A method of transmitting an uplink signal by a machine type communication, MTC, user equipment, UE, in a wireless communication system, the method comprising: transmitting (S1110) a first uplink signal through a first subband in a first subframe; retuning (S1115) a frequency of the MTC UE from the first subband to a second subband; and transmitting (S1120) a second uplink signal through the second subband in a second subframe, when the first subframe and the second subframe are consecutive: for the retuning of the frequency, the MTC UE does not transmit the first uplink signal or the second uplink signal in at least parts of last n symbols of the first subframe and first n symbols of the second subframe, wherein positions of the at least parts of the symbols, used for frequency re-tuning within a range of the last n symbols of the first subframe to the first n symbols of the second subframe, are determined according to a predetermined priority between the first uplink signal and the second uplink signal, wherein the at least parts of the symbols in which frequency retuning is performed are set to the first n symbols of the second subframe when the first uplink signal is a physical uplink control channel, PUCCH, and the second uplink signal is a physical uplink shared channel, PUSCH, and wherein the at least parts of the symbols in which frequency retuning is performed are set to the last n symbols of the first subframe when the first uplink signal is the PUSCH and the second uplink signal is the PUCCH. transmitting (S1110) a first uplink signal through a first subband in a first subframe; retuning (S1115) a frequency of the MTC UE from the first subband to a second subband; and transmitting (S1120) a second uplink signal through the second subband in a second subframe, when the first subframe and the second subframe are consecutive: for the retuning of the frequency, the MTC UE does not transmit the first uplink signal or the second uplink signal in at least parts of last n symbols of the first subframe and first n symbols of the second subframe, wherein positions of the at least parts of the symbols, used for frequency re-tuning within a range of the last n symbols of the first subframe to the first n symbols of the second subframe, are determined according to a predetermined priority between the first uplink signal and the second uplink signal, wherein the at least parts of the symbols in which frequency retuning is performed are set to the first n symbols of the second subframe when the first uplink signal is a physical uplink control channel, PUCCH, and the second uplink signal is a physical uplink shared channel, PUSCH, and wherein the at least parts of the symbols in which frequency retuning is performed are set to the last n symbols of the first subframe when the first uplink signal is the PUSCH and the second uplink signal is the PUCCH. for the retuning of the frequency, the MTC UE does not transmit the first uplink signal or the second uplink signal in at least parts of last n symbols of the first subframe and first n symbols of the second subframe, wherein positions of the at least parts of the symbols, used for frequency re-tuning within a range of the last n symbols of the first subframe to the first n symbols of the second subframe, are determined according to a predetermined priority between the first uplink signal and the second uplink signal, wherein the at least parts of the symbols in which frequency retuning is performed are set to the first n symbols of the second subframe when the first uplink signal is a physical uplink control channel, PUCCH, and the second uplink signal is a physical uplink shared channel, PUSCH, and wherein the at least parts of the symbols in which frequency retuning is performed are set to the last n symbols of the first subframe when the first uplink signal is the PUSCH and the second uplink signal is the PUCCH. <EOS>
