Abstract: The present disclosure provides a method for a machine type communication (MTC) device to receive a hybrid automatic repeat request (HARQ) acknowledgement (ACK)/non-acknowledgement (NACK) signal. The method can include the steps of: the MTC device transmitting a physical uplink control channel (PUCCH) including uplink data; the MTC device determining a radio network temporary identifier (RNTI) for itself from among a plurality of new RNTIs; monitoring the reception of a downlink control channel in a search space; and receiving a HARQ ACK/NACK signal for the transmission of the uplink data by decoding a downlink control channel scrambled with the determined RNTI.

Abstract: One disclosure of the present invention provides a discovery signal receiving method. The method may comprise the steps of: identifying, through a physical control format indicator channel (PCFICH) received from a small-scale cell over a first orthogonal frequency division multiplexing (OFDM) symbol of a downlink sub-frame, the position of an OFDM symbol over which a downlink control channel is received; and determining a resource region on which a discovery signal is received from the small-scale cell. In the determining step, it can be assumed that the resource region on which the discovery signal is received does not overlap a resource region on the OFDM symbol over which the downlink control channel is received.

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 is provided for performing discovery signal measurements. A user equipment (UE) receives measurement configuration information including a sub-frame offset. The sub-frame offset indicates an offset between a secondary synchronization signal (SSS) and a channel-state information reference signal (CSI-RS) in a discovery signal. The sub-frame offset has a maximum value of four (4). The UE determines a sub-frame for the SSS in the discovery signal, and determines a sub-frame for the CSI-RS based on the sub-frame offset and the sub-frame for the SSS in the discovery signal. The UE performs a measurement on the discovery signal based on the CSI-RS.
