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: Provided are a method for transmitting and receiving signals in a wireless communication system including machine type communication (MTC), and a base station and a terminal therefor. The method for transmitting and receiving signals comprises the steps of: receiving repeatedly reference signals from a plurality of resource units; determining whether to perform bundling for the reference signals transmitted from at least one resource unit among the plurality of resource units; and, when it has been decided to perform bundling, estimating a channel by assuming the same precoding for the reference signals transmitted from the at least one resource unit. Whether to perform bundling is determined on the basis of the number of repetition of the reference signals and/or the number of antenna ports.

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.
