Repeater SSB Migration Signaling Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in repeater device migration, leading to increased overhead signaling and power consumption due to redundant transmission of synchronization signal blocks (SSBs) when a repeater device handovers between cells.
Innovation Solution
A method where a network entity receives signal measurements from a repeater device and adjusts SSB transmissions by indicating to activate or deactivate SSBs at the target cell, allowing for optimized SSB transmission during handover, reducing unnecessary SSB transmission and power consumption.

Engineering Contradiction Analysis
1Reliability
If SSB transmissions are performed at both source and target cells during repeater migration, then the repeater can maintain synchronization and connectivity during handover, but overhead signaling and power consumption increase due to redundant transmissions
Solution Approach 1:
The target cell transmits SSBs in advance before the repeater actually connects to it. This preliminary transmission allows the repeater to prepare for handover by receiving synchronization signals from the target cell before the actual migration occurs, ensuring smooth transition while avoiding redundant transmissions after the handover is complete
Solution Approach 2:
The system dynamically adjusts SSB transmission based on the repeater's migration state. SSB transmissions are activated at the target cell when migration is detected and deactivated after successful connection, optimizing the balance between maintaining synchronization reliability and reducing power consumption during different phases of the handover process
2Reliability
If SSB transmissions are performed at both source and target cells during repeater migration, then the repeater can maintain synchronization and connectivity during handover, but overhead signaling increases due to redundant transmissions

This preliminary transmission allows the repeater to prepare for handover by receiving synchronization signals from the target cell before the actual migration occurs, ensuring smooth transition while avoiding redundant transmissions after the handover is complete
Solution Approach 2:
The network entity monitors the repeater's connection status and uses this feedback to control SSB transmissions. When the repeater successfully connects to the target cell, the network entity deactivates SSB transmissions at the source cell, preventing redundant signaling while ensuring synchronization is maintained throughout the migration process

AI summary
Methods, systems, and devices for wireless communication are described. The method may include a first network entity receiving, from a repeater device, a report that indicates signal measurements associated with a first cell and transmitting, based at least in part on the report, a first signal that indicates to adjust transmission of synchronization signal blocks (SSB) by a second network entity using the first cell. Further, the method may include transmitting, based at least in part on the first signal, a second signal that indicates to perform a handover operation for the repeater device from a second cell to the first cell.
