Abstract: A method for performing uplink transmission by a Machine Type Communication (MTC) User Equipment (UE) in a wireless access system supporting an MTC is discussed. The method performed by the MTC UE includes repeatedly transmitting a Physical Uplink Control Channel (PUCCH) N1 times during N1 subframes, where N1 is an integer larger than 1, and repeatedly transmitting 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 MTC UE transmits only the at least one of the N1 PUCCHs at the at least one overlapped subframe.

Abstract: A method and a device for performing a random access in a wireless communication system are provided. Specifically, a wireless resource for transmitting a first random access request is selected, and the first random access request is transmitted through the wireless resource. The first random access request includes a transmission period of the first random access request, the frequency of retransmission, and an allowable error of the transmission period. Uplink resource allocation information is received in response to the first random access request. The uplink resource allocation information includes information on an indicator bit and a wireless resource shift. When the indicator bit is a preset value, a second random access request is transmitted through a wireless resource shifted from the wireless resource.
