Methods and apparatuses for transmitting uplink in wireless access system supporting machine-type communication

A method for receiving uplink transmission from a Machine Type Communication (MTC) User Equipment (UE) in a wireless access system supporting an MTC, the method performed by an evolved Node B (eNB) and comprising:

• repeatedly receiving a Physical Uplink Control Channel (PUCCH) N1 times during N1 subframes, where N1 is an integer larger than 1;
• and
• repeatedly receiving a Physical Uplink Shared Channel (PUSCH) from the MTC UE N2 times during N2 subframes, where N2 is an integer larger than 1,
• wherein if at least one of the N2 subframes is overlapped with at least one of the N1 subframes, the at least one of the N1 PUCCH only is received at the at least one overlapped subframe.

An apparatus supporting a Machine Type Communication (MTC) for performing uplink transmission in a wireless access system, the apparatus comprising:

• a receiver;
• a transmitter;
• and
• a processor supporting the uplink transmission,
• wherein the processor is configured to:
• repeatedly transmit, by controlling the transmitter, a Physical Uplink Control Channel (PUCCH) N1 times during N1 subframes, where N1 is an integer larger than 1;
• and
• repeatedly transmit, by controlling the transmitter, a Physical Uplink Shared Channel (PUSCH) N2 times during N2 subframes, where N2 is an integer larger than 1,
• wherein if at least one of the N2 subframes is overlapped with at least one of the N1 subframes, the processor is configured to transmit only the at least one of the N1 PUCCHs at the at least one overlapped subframe.
