deactivating at least one second antenna, among the plurality of antennas, based on the plurality of states associated with the plurality of antennas,
wherein the plurality of states are based on a relative position associated with each antenna of the plurality of antennas arranged in the terminal, and
wherein the at least one first antenna is activated if the at least one first antenna is positioned upward of the terminal.
2. The method of claim 1 , wherein the plurality of states associated with the plurality of antennas are determined based on at least one of a signal transmitted or received through at least one antenna, among the plurality of antennas, that is currently activated and sensor data generated by at least one sensor arranged in the terminal.
3. The method of claim 1 , wherein the at least one second antenna is deactivated if a position where the at least one second antenna is installed is blocked by another object.
4. The method of claim 1 , wherein the at least one first antenna is activated if the at least one first antenna is positioned higher than another at least one antenna among the plurality of antennas.
5. The method of claim 1 , wherein the at least one first antenna is activated if the at least one first antenna is positioned over an image displayed on the terminal.
6. The method of claim 1 , wherein the at least one first antenna is activated if the at least one first antenna is positioned in a reception direction of a signal from a base station.
7. The method of claim 1 , wherein the at least one first antenna is activated based on at least one of a best beam, a result of estimating an angle of arrival (AOA), an angle of the best beam, or strength of a received signal.
8. The method of claim 1 ,
wherein the detecting of the plurality of states associated with the plurality of antennas further includes determining a reception direction of a signal at a default antenna, among the plurality of antennas, that is activated if the terminal is turned on, and
wherein the at least one first antenna includes an antenna corresponding to the reception direction of the signal at the default antenna.
9. The method of claim 8 , wherein the default antenna is arranged at a center of a front side or a rear side of the terminal.
10. The method of claim 1 ,
wherein activation of the at least one first antenna and deactivation of the at least one second antenna are allowed during a non-data period, and
wherein the non-data period includes a period in which at least one of a signal for synchronization or synchronization tracking, a signal for beam measurement or tracking, a signal used for automatic gain control (AGC), or a signal used for beam changing is received.
11. A terminal in a wireless communication system, the terminal comprising:
a plurality of antennas;
a transceiver coupled to the plurality of antennas; and
at least one processor coupled to the transceiver,
wherein the at least one processor is configured to:
detect a plurality of states associated with the plurality of antennas,
activate at least one first antenna, among the plurality of antennas, based on the plurality of states associated with the plurality of antennas, and
deactivate at least one second antenna, among the plurality of antennas, based on the plurality of states associated with the plurality of antennas,
wherein the plurality of states are based on a relative position associated with each antenna of the plurality of antennas arranged in the terminal, and
wherein the at least one first antenna is activated if the at least one first antenna is positioned upward of the terminal.
12. The terminal of claim 11 , wherein the plurality of states associated with the plurality of antennas are determined based on at least one of a signal transmitted or received through currently activated at least one antenna or sensor data generated by at least one sensor arranged in the terminal.
13. The terminal of claim 11 , wherein the at least one second antenna is deactivated if a position where the at least one second antenna is installed is blocked by another object.
14. The terminal of claim 11 , wherein the at least one first antenna is activated if the at least one first antenna is positioned higher than another at least one antenna, among the plurality of antennas.
15. The terminal of claim 11 , wherein the at least one first antenna is activated if the at least one first antenna is positioned over an image displayed on the terminal.
16. The terminal of claim 11 , wherein the at least one first antenna is activated if the at least one first antenna is positioned in a reception direction of a signal from a base station.
17. The terminal of claim 11 , wherein the at least one first antenna is activated based on at least one of a best beam, a result of estimating an angle of arrival (AOA), an angle of the best beam, or strength of a received signal.
18. The terminal of claim 11 ,
wherein the at least one processor is further configured to determine a reception direction of a signal at a default antenna, among the plurality of antennas, that is activated if the terminal is turned on, and
wherein the at least one first antenna includes an antenna corresponding to the reception direction of the signal at the default antenna.
19. The terminal of claim 18 , wherein the default antenna is arranged at a center of a front side or a rear side of the terminal.
