1. A method of transmitting data by a base station in a wireless communication system, the method comprising:
transmitting a reference signal (RS) to one or more user equipments (UEs);
receiving channel quality indication (CQI) information based on reception of the RS from the one or more UEs;
determining a modulation and coding scheme (MCS) level based on the CQI information;
transmitting data to the one or more UEs in relation to the MCS level; and
receiving acknowledgement/negative acknowledgement (ACK/NACK) for the transmitted data,
wherein the MCS level is determined based on the CQI information and on an offset determined according to a machine learning process, and
wherein the machine learning process for determining the offset is performed by setting any one selected from among a plurality of MCS offset values to an operation value of machine learning, setting an error rate for the operation value to a state value of the machine learning, and setting a processing rate at a level at which the error rate satisfies a predetermined criterion to a reward value of the machine learning process.
