Abstract: The present specification provides a reception method of a machine type communication (MTC) device. The reception method can comprise the steps of: receiving a control channel through the entire system bandwidth on first and second orthogonal frequency division multiplexing (OFDM) symbols of a subframe; and determining whether to receive a data channel only in a reduced bandwidth compared with the system bandwidth from the third symbol of the subframe. At this point, when the control channel does not continue up until a third symbol of the subframe, the data channel can be received in a reduced bandwidth compared with the system bandwidth from the third symbol of the subframe.

Abstract: A method and apparatus for receiving a downlink message in a wireless communication system is provided. A user equipment (UE) receives scheduling information for a downlink message via a dedicated common search space (D-CSS) in a first narrowband from a network, and receives the downlink message in the second narrowband from the network. The D-CSS may schedule resources for random access response (RAR)/Msg4 and initial configuration of UE-specific configurations before UE-specific narrowband (NB) is configured. CSS in UE-specific NB may schedule resources for RAR/Msg4/paging and reconfiguration of UE-specific configurations after UE-specific NB is configured.

Abstract: A method is provided for performing a random access procedure by a user equipment (UE) in a wireless communication system supporting coverage enhancement. The UE repeatedly transmits a physical random access channel (PRACH) signal, determines a random access radio network temporary identifier (RA-RNTI) corresponding to the PRACH signal using system frame number (SFN) information, wherein time index information and frequency index information are not used for determining the RA-RNTI, and monitors downlink control information masked by the determined RA-RNTI. The time index information indicates a subframe starting the repeated transmission of the PRACH signal, the frequency index information indicates a frequency index of the PRACH signal transmitted in the starting subframe, and the SFN information indicates a radio frame starting the repeated transmission of the PRACH signal.
