AI Technical Summary

Technical Problem

Non-terrestrial networks face challenges in improving mobility performance and reducing user equipment energy consumption, particularly in satellite communication systems where synchronization signal block periodicity changes affect coverage and power consumption.

Method used

A synchronization signal indicator is transmitted by network nodes in non-terrestrial networks to inform user equipment about upcoming changes in synchronization signal transmission, allowing UEs to determine cell camping or access strategies, thereby reducing unnecessary measurements and power consumption.

Benefits of technology

This approach enhances mobility performance and reduces network traffic load by enabling UEs to make informed decisions about cell changes without acquiring downlink synchronization, thus optimizing energy consumption and network efficiency.

Abstract

An arrangement for non-terrestrial communication networks, where a network node providing a cell transmits an indicator of upcoming change in the transmission of synchronization signals to a user equipment. Based on the received indicator the user equipment may determine whether to change the cell or to camp in the current cell. Similar indicator may be used during cell change procedure when determining whether to access the cell found in the cell search procedure or to re-initiate the cell search procedure for finding another cell.
