Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In future radio communication systems, the determination of cell application timing and beam application timing during inter-cell mobility remains unclear, leading to potential deterioration of communication quality.
Innovation Solution
A terminal equipped with a receiving section to receive specific information and a control section to determine cell and beam application timings based on this information, enabling appropriate timing determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If inter-cell mobility is implemented with separate candidate cell configuration, then mobility flexibility is improved, but timing determination clarity deteriorates
Solution Approach 1:
The patent introduces specific information (timing indication) as an intermediary element that mediates between the mobility management function and the terminal device. This timing indication explicitly carries timing determination information from the network side to the terminal, resolving the ambiguity in timing determination while preserving the flexibility of separate candidate cell configuration for inter-cell mobility
2Device complexity
If cell application timing is not appropriately determined, then system complexity is reduced, but communication quality deteriorates
Solution Approach 1:
The patent enables the terminal device to autonomously determine cell application timing and beam application timing based on the received specific information. This self-service mechanism allows the terminal to independently resolve timing determination without requiring complex network-side control or additional signaling, thereby maintaining low system complexity while ensuring reliable communication quality through accurate timing
