Abstract: A method for transmitting data by a transmission node in a wireless communication system is provided. The method includes transmitting, to a base station, a channel information request, transmitting, to the base station, a data packet based on a first channel information value received in response to the transmitted channel information request, and awaiting reception of a response packet indicating reception of the data packet from the base station, if the reception of the response packet fails during a predetermined time interval, detecting an energy level of a signal received in the predetermined time interval, and reconfiguring one of a transmitting method for the response packet and a transmitting method for a next data packet based on the detected energy level.

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. Embodiments of the present invention provide a device and a method for estimating a position between wireless apparatuses using a signal transmitted and received between wireless apparatuses in a wireless communication system. A device of a first wireless apparatus for estimating a position comprises: a transceiver for transmitting and receiving a signal to and from a second wireless apparatus; and a position estimator for estimating a position of the second wireless apparatus using a signal transmitted and received through the transceiver. The position estimator comprises a range estimator for estimating the distance between the first wireless apparatus and the second wireless apparatus on the basis of a first time difference from a time point at which a request range packet is transmitted to the second wireless apparatus to a time point at which the reception of a response range packet transmitted from the second wireless apparatus is sensed and a second time difference from a time point at which the reception of the required range packet is sensed by the second wireless apparatus to a time point at which the response range packet is transmitted.

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. An apparatus and method for measuring a distance between wireless devices using a first signal transmitted/received between the wireless devices in a wireless communication system are provided. The method includes: receiving the first signal for distance measurement transmitted from a first of the wireless devices; receiving a signal reflected by a reflector after being transmitted from the first of the wireless devices; and based on the received first signal and the received reflected signal, estimating a distance between the second of the wireless devices and the reflector.

Abstract: A method and apparatus for reducing power consumption in a mobile device of a wireless communication system when discovering a central node is provided. The method for operating of a terminal for discovering at least one central node in a wireless communication system includes: generating a probe request signal and transmitting the probe request signal to at least one central node; after transmitting the probe request signal, switching from a normal mode to a low power mode and driving the terminal in the low power mode; in response to a mode switch instruction signal being received from the central node, switching the terminal from the low power mode to the normal mode; and receiving a probe response signal to the probe request signal from the central node in the normal mode.
