1. A method for receiving system information, the method performed by a machine type communication (MTC) device and comprising:
- repeatedly receiving, by the MTC device from a base station, control information through physical downlink control channels (PDCCHs) on several subframes;
decoding the control information which includes scheduling information regarding a plurality of first type system information blocks (SIBs) for the MTC device;
determining multiple successive subframes which receive the plurality of first type SIBs through physical downlink shared channels (PDSCHs) based on the control information;
receiving, by the MTC device from the base station, the plurality of first type SIBs for the MTC device on the multiple successive subframes through the PDSCHs based on the scheduling information; and
decoding the plurality of first type SIBs for the MTC device on the multiple successive subframes,wherein a subframe for receiving the plurality of first type SIBs for the MTC device is started after a plurality of gap subframes from a last subframe on which the control information is repeatedly received.

Abstract
According to one disclosure of the present specification, when a machine type communication (MTC) device is located in a coverage-expanded area of a base station, the MTC device repeatedly receives system information (for example, system information blocks (SIBs) of a first type) on several subframes and then combines and decodes the received SIBs, thereby improving a decoding success rate.

9. A machine type communication (MTC) device, comprising:
-
a transceiver configured to; repeatedly receive, from a base station, scheduling information regarding a plurality of first type system information blocks (SIBs) for the MTC device through physical downlink control channels (PDCCHs) on several subframes, and receive, from the base station, the plurality of first type SIBs for the MTC device on multiple successive subframes through physical downlink shared channels (PDSCHs) based on the scheduling information; and a processor configured to; decode the scheduling information, determine the multiple successive subframes which receive the plurality of first type SIBs for the MTC device based on the decoded scheduling information, and decode the plurality of first type SIBs for the MTC device on the multiple successive subframes, wherein a subframe for receiving the plurality of first type SIBs for the MTC device is started after a plurality of gap subframes from a last subframe on which the control information is repeatedly received. - View Dependent Claims (10, 11, 12, 13, 14, 15)
