Abstract
Provided is a method and device for transmitting uplink data by using a non-orthogonal code multiple access scheme in a wireless communication system. Specifically, a terminal supporting multiple layers receives an NoMA MCS index from a base station. The NoMA MCS index is selected from an NoMA MCS table on the basis of the quality of an uplink channel. The NoMA MCS table is defined in advance as a table including the NoMA MCS index, the number of multiple layers, and a modulation order. The number of multiple layers is determined according to the NoMA MCS index. The terminal transmits the uplink data configured on the basis of the NoMA MCS index, via the multiple layers.

A method of transmitting uplink (UL) data in a wireless communication system to which a non-orthogonal multiple access (NoMA) scheme is applied, the method comprising:
- receiving, by a terminal supporting multi-layers, a NoMA modulation and coding scheme (MCS) index from a base station,
- wherein the NoMA MCS index is selected from a NoMA MCS table based on quality of a UL channel, the NoMA MCS table is pre-defined as a table including the NoMA MCS index, the number of multi-layers, and a modulation order, and the number of multi-layers is determined based on the NoMA MCS index;
- and
- transmitting, by the terminal, the UL data configured based on the NoMA MCS index through the multi-layers.
A terminal for transmitting uplink (UL) data and supporting multi-layers in a wireless communication system to which a non-orthogonal multiple access (NoMA) scheme is applied, the terminal comprising:
- a transceiver transmitting and receiving a radio signal;
- and
- a processor coupled to the transceiver, wherein the processor is configured to:
- receive a NoMA modulation and coding scheme (MCS) index from a base station, wherein the NoMA MCS index is selected from a NoMA MCS table based on quality of a UL channel, the NoMA MCS table is pre-defined as a table including the NoMA MCS index, the number of multi-layers, and a modulation order, and the number of multi-layers is determined based on the NoMA MCS index;
- and
- transmit the UL data configured based on the NoMA MCS index through the multi-layers.
