The method comprises the steps of: receiving information about SPS transmission periods; confirming information about the number of SPS repetitions; and receiving SPS data, which is newly and repeatedly transmitted in every SPS transmission period, on the basis of the SPS transmission periods and the number of the SPS repetitions, wherein, if the SPS transmission periods are greater than the number of the SPS repetitions, a frequency band in which the SPS data is received is maintained to be the same in every SPS transmission period and, if the SPS transmission periods are smaller than the number of the SPS repetitions, the frequency band in which the SPS data is received is switched in every SPS transmission period. ## Claims ### Claim 1 A method for receiving data by a user equipment in a wireless communication system, the method comprising: receiving information about a semi-persistent scheduling (SPS) transmission period; checking information about the number of SPS repetitions; and receiving new SPS data repeatedly transmitted in every SPS transmission period based on the SPS transmission period and the number of SPS repetitions, wherein, when the SPS transmission period is longer than the number of SPS repetitions, a frequency band in which the SPS data is received is maintained to be the same in every SPS transmission period, and wherein, when the SPS transmission period is shorter than the number of SPS repetitions, the frequency band in which the SPS data is received is switched in every SPS transmission period. ### Claim 2 (depends on 1) The method according to claim 1, wherein, when the SPS transmission period is shorter than the number of SPS repetitions, previous SPS data and current SPS data are simultaneously received in different frequency bands at a time when each SPS transmission period starts. ### Claim 3 (depends on 1) The method according to claim 1, wherein, when the SPS transmission period is shorter than the number of SPS repetitions, a hybrid ARQ (HARQ) process ID for the SPS data is determined based on the frequency band in which the SPS data is received. ### Claim 4 (depends on 1) The method according to claim 1, wherein the information about the SPS transmission period is received through radio resource control (RRC) signaling, and the information about the number of SPS repetitions is received on a physical downlink control channel (PDCCH) indicating SPS activation. ### Claim 5 (depends on 1) The method according to claim 1, wherein the SPS data comprises machine-type communication (MTC) data and a maximum size of each of the frequency bands is 6 physical resource blocks (PRBs). ### Claim 6 (depends on 5) The method according to claim 5, further comprising: receiving information indicating an SPS transmission band, wherein, when the SPS transmission band is wider than 6 PRBs, the SPS transmission band is limited to a multiple of 6 PRBs, and the SPS data is repeatedly received on the 6 PRBs [the SPS transmission band/6 PRBs] times. ### Claim 7 A user equipment (UE) used in a wireless communication system, the user equipment comprising: a radio frequency (RF) unit; and a processor configured to control the RF unit, wherein the processor is configured to: receive information about a semi-persistent scheduling (SPS) transmission period; check information about the number of SPS repetitions;
