Terminal method and device for switching antenna in real-time

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.
