Classification: CPC H | IPC H

Claim 12:
13. A drone reporting channel state information (CSI) for beamforming based on an antenna array in a wireless communication system, comprising:
a transceiver configured to transmit/receive RF signals;
a memory; and
a processor connected to the transceiver and the memory,
wherein the processor is configured:
to receive a channel state information reference signal (CSI-RS);
to generate channel state information using the CSI-RS and a codebook generated in advance; and
to report the channel state information,
wherein the channel state information includes information related to a codevector determined in the codebook,
the antenna array has a three-dimensional shape having omnidirectional symmetry,
the codebook is generated based on a position of the drone having the center of the three-dimensional shape as an origin, and
the position of the drone is represented based on a polar coordinate system.
