The present disclosure provides a method for a multi-subscriber identity module (SIM) wireless communication. The method includes receiving a communication request, performing a first wireless communication, and performing a second wireless communication. Receiving a communication request by a second SIM while in wireless communication is based on a first SIM is performed via a plurality of antennas. Performing a first wireless communication is based on the first SIM communicating via a first antenna group that is a portion of the plurality of antennas, in response to a number of antennas used for wireless communication based on the first SIM and the second SIM that is greater than a number of available antennas of a terminal. Performing a second wireless communication is based on the second SIM via a second antenna group while the first wireless communication is performed and the second group is different from the first antenna group.

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

A method of operating a wireless communication apparatus is described. The method includes receiving, a repeated physical downlink control channel (PDCCH) from a base station, performing blind decoding on a plurality of candidate PDCCHs, performing a cyclic redundancy check (CRC), comparing the at least two pieces of control information with each other, and determining whether to terminate the blind decoding based on the comparison.

Wireless communication apparatus and operation method thereof

A device is provided. The device includes a housing forming at least one portion of a surface of the device, wherein the at least one portion of the surface includes first and second surfaces facing opposite to each other; a display at least partially housed in the housing and including a display area visible via at least one portion of the first surface; a substantially circular radiating element at least partially forming the first surface; a ground element between the first and second surfaces; a conductive element below the ground element; wireless communication circuitry electrically connected with the radiating element and establishing communication with an external electronic device; and a processor electrically connecting the conductive element with the ground element if a radiation characteristic relative to the radiating element satisfies a condition; and disconnecting the conductive element with the ground element if the radiation characteristic does not satisfy the condition.

Electronic device including antenna device

A portable electronic device cover, according to the present invention, comprises a conductive plate which is spaced at a predetermined distance from an antenna mounted in a portable electronic device and is arranged at a position overlapped with at least a part of the antenna when the portable electronic device is mounted in the portable electronic device cover.

Portable electronic device cover

An electronic device and a method of operating an electronic device are provided. The electronic device includes a housing including a first face and a second face that faces in a direction opposite to the first face; a display exposed through the first face of the housing; a ground member disposed between the first face and the second face; an antenna radiator at least partially disposed within the housing and/or on a portion of the housing; a communication circuit electrically connected to the antenna radiator; a conductive member disposed within the housing or forming a portion of the second face of the housing; and a control circuit electrically connected to the ground member and the conductive member, wherein the control circuit is configured to selectively connect the conductive member to the ground member if the antenna radiator and the communication circuit are electrically connected to each other.
