Abstract: A method for broadcasting system information to a machine-type-communication (MTC) terminal performing machine-type-communication, the method including: repeatedly transmitting, by a base station, a plurality of system-information blocks (SIBs) and content associated with each of the plurality of SIBs, using a contiguous physical allocation of six physical resource blocks (PRBs); accumulatively detecting, by the MTC terminal, the plurality of SIBs and the content associated with each of the plurality of SIBs; detecting, by the MTC terminal, a plurality of change flags, each of the plurality of change flags representing a change of the content associated with each of the plurality of SIBs; and until a change flag of the plurality of change flags represents a change of the content, reusing, by the MTC terminal, the content of the SIB associated with the change flag from among the content associated with each of the plurality of SIBs.
