Resource mapping method for transmission and reception of data in wireless communication system and apparatus therefor

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.

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.
