Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing resource allocation for control channels, particularly in next-generation radio access technologies like NR, which require enhanced mobile broadband, massive MTC, and Ultra-Reliable and Low Latency Communication (URLLC), leading to inefficiencies in resource utilization and increased latency.
Innovation Solution
The introduction of a method for monitoring physical control channels (PDCCH) based on CORESET settings, where the duration on the time axis is composed of 4 or more symbols, optimizing resource allocation and enhancing communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the CORESET duration is extended to 4 or more symbols, then resource allocation efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the control channel monitoring process by introducing specific monitoring occasions and associating multiple search space sets with a single CORESET. This segmentation allows the system to efficiently utilize extended CORESET duration without proportionally increasing device complexity, as the segmentation enables structured and manageable resource allocation.
Solution Approach 2:
The patent implements dynamic configurations for CORESET monitoring by allowing flexible association between search space sets and CORESETs, and by defining monitoring occasions that can be dynamically adjusted. This dynamic approach enables the system to adapt resource allocation to varying traffic conditions while maintaining manageable device complexity through standardized procedures.
2Productivity
If resource allocation is optimized for next-generation technologies, then communication efficiency is improved, but system complexity increases
Solution Approach 1:
The patent creates a universal framework that supports multiple next-generation communication technologies (eMBB, massive MTC, URLLC) through a common CORESET monitoring mechanism. By designing a multi-functional system where search space sets can be associated with CORESETs in flexible configurations, the patent achieves improved communication efficiency across different service types without requiring separate complex systems for each technology.
Solution Approach 2:
The patent optimizes communication efficiency by enabling flexible parameter configurations including variable CORESET durations (4 or more symbols), adjustable monitoring occasions, and configurable search space set associations. These parameter changes allow the system to adapt to different service requirements while maintaining a unified structure that manages overall system complexity.
