User Terminal Search Space Typing for CORESET Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current search space configurations in future radio communication systems, such as NR, lack detailed definitions for search space types, leading to increased communication traffic and degradation in communication throughput and frequency use efficiency.
Innovation Solution
A user terminal with a control section that determines the type of search space based on specific information in the search space configuration, and a receiving section that monitors a control resource set (CORESET) using the identified search space, enabling appropriate association between search spaces and CORESETs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If detailed definitions for search space types are not defined in current search space configurations, then the system maintains simplicity in configuration design, but communication traffic increases unnecessarily and communication throughput and frequency use efficiency degrade
Solution Approach 1:
The patent segments the search space configuration into multiple types (first type, second type, third type) based on different monitoring requirements. Each search space type is associated with specific CORESETs and has distinct monitoring parameters, allowing the system to optimize control channel monitoring efficiency without requiring overly complex overall configuration.
Solution Approach 2:
The patent applies local quality by configuring different search space types with different characteristics tailored to specific needs. For example, the first type of search space is configured with specific monitoring occasions and associations with first CORESETs, while the second type has different configurations associated with second CORESETs, allowing optimal local performance for different control information scenarios.
2Productivity
If appropriate search space configuration methods are not employed, then the system maintains ease of operation, but communication traffic increases unnecessarily and frequency use efficiency degrades
Solution Approach 1:
The patent changes key parameters of search space configurations by introducing type distinctions with different monitoring occasions, CORESET associations, and DCI format specifications. This allows the system to optimize frequency use efficiency by matching appropriate search space types to different traffic patterns and control information requirements, rather than using a single uniform configuration.
3Productivity
If search spaces are not properly associated with CORESETs, then the system maintains simplicity in association management, but communication efficiency and throughput degrade
Solution Approach 1:
The patent segments the association between search spaces and CORESETs by creating distinct association rules for different search space types. The first type of search space is associated with first CORESETs, the second type with second CORESETs, and the third type with third CORESETs, allowing efficient management of associations without requiring complex cross-referencing between all search spaces and all CORESETs.
