There are provided an encoding method and an encoder performing an encoding by an operation of generating a first output message by encoding an input message based on a first block code, an operation of generating a second output message by encoding some of the input message based on a second block code, and an operation of concatenating the first output message and the second output message.

Method and apparatus for performing encoding using block code having input/output of variable length

A method of performing a downlink machine type communication from a base station to a MTC (machine type communication) terminal includes, at the base station, transmitting at least one of a system information&#x2014;the system information excluding a Master Information Block (MIB)&#x2014;, a control information and data to the MTC terminal using a system bandwidth having a predetermined size. The base station performs frequency hopping using a frequency hopping pattern in a unit of narrow band on the at least one of the system information&#x2014;the system information excluding a Master Information Block (MIB)&#x2014;, the control information and the data to transmit to the MTC terminal, and the narrow band is less than the system bandwidth.

Method for performing machine type communication for the purpose of coverage improvement, apparatuses and systems for performing the same

Provided are a method, an Internet of Things (IoT) device, and a base station apparatus for subscriber authentication without using a SIM card or a USIM card in a IoT/IosT service based on a 3GPP mobile communication system. The method of authenticating a subscriber of an Internet of Things (IoT) device based on mobile communication includes authenticating the subscriber using a measurement value which becomes a unique characteristic of the IoT device, in which the authenticating of the subscriber is performed using a measurement value which becomes a unique characteristic of the IoT device without using a SIM (subscriber identity module) card or a USIM (universal subscriber identity module) card.
