Specifically, the terminal receives a first physical downlink control channel (PDCCH) including first downlink control information (DCI) from a base station and receives a first PDSCH on the basis of the first DCI. Here, the first PDSCH may include indication information indicating whether a multi transport block is scheduled. The terminal receives a plurality of PDSCHs from the base station, wherein at least one PDSCH of the plurality of PDSCHs may be received without receiving a separate DCI according to the indication information. ## Claims ### Claim at position 1 1-16. (canceled) ### Claim 17 A method for receiving, by a user equipment (UE), multiple transport blocks in a wireless communication system supporting a narrow band-Internet of things (NB-IoT), the method comprising: receiving, from a base station, configuration information transmitted via a single cell-multicast control channel (SC-MCCH); receiving, from the base station, Downlink Control Information (DCI); and receiving multiple transport blocks based on the DCI, wherein the configuration information includes a configuration of each single cell-traffic channel (SC-MTCH) related to scheduling of the multiple transport blocks. ### Claim 18 (depends on 17) The method of claim 17, wherein the DCI includes information for a number of the multiple transport blocks. ### Claim 19 (depends on 18) The method of claim 18, wherein a cyclic redundancy check (CRC) of the DCI is scrambled with group-radio network temporary identifier (G-RNTI). ### Claim 20 (depends on 18) The method of claim 18, wherein a number of transport blocks scheduled for the SC-MTCH is indicated based on the information for the number of the multiple transport blocks. ### Claim 21 (depends on 18) The method of claim 18, wherein the maximum number of the multiple transport blocks is pre-defined. ### Claim 22 (depends on 17) The method of claim 17, wherein the multiple transport blocks are received via narrow band physical shared channel (NPDSCH). ### Claim 23 (depends on 17) The method of claim 17, wherein the configuration information further includes information indicating a scheduling gap between transport blocks. ### Claim 24 (depends on 23) The method of claim 23, wherein a scheduling gap between two consecutively transmitted transport blocks among the multiple transport blocks is configured based on the information indicating the scheduling gap. ### Claim 25 (depends on 24) The method of claim 24, wherein a number of subframes between a first transport block and a second transport block is indicated as a scheduling gap based on the information indicating the scheduling gap. ### Claim 26 (depends on 25) The method of claim 25, wherein the scheduling gap is a duration from a last subframe at which a NPDSCH including the first transport block is transmitted to a first subframe at which a transmission of a NPDSCH including the second transport block starts. ### Claim 27 (depends on 17) The method of claim 17, wherein the configuration information is related to single cell-point to multipoint (SC-PTM). ### Claim 28 A user equipment (UE) receiving multiple transport blocks in a wireless communication system supporting a narrow band-Internet of things (NB-IoT), the UE comprising: a transceiver for transmitting and receiving a radio signal; and a processor functionally connected to the transceiver, wherein the processor is configured to: receive, from a base station, configuration information transmitted via a single cell-multicast control channel (SC-MCCH), receive, from the base station, Downlink Control Information (DCI), and receive multiple transport blocks based on the DCI, and wherein the configuration information includes a configuration of each single cell-traffic channel (SC-MTCH) related to scheduling of the multiple transport blocks. ### Claim 29 (depends on 28) The UE of claim 28, wherein the DCI includes information for a number of the multiple transport blocks. ### Claim 30 (depends on 29) The UE of claim 29, wherein a cyclic redundancy check (CRC) of the DCI is scrambled with group-radio network temporary identifier (G-RNTI). ### Claim 31 (depends on 28) The UE of claim 28, wherein the configuration information further includes information indicating a scheduling gap between transport blocks. ### Claim 32 A method transmitting, by a base station, multiple transport blocks in a wireless communication system supporting a narrow band-Internet of things (NB-IoT), the method comprising: transmitting, to a user equipment (UE), configuration information transmitted via a single cell-multicast control channel (SC-MCCH); transmitting, to the UE, Downlink Control Information (DCI); and transmitting multiple transport blocks based on the DCI to the UE, wherein the configuration information includes a configuration of each single cell-traffic channel (SC-MTCH) related to scheduling of the multiple transport blocks. ### Claim 33 (depends on 32) The method of claim 32, wherein the DCI includes information for a number of the multiple transport blocks. ### Claim 34 (depends on 33) The method of claim 33, wherein a cyclic redundancy check (CRC) of the DCI is scrambled with group-radio network temporary identifier (G-RNTI). ### Claim 35 (depends on 32) The method of claim 32, wherein the configuration information further includes information indicating a scheduling gap between transport blocks. ### Claim 36 (depends on 35) The method of claim 35, wherein a scheduling gap between two consecutively transmitted transport blocks among the multiple transport blocks is configured based on the information indicating the scheduling gap.
