Method and device for multi-subscriber identity module (SIM) wireless communication

A multi-subscriber identity module (SIM) wireless communication device comprising:

• a first SIM;
• a second SIM;
• a multi-SIM processor configured to receive a communication request by the second SIM while performing wireless communication based on the first SIM via a plurality of antennas, and to generate a first wireless communication signal based on the first SIM and a second wireless communication signal based on the second SIM when a number of antennas predicted for wireless communication based on the first SIM and the second SIM is greater than a number of available antennas;
• and
• a communication circuit configured to transmit the first wireless communication signal via a first antenna group comprising a portion of the plurality of antennas and to transmit the second wireless communication signal via a second antenna group, the second group being differentiated from the first antenna group.

A method of scheduling multi-subscriber identity module (SIM) wireless communication, the method comprising:

• receiving a communication request by a second SIM while communicating with a first SIM using a plurality of antennas;
• determining that a sum of a number of antennas for wireless communication based on the first SIM and a number of antennas for wireless communication based on the second SIM is greater than a number of available antennas;
• allocating a first antenna group comprising a portion of the plurality of antennas to a first wireless communication based on the first SIM in response to the determination;
• allocating a second antenna group to a second wireless communication based on the second SIM, the second antenna group being differentiated from the first antenna group;
• and
• scheduling wireless communication so that a frequency range in which the first wireless communication is performed overlaps a frequency range in which the second wireless communication is performed.
