obtaining resource allocation information by decoding the first control information and the second control information; and receiving the data from at least one of the first apparatus and the second apparatus, based on the resource allocation information, wherein the resource allocation information comprises information for resource regions comprising (i) a first resource region commonly allocated from the first apparatus and the second apparatus, and (ii) a second resource region allocated from one of the first apparatus and the second apparatus, and the data is mapped to at least one of the first resource region and the second resource region, on the basis of a resource mapping order set according to a transmission unit of the data. ## Claims ### Claim 1 A method for receiving data by a user equipment (UE) in a wireless communication system, the method comprising: receiving first control information and second control information; obtaining resource allocation information by decoding the first control information and the second control information; and receiving at least one of (i) first data scheduled by the first control information or (ii) second data scheduled by the second control information, based on the resource allocation information, wherein the resource allocation information includes information regarding resource regions including (i) a first resource region consisting of first time-frequency resources allocated by the first control information which are identical to second time-frequency resources allocated by the second control information and (ii) a second resource region consisting of third time-frequency resources allocated by one of the first control information or the second control information, wherein the second resource region does not overlap with the first resource region, and wherein at least one of the first data or the second data is mapped to at least one of the first resource region or the second resource region based on a resource mapping order configured based on a transmission unit of data. ### Claim 2 (depends on 1) The method of claim 1, wherein the transmission unit of the data is one of a code block, a code block group, or a transmission block. ### Claim 3 (depends on 2) The method of claim 2, wherein, based on the transmission unit of the data being the code block or the code block group, the data is mapped in order of a layer, a frequency domain of the first resource region, a time domain of the first resource region, and the second resource region. ### Claim 4 (depends on 2) The method of claim 2, wherein, based on the transmission unit of the data being the transmission block, at least one of the first data or the second data is mapped in order of a layer, order of the first resource region and the second resource region, a frequency domain, and a time domain. ### Claim 5 (depends on 4) The method of claim 4, wherein resources of the first resource region and resources of the second resource region are mapped to each other at a ratio of one-to-one. ### Claim 6 (depends on 4) The method of claim 4, wherein resources of the first resource region and resources of the second resource region are mapped to each other at a ratio of 1 to N. ### Claim 7 (depends on 6) The method of claim 6, wherein the N value is calculated based on a number of resource blocks in the first resource region and a number of resource blocks in the second resource region. ### Claim 8 (depends on 6) The method of claim 6, wherein physical resource blocks (PRBs) of the first resource region and the second resource region are intersected to be mapped to a virtual resource block (VRB). ### Claim 9 (depends on 2) The method of claim 2, wherein, based on the transmission unit of the data being the transmission block, the first control information and the second control information include at least one of a rank, a demodulation reference signal (DMRS) port, or a modulation and coding scheme (MCS), to be applied to the transmission block. ### Claim 10 (depends on 1) The method of claim 1, wherein the first control information includes a specific value used, based on reception of the second control information being failed. ### Claim 11 (depends on 10) The method of claim 10, further comprising: performing blind detection on resource blocks corresponding to a multiple of the specific value in a resource region allocated based on the first control information based on the reception of the second control information being failed. ### Claim 12 (depends on 11) The method of claim 11, wherein the blind detection is performed from resource blocks having a low resource block index in the resource region allocated based on the first control information. ### Claim 13 A user equipment (UE) configured to receive data in a wireless communication system, the UE comprising: one or more transceivers; one or more processors; and one or more memories that store instructions, based on being executed by the one or more processors, configure the one or more processors to perform operations comprising: receiving first control information and second control information; obtaining resource allocation information by decoding the first control information and the second control information; and receiving at least one of (i) first data scheduled by the first control information or (ii) second data scheduled by the second control information based on the resource allocation information, wherein the resource allocation information includes information regarding resource regions including (i) a first resource region consisting of first time-frequency resources allocated by the first control information which are identical to second time-frequency resources allocated by the second control information and (ii) a second resource region consisting of third time-frequency resources allocated by one of the first control information or the second control information, wherein the second resource region does not overlap with the first resource region, and wherein at least one of the first data or the second data is mapped to at least one of the first resource region or the second resource region based on a resource mapping order configured based on a transmission unit of data. ### Claim 14 (depends on 13) The UE of claim 13, wherein, based on the transmission unit of the data being a code block or a code block group, at least one of the first data or the second data is mapped in order of a layer, a frequency domain of the first resource region, a time domain of the first resource region, and the second resource region. ### Claim 15 An apparatus configured to operate in a wireless communication system, the apparatus comprising: one or more memories storing instructions; and one or more processors configured to execute the instructions to perform operations comprising: receiving first control information and second control information; obtaining resource allocation information by decoding the first control information and the second control information; and receiving at least one of (i) first data scheduled by the first control information or (ii) second data scheduled by the second control information, based on the resource allocation information, wherein the resource allocation information includes information regarding resource regions including (i) a first resource region consisting of first time-frequency resources allocated by the first control information which are identical to second time-frequency resources allocated by the second control information and (ii) a second resource region consisting of third time-frequency resources allocated by one of by the first control information or the second control information, wherein the second resource region does not overlap with the first resource region, and wherein at least one of the first data or the second data is mapped to at least one of the first resource region or the second resource region based on a resource mapping order configured based on a transmission unit of data.
