The present disclosure may be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or connected car, health care, digital education, retail business, a security and safety-related service, etc.) on the basis of 5G communication technology and IoT-related technology. The present invention proposes a method and a device, of a terminal using a millimeter wave, for selecting an antenna in order to transmit/receive a signal in a next-generation communication system. According to the present invention, the terminal may select, on the basis of information acquired from a sensor, an antenna having no physical contact or positioned in a relatively high position. ## Claims ### Claim 1 A method of a terminal for selecting an antenna for transmitting and receiving a signal using a millimeter wave, the method comprising: acquiring state information of the terminal from a plurality of types of sensors; selecting at least one antenna from among a plurality of antennas included in the terminal, based on the state information; and performing signal transmission and reception by using the at least one antenna, wherein the plurality of types of sensors comprises a grip sensor and a 6-axis sensor, wherein selecting the at least one antenna includes: determining whether a grip sensor interrupt is being received, during a period of time that the terminal is receiving the grip sensor interrupt, acquiring grip sensor information from the grip sensor, and selecting an antenna for the signal transmission and reception to select preferentially an antenna that physical contact is not occurred, based on the grip sensor information, and during the period of time that the terminal is free from receiving the grip sensor interrupt, acquiring 6-axis sensor information from the 6-axis sensor, and selecting an antenna for the signal transmission and reception, based on the 6-axis sensor information, and wherein the 6-axis sensor information indicates which antenna is positioned relatively above. ### Claim 2 (depends on 1) The method of claim 1, wherein, when the at least one antenna includes two or more antennas, the two or more antennas are disposed at different positions of the terminal. ### Claim 3 (depends on 1) The method of claim 1, wherein the state information of the terminal includes at least one of movement state information or usage state information of the terminal. ### Claim 4 (depends on 1) The method of claim 1, wherein the state information of the terminal includes at least one of information indicating whether a physical contact of the at least one antenna is occurred, information indicating a relative position of the at least one antenna, or movement status information of the terminal. ### Claim 5 (depends on 1) The method of claim 1, wherein selecting the at least one antenna is performed to select an antenna with a strong possibility of having a good channel state. ### Claim 6 (depends on 1) The method of claim 1, wherein selecting the antenna for the signal transmission and reception, based on the grip sensor information, is performed based on predefined relationship information that correlates the grip sensor information to first and second states of the antenna. ### Claim 7 A terminal for selecting an antenna for transmitting and receiving a signal using a millimeter wave, the terminal comprising: a radio frequency (RF) unit including a plurality of antennas; a plurality of types of sensors; and a controller connected to the RF unit and the plurality of types of sensors configured to: control acquiring state information of the terminal from the plurality of types of sensors, select at least one antenna from among the plurality of antennas, based on the state information, and perform signal transmission and reception by using the at least one antenna, wherein the plurality of types of sensors comprises a grip sensor and a 6-axis sensor, wherein the controller is further configured to: determine whether a grip sensor interrupt is being received, during a period of time that the terminal is receiving the grip sensor interrupt, acquire grip sensor information from the grip sensor, and select an antenna for the signal transmission and reception to preferentially select an antenna having no physical contact, based on the grip sensor information, and during the period of time that the terminal is free from receiving the grip sensor interrupt, acquire 6-axis sensor information from the 6-axis sensor and select an antenna for the signal transmission and reception, based on the 6-axis sensor information, and wherein the 6-axis sensor information indicates which antenna is positioned relatively above. ### Claim 8 (depends on 7) The terminal of claim 7, wherein, when the at least one antenna includes two or more antennas, the two or more antennas are disposed at different positions of the terminal. ### Claim 9 (depends on 7) The terminal of claim 7, wherein the state information of the terminal includes at least one of movement state information or usage state information of the terminal. ### Claim 10 (depends on 7) The terminal of claim 7, wherein the state information of the terminal includes at least one of information indicating whether a physical contact of the at least one antenna is occurred, information indicating a relative position of the at least one antenna, or movement status information of the terminal. ### Claim 11 (depends on 7) The terminal of claim 7, wherein the controller further controls selecting an antenna with a strong possibility of having a good channel state.
