AI Technical Summary

Technical Problem

UAVs and ground user equipment may not efficiently perform cell search due to non-optimized sky coverage by network nodes, leading to inefficient communication and increased power consumption.

Method used

A network node transmits different bitmap information representing whether to transmit a synchronization signal block, varying according to the relative position of user equipment with respect to the network node, allowing user equipment to efficiently perform cell search and reduce power consumption.

Benefits of technology

The proposed solution enables efficient cell search for both UAVs and ground user equipment, optimizing communication efficiency and reducing power consumption by tailoring synchronization signal block transmission based on equipment location.

Abstract

A network node according to one aspect manages cells in a mobile communication system. The network node has a transmission unit that transmits multiple pieces of bit map information each indicating whether or not to transmit a synchronization signal block within one cycle period of a predetermined frequency, the bit map information being different according to the position of user equipment relative to the network node.
