Abstract
The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate beyond a 4G communication system such as LTE. The present disclosure provides a method for supporting a device performing narrow band Internet of things (IoT) communication by a base station in a cellular system, the method comprising the operations of: transmitting a synchronization sequence for synchronization between the base station and the device performing the narrow IoT communication; transmitting system information including a two-bit mode indication field which indicates an operation mode for performing the narrow IoT communication, the operation corresponding to one of a plurality of operation modes; and transmitting a control channel and a data channel on the basis of parameters for the narrow band IoT communication, the parameter being included in the system information, wherein the operation modes include at least one of a standalone mode, a guard-band mode, an in-band mode in which the cellular system and the narrow band IoT communication use a common cell ID, or an in-band mode in which the cellular system and the narrow band IoT communication use diff…
