Title:
SINGLE FREQUENCY NETWORK CELL CONFIGURATION USING HAPS
Document Type and Number:
WIPO Patent Application WO/2020/013176
Kind Code:
A1
Abstract:
The present invention suppresses a deterioration in communication quality, which is caused by frequently-occurring handovers at the cell edges of a plurality of sector cells formed by a communication relay device that is movable in the air. The communication relay device, which wirelessly communicates with a terminal device, is provided with a relay communication station mounted in a floating body that is movable in the air by an autonomous control or a control from the outside. The relay communication station forms a plurality of sector cells so as to be able to wirelessly communicate with the terminal device. The plurality of sector cells include a plurality of single frequency network (SFN)-type sector cells in which identical data is transmitted in a state of being temporally synchronized at an identical frequency.
