Abstract: The present disclosure relates to a sensor network, Machine Type Communication (MTC), Machine-to-Machine (M2M) communication, and technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the above technologies, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Disclosed are an apparatus and method for generating distress signals in a mobile device. The apparatus comprises a coil antenna for NFC communication, a first communication circuit configured to perform the NFC communication using the coil antenna in a normal mode, a second communication circuit transmitting a distress signal having a rescue-dedicated frequency through the coil antenna in a distress mode, a switch connecting the coil antenna to the first communication circuit or the second communication circuit, and a processor determining the normal mode or the distress mode to control the switch.

Abstract: The present disclosure relates to a communication technique for combining a 5G communication system for supporting a higher data transmission rate than a 4G system with an IoT technology, and a system therefor. The present disclosure can be applied to 5G communication technology and IoT related technology-based intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, security and safety related services, etc.). A method in which a transmitter estimates a position in a communication system according to an embodiment of the present disclosure comprises the steps of: transmitting, to a receiver, a magnetic field signal generated from a single coil included in the transmitter; and receiving, from the receiver, position information estimated on the basis of a received signal strength of the magnetic field signal.
