1. A communication method using a non-orthogonal multiple access (NOMA) scheme by a terminal, the communication method comprising:
receiving, from a base station, configuration information about a transmission pattern assigned to the terminal, wherein the configuration information comprises at least one transmission pattern candidate set;
selecting a transmission pattern among the at least one transmission pattern candidate set based on at least one of an identifier of the terminal or a certain radio network temporary identifier (RNTI) corresponding to the terminal;
determining a terminal-specific transmission pattern per slot or resource block (RB) by which the terminal is configured to transmit data, by performing randomization based on the selected transmission pattern and at least one of an index of the slot or the RB;
processing the data to be transmitted in at least one of the slot or the RB, based on the determined terminal-specific transmission pattern; and
transmitting, to the base station, using the NOMA scheme, the processed data in the at least one of the slot or the RB.
