Abstract: An electronic device and an operation method thereof are disclosed. The disclosed electronic device may include: a processor, a memory configured to store at least one instruction executable by the processor, and a communicator, wherein the communicator may include a first antenna, a second antenna, a first filter configured to allow a radio frequency (RF) signal in a first frequency band to pass therethrough, and a second filter configured to allow an RF signal in a second frequency band to pass therethrough, and the processor is configured, in response to the at least one instruction being executed by the processor, to: connect to an access point using one of the first frequency band, the second frequency band, and a third frequency band, and control a connection between the first antenna and the first filter and a connection between the second antenna and the second filter based on a communication channel between the electronic device and the access point and a communication channel of a peer-to-peer (P2P) connection, in response to performing the P2P connection with a peripheral device.

Abstract: An electronic device includes a first processor, a second processor; and a communication interface. The second processor transmits, via a hardware wire, state information indicating a state of the first processor to the communication interface; and based on the first processor entering a suspend mode from a normal mode, change the state information from a first value to a second value, and the communication interface, based on the state information being changed, disconnects the first processor from the communication interface by turning off power of an universal serial bus (USB) interface. Moreover, the second processor, based on the first processor entering the normal mode from the suspend mode, changes the state information from the second value to the first value, and the communication interface, based on the state information being changed, connects the first processor to the communication interface by turning on the power of the USB interface.
