Ultra-Reliable and Low Latency Communications (URLLC).
Innovation Solution
A method for configuring CORESETs by establishing a reference point for frequency domain resource allocation, allowing for efficient allocation of minimum resource blocks within each resource group, thereby optimizing resource usage and improving communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional resource allocation methods are used for CORESET configuration, then system compatibility is maintained, but resource allocation efficiency and communication capacity are insufficient
Solution Approach 1:
The patent changes the reference point parameter for frequency domain resource allocation from a traditional fixed point to the starting point of each sub-band. This parameter change enables more flexible resource allocation within sub-bands, improving resource utilization efficiency and communication capacity while maintaining system compatibility through standardized configuration methods
2Quantity of substance
If resource allocation is optimized for high capacity, then communication capacity increases, but resource allocation flexibility and adaptability decrease
Solution Approach 1:
The patent segments the frequency domain resources into sub-bands and establishes reference points at the starting points of each sub-band. This segmentation allows independent resource allocation within each sub-band, simultaneously increasing communication capacity through efficient resource utilization and maintaining flexibility through localized allocation adjustments
3Reliability
If CORESET configuration uses fixed reference points, then configuration simplicity is maintained, but resource allocation efficiency and communication reliability are insufficient
Solution Approach 1:
The patent modifies the reference point parameter location to sub-band starting points, which improves communication reliability by enabling more precise resource allocation and reducing interference. The configuration remains relatively simple as it follows standardized procedures with clearly defined reference point rules
