Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Terminal devices struggle to distinguish among different CPAC candidate cell configurations associated with multiple procedures such as CHO+CPAC, CPAC, and SACG, leading to confusion and inefficient network management.

Innovation Solution

The method involves transmitting distinct information elements for each CPAC candidate cell configuration, including different transmission manners, validity times, and indication information to differentiate between configurations associated with CHO+CPAC, CPAC, and SACG procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the network device configures multiple CPAC candidate cell configurations for different procedures (CHO+CPAC, CPAC, SACG), then the network management capability is improved, but the terminal device cannot distinguish among them causing confusion

Engineering Contradiction:

Improvenetwork management capabilityVSAvoidconfiguration distinction

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent segments the configuration information by introducing distinct information elements (CHO cell configuration, SCG configuration, SACG configuration) for different procedures. Each configuration type is transmitted through dedicated information elements, allowing the terminal device to clearly distinguish and manage multiple CPAC candidate cell configurations without confusion.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the network device transmits configuration information for multiple procedures, then the network management capability is improved, but the information structure becomes more complex

Engineering Contradiction:

Improvenetwork management capabilityVSAvoidinformation structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent resolves the complexity issue by organizing multiple configuration types into a hierarchical structure with different information elements at various levels. The CHO cell configuration, SCG configuration, and SACG configuration are structured in distinct layers with clear relationships, transforming the complex flat structure into an organized multi-dimensional hierarchy that is easier to manage and process.

AI summary

A method for wireless communication, a terminal device, and a network device are provided. The method includes the following. A terminal device receives first candidate cell configuration information sent by a network device, where the first candidate cell configuration information includes one or more of: a first conditional primary secondary cell (PSCell) addition/change (CPAC) candidate cell configuration associated with a first conditional handover (CHO) cell configuration, a second CPAC candidate cell configuration, and a third CPAC candidate cell configuration associated with selective activation of cell groups (SACG). Information for transmitting the first CPAC candidate cell configuration is first information, information for transmitting the second CPAC candidate cell configuration is second information, and information for transmitting the third CPAC candidate cell configuration is third information. At least two of the first information, the second information, and the third information are different information elements (IEs) within same information.
