Method and apparatus for signal transmission using narrow band in wirelss cellular communication system

The present disclosure relates to 5G communication system to support higher data rates than the 4G system after the communication technique and system that fuses with the IoT technology. This disclosure is for the intelligent services (e.g., based on the 5G technologies and IoT related technologies, smart home, smart buildings, smart city, smart card, or, connected cars, health care, digital educational, retail, security and safety services, ) it can be applied to. The invention relates to a method and apparatus for operating a, in particular down-link and up-link signal sent from the system supporting the IoT terminal for transmitting and receiving by using only one subcarrier as for the wireless communication system. Specifically, the allocation of resources for IoT terminal, from the resource by the base station that supports the terminal and the IoT IoT terminal provides a method for transmitting and receiving signals in a particular sub-carrier.
