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: Disclosed herein are a method and apparatus for transmitting/receiving an uplink signal. A user equipment transmits a first uplink channel within a first transmission time interval (TTI); transmits a second uplink channel within a second TTI; and transmits a first demodulation reference signal (DMRS) for the first uplink channel and a second DMRS for the second uplink channel on a same time symbol. The user equipment generates the first DMRS and the second DMRS based on a same TTI index.
