METHOD FOR OPERATING IOT IN CELLULAR SYSTEM AND SYSTEM THEREFOR |
摘要 |
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 device performing the narrow IoT communication and the base station; transmitting system information including a two-bit mode indication field which indicates an operation mode for performing the narrow IoT communication, 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, included in the system information, wherein the operation modes include a standalone mode, a guard-band mode, an in-band mode in which the cellular system and the narrow band IoT communication use the same cell ID, and an in-band mode in which the cellular system and the narrow band IoT communication use different cell IDs. |
