TCI State Configuration for Multi-Mode Component Carriers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in 5G NR, there are challenges in configuring, activating, and indicating transmission configuration indicator (TCI) states for component carriers (CCs) operating in different modes, which can lead to issues such as RRC configuration mismatches and processing complexities due to variations in the number of TCI pools and modes used by different CCs.
Innovation Solution
The proposed solution involves defining rules and functions to handle the configuration, activation, and indication of TCI states across CCs, allowing for the use of a reference CC's TCI pool configuration to configure another CC operating in a different mode, thereby ensuring compliance with wireless communication technology specifications and reducing radio resource consumption and processing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different component carriers use different numbers of TCI pools based on their operating modes, then the system can adapt to various transmission scenarios, but it leads to RRC configuration mismatches and increased processing complexity
Solution Approach 1:
The patent applies universality by enabling a reference CC's TCI pool configuration to serve multiple purposes: it configures the reference CC itself and also serves as the basis for configuring other CCs operating in different modes. This multi-functional approach allows different CCs to share configuration resources, reducing overall system complexity while maintaining adaptability to various transmission scenarios.
Solution Approach 2:
The patent utilizes parameter changes by allowing dynamic selection of TCI pools based on the operating mode of each CC. Instead of requiring all CCs to have identical configurations, the system adjusts the number and selection of TCI pools according to mode-specific requirements, thereby reducing configuration complexity while preserving adaptability.
2Manufacturing precision
If each component carrier is configured with its own complete TCI pool configuration, then configuration accuracy is maintained, but radio resource consumption and processing complexity increase
Solution Approach 1:
The patent applies merging by combining the TCI pool configurations of multiple CCs into a single reference CC configuration. The reference CC's TCI pools are merged and reused across other CCs, eliminating redundant configuration transmissions and reducing radio resource consumption while maintaining configuration accuracy through systematic application rules.
Solution Approach 2:
The patent uses copying by creating TCI pool configurations for secondary CCs as copies or subsets of the reference CC's TCI pool configuration. Instead of transmitting entirely new configurations for each CC, the system copies and adapts the reference configuration, thereby reducing resource consumption while preserving necessary configuration accuracy.
3Adaptability or versatility
If the system supports multiple TCI pool configurations for different modes, then mode flexibility is improved, but processing complexity and configuration mismatches increase
Solution Approach 1:
The patent applies segmentation by dividing the TCI pool configuration into mode-specific segments. Each CC is assigned a specific number of TCI pools based on its operating mode (e.g., one-mode CCs receive a subset, multi-mode CCs receive additional pools). This segmented approach maintains mode flexibility while simplifying processing by providing clear, mode-appropriate configuration boundaries.
