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 and apparatus for allocating resources for a machine type communication user equipment (MTC UE) in a wireless communication system is provided. A base station indicates a transport block size (TBS) directly, adapts a code rate according to repetition numbers across multiple subframes in a MTC physical downlink shared channel (M-PDSCH) for the MTC UE, and allocates resources for the M-PDSCH by using the indicated transport block size and the adapted code rate. The TBS may be determined based on a modulation and coding scheme (MCS) only.

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.

Abstract: The present invention relates to a wireless access system that supports unlicensed bands, and relates to a method for reporting channel state information when a partial subframe (pSF) is formed. A method for user equipment (UE) reporting channel state information (CSI) in a wireless access system that supports unlicensed bands according to an embodiment of the present invention may comprise the steps of: receiving a downlink burst configured to an unlicensed band cell (U cell) supporting unlicensed bands as far as a certain subframe; measuring CSI with respect to the downlink burst; and reporting the measured CSI to a base station. In this regard, if a pSF is included in the downlink burst, the UE does not consider the pSF to be a valid downlink subframe for CSI measurement, and the pSF may be formed to have a smaller size than a general subframe.

Abstract: The disclosure of the present specification provides a method for receiving a downlink control channel in a machine type communication (MTC) device configured to operate in only a partial band of the system band of a cell. The method may comprise the steps of: considering the number of physical resource block (PRB) pairs, to which a downlink control channel can be mapped, to be one of 2, 4, and 8; when the considered number of PRB pairs is greater than the number of PRB pairs to which the downlink control channel is actually mapped, determining that the downlink control channel is not included in PRB pairs except the number of PRB pairs to which the downlink control channel is actually mapped; and receiving the downlink control channel in only as many PRB pairs as the number of PRB pairs to which the downlink control channel is actually mapped, on the basis of the determination.

Abstract: A disclosure of the present specification provides a method for transmitting an uplink channel and a demodulation reference signal (DMRS) by a machine type communication (MTC) device. The method may comprise the steps of: determining a frequency resource area for transmitting an uplink channel so as to have a size equal to or smaller than the size of a physical resource block (PRB) including 12 subcarriers; generating a DMRS sequence for some sub-carriers among the 12 subcarriers when the frequency resource area for transmitting the uplink channel is determined to have a size smaller than the size of the PRB including the 12 subcarriers; and transmitting the uplink channel and the DMRS on the some subcarriers in the PRB.
