Electronic Device and Method for Adaptively Selecting Antenna

An electronic device comprising:

• wireless communication circuitry configured to support EN (Evolved-Universal Terrestrial Radio Access (E-UTRA)-New Radio (NR))-DC (dual connectivity);
• a first antenna configured for at least one first Long-term evolution (LTE) frequency band;
• a second antenna configured for at least one second LTE frequency band and at least one first new radio (NR) frequency band;
• a third antenna configured for at least one second NR frequency band;
• an NR transmission/reception antenna configured for the at least one first NR frequency band and the at least one second NR frequency band;
• and
• at least one processor, comprising processing circuitry, wherein the at least one processor, individually and/or collectively, is configured to control the wireless communication circuitry to:
• identify an anchor antenna of the first antenna and the second antenna, based on a frequency band of an LTE carrier of the EN-DC,
• identify a frequency band of an NR carrier of the EN-DC,
• identify an additional antenna for transmitting an NR carrier signal of the EN-DC of the second antenna and the third antenna, based on the anchor antenna and the frequency band of the NR carrier of the EN-DC, and
• provide the NR carrier signal of the EN-DC to the NR transmission/reception antenna and the additional antenna.
