Conditional Reestablishment for Wireless Link Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems experience significant latency during link reestablishment procedures, which can disrupt service continuity and efficiency.
Innovation Solution
Implementing a conditional reestablishment method that configures and evaluates execution conditions for candidate cells, allowing for proactive link reestablishment before failures occur, thereby reducing latency and ensuring service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional reestablishment procedure is used, then service continuity is maintained, but reestablishment latency is high
Solution Approach 1:
The patent applies preliminary action by pre-configuring conditional reestablishment parameters and identifying candidate cells before link failure occurs. The UE receives conditional reestablishment configuration information including candidate cell IDs and execution conditions, evaluates these conditions proactively, and prepares reestablishment resources in advance, enabling faster recovery when failure actually occurs.
2Reliability
If conditional reestablishment with multiple candidate cells is implemented, then reestablishment reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the reestablishment process into distinct components: candidate cell identification, condition evaluation, and execution triggers. Each candidate cell is independently configured with specific execution conditions, allowing the system to manage multiple reestablishment options through modular, organized configuration rather than monolithic complexity.

AI summary
Embodiments of the present disclosure relates to methods and apparatuses for conditional reestablishment and consecutive reestablishment. According to some embodiments of the present disclosure, a method includes: receiving, at a user equipment (UE), conditional reestablishment configuration information indicating a set of execution conditions for a set of candidate cells, wherein each candidate cell of the set of candidate cells is associated with at least one execution condition; and evaluating the set of execution conditions based on the conditional reestablishment configuration information. The UE may autonomously perform a reestablishment procedure in response to the condition is met. In addition, the UE can perform consecutive reestablishment based on the configuration.
