AI Technical Summary

Technical Problem

The challenge of reconfiguring a cell for a mobile IAB node without affecting the services of active terminals due to physical cell identifier (PCI) conflicts with surrounding cells during movement.

Method used

A method and system for cell reconfiguration that involves selecting a non-conflicting PCI for a mobile IAB node to create a new cell as a secondary or primary secondary cell, establishing a connection with the terminal, and releasing the original cell, using carrier aggregation or dual connectivity technologies.

Benefits of technology

Ensures continuous service for active terminals by creating a new cell without interrupting existing services during cell reconfiguration, addressing PCI conflicts and enabling seamless communication.
