A communication device mounted on a vehicle and an operation method of the communication device are provided. The communication device performs a connection with a communication terminal included in a vehicle stopped or driving in a vicinity of the vehicle via device-to-device communication, provide subscriber identity module (SIM) information to the connected communication terminal, request execution of a communication relay function from the communication terminal, and in response to a communication relay function acceptance signal being received from the communication terminal, transmit and receive data to and from the base station by using the communication terminal as a communication relay.

Communication device mounted on vehicle and operation method therefor

A method of establishing a communication link is provided. The method includes monitoring a heading direction of a vehicle, in case that the heading direction of the vehicle is changed by at least as much as a preset angle, determining a search order between a plurality of antenna modules in consideration of the changed heading direction of the vehicle and mounting positions of the plurality of antenna modules mounted on the vehicle, evaluating the plurality of antenna modules according to the search order, and communicating with a base station via a new antenna module selected based on a result of the evaluating, rather than via an old antenna module used for communication with the base station.

Communication control device, and method for establishing communication link by using same

Provided are an electronic device mounted on a battery powered electric vehicle and an operation method thereof. The electronic device may calculate estimated battery consumption for the vehicle to be driven to a destination, identify a current remaining capacity of the battery, and determine, based at least in part on the identified remaining capacity of the battery and the estimated battery consumption, whether to switch from a first communication mode (e.g., a fifth generation (5G) millimeter wave (mmWave)) in current use, to a second communication mode that consumes battery power at a different rate.

Electronic device mounted on vehicle and operation method thereof

An electronic device according to a disclosed embodiment includes a first antenna, a second antenna, a first communication circuit configured to communicate in a first frequency band with the first antenna at a first data rate, a second communication circuit configured to communicate in a second frequency band with the second antenna at a second data rate, a first coupler electrically connected between the first antenna and the first communication circuit, and at least one communication circuit configured to control to identify, during at least part of a period of simultaneously transmitting a first transmit signal with the first antenna and a second transmit signal with the second antenna, an amplitude of a first receive signal including at least part of the second transmit signal detected by the first coupler, disable an operation of attenuating the at least part of the second transmit signal included in the first receive signal based on the amplitude of the first receive signal falling in a first designated range, and enable the operation of attenuating the at least part of the second transmit signal included in the first receive signal based on the amplitude of the first receive signal falling in a second designated range.

Electronic device for attenuating at least part of signal received by antenna and method for controlling communication signal

Provided are an electronic device for determining failure of a signal path and a component, and a method for operating the electronic device according to various embodiments. The electronic device comprises: at least one connection part for connection to an external device; a first signal path including an amplifier for amplifying a signal transmitted to the outside of the electronic device; a second signal path for obtaining another signal from the outside of the electronic device; an antenna port electrically connected to the first signal path and the second signal path through a filter circuit; and a communication module, wherein the communication module may be configured to transmit a transmission signal through the first signal path to the antenna port, obtain at least a part of the transmission signal through the second signal path, and determine whether the electronic device is defective on the basis of the transmission signal and information associated with at least a part of the transmission signal. Various other embodiments are possible.
