Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The behavior of User Equipment (UE) in evaluating execution conditions during Conditional Primary Secondary Cell Group Cell Addition/Change (CPAC) is not clearly defined, leading to ambiguity in subsequent CPAC executions.
Innovation Solution
A method and apparatus for conditional configuration information processing in UE, where during CPAC execution, the UE continues or stops evaluating execution conditions associated with candidate cells in specified conditional configuration information, clarifying the evaluation behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the UE releases all stored conditional reconfiguration information after CPAC succeeds, then the system complexity is reduced and power consumption is lowered, but the capability for subsequent CPAC executions is lost
Solution Approach 1:
The patent applies local quality by differentiating the treatment of different conditional configuration information types. Specifically, CHO configuration information is released after CPAC success, while subsequent CPAC configuration information is retained. This selective retention/release strategy optimizes power consumption for operations that are no longer needed while preserving capabilities for future operations that may be beneficial.
Solution Approach 2:
The patent segments conditional configuration information into distinct types (CHO configuration information and subsequent CPAC configuration information) with different retention policies. This segmentation allows the system to manage different configuration data independently, releasing only what is unnecessary while keeping what may be useful for future cell changes, thereby balancing power savings with operational flexibility.
2Reliability
If the UE continues to evaluate execution conditions for all candidate cells during CPAC, then the reliability of cell selection is improved, but the processing complexity and time consumption increase
Solution Approach 1:
The patent applies preliminary action by having the UE evaluate execution conditions for candidate cells in advance and store the results in conditional reconfiguration information. When CPAC is executed, the UE can directly use these pre-evaluated results rather than performing new evaluations, thereby reducing real-time processing complexity while maintaining reliable cell selection based on thorough advance assessment.
3Quantity of substance
If the UE releases CHO configuration information after CPAC success, then the memory usage is reduced and power consumption is lowered, but the capability for conditional handover is lost
Solution Approach 1:
The patent applies local quality by implementing differentiated retention policies for different types of configuration information. CHO configuration information is released after CPAC success since it serves its purpose, while subsequent CPAC configuration information is retained to preserve future cell change capabilities. This selective approach optimizes memory usage and power consumption without completely sacrificing operational flexibility.

AI summary
This application provides a conditional configuration information processing method and apparatus, and a terminal. The conditional configuration information processing method includes: during execution of Conditional Primary Secondary Cell Group Cell Addition/Change (CPAC), a terminal performs a first operation. The first operation includes at least one of the following: continuing to evaluate or stopping evaluating an execution condition associated with a candidate cell included in first conditional configuration information; or continuing to evaluate or stopping evaluating an execution condition associated with a candidate cell included in second conditional configuration information. The first conditional configuration information includes CPAC configuration information or subsequent CPAC configuration information. The second conditional configuration information includes Conditional Handover (CHO) configuration information or CHO configuration information with CPAC configuration information.
