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 different cell IDs.

Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate than a 4G communication system such as LTE. A method for performing, by a terminal, random access in a wireless communication system, according to an embodiment of the present disclosure, comprises the steps of: receiving, from a base station, system information including configuration information of resources allocated for random access allocated on the basis of at least one of a user group and a coverage class; identifying, from the configuration information, configuration information of resources for random access, corresponding to the user group in which the terminal is included, or the coverage class of the terminal; and transmitting a random access request to the base station using resources corresponding to the identified configuration information of the resources for random access.
