Classification: CPC H | IPC H

Claim 0:
1. A wireless communication device configured to be mounted to a flying body to radiate a plurality of beams toward the ground, thereby forming a multi-cell to provide wireless communication services to a user terminal in the multi-cell, comprising:
a plurality of radio units including a first radio unit and a second radio unit; and
a control unit configured to control each of the plurality of radio units to form a cell, thereby forming the multi-cell,
wherein the control unit has:
a removal processing performing unit configured to, based on a first reception radio wave in which the first radio unit received a first transmission radio wave which includes a first signal transmitted by a first user terminal located in an area of a first cell formed by the first radio unit, and a second reception radio wave in which the second radio unit received a second transmission radio wave which includes a second signal transmitted by a second user terminal located in an area of a second cell formed by the second radio unit, perform removal processing to remove a component of the first transmission radio wave contained as an interference wave in the second reception radio wave, and
wherein the removal processing performing unit removes the component of the first transmission radio wave from the second reception radio wave by identifying the component of the first transmission radio wave contained as the interference wave in the second reception radio wave based on a phase derived from the first reception radio wave.
