Method and device for transmitting/receiving data using transport block size defined for machine type communication terminal in wireless access system supporting machine type communication

A machine type communication (MTC) user equipment (UE) in a wireless communication system, the MTC UE comprising:

• a memory;
• and,
• at least one processor coupled with the memory,
• wherein the at least one processor is configured to:
• receive information related to a repetition number,
• wherein the repetition number is related to a coverage enhancement (CE) of the MTC UE;
• receive modulation and coding scheme (MCS) information on an MCS index and resource allocation information;
• and
• receive data repeatedly based on the repetition number and a transmission block size (TBS),
• wherein the TBS is determined based on a TBS index and the resource allocation information,
• wherein the TBS index is determined based on the MCS index,
• wherein the TBS index is within a predetermined range,
• wherein the predetermined range is configured to a part of TBS indexes, from 0 to 9, included in a TBS table, and
• wherein the TBS table is configured to support a legacy UE.

A base station in a wireless communication system, the base station comprising:

• a memory;
• and,
• at least one processor coupled with the memory,
• wherein the at least one processor is configured to:
• transmit, to a machine type communication (MTC) user equipment (UE), information related to a repetition number,
• wherein the repetition number is related to a coverage enhancement (CE) of the MTC UE;
• transmit, to the MTC UE, modulation and coding scheme (MCS) information on an MCS index and resource allocation information;
• and
• transmit, to the MTC UE, data repeatedly based on the repetition number and a transmission block size (TBS);
• wherein the TBS is related to a TBS index and the resource allocation information,
• wherein the TBS index is related to the MCS index,
• wherein the TBS index is within a predetermined range,
• wherein the predetermined range is configured to a part of TBS indexes, from 0 to 9, included in a TBS table, and
• wherein the TBS table is configured to support a legacy UE.
