Abstract: Disclosed are a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. The disclosure can be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. According to an embodiment of the present invention, a method by which a base station transmits a signal in a wireless communication system comprises the steps of: transmitting, to a terminal through at least one beam, at least one beam index including information on beam direction; receiving, from the terminal, a preferred beam index determined by the terminal; determining a channel matrix between the base station and the terminal on the basis of the preferred beam index; and allowing the base station to transmit a signal to the terminal on the basis of the channel matrix. The study has been performed under the support of the “Government-wide Giga KOREA Business” of the Ministry of Science, ICT and Future Planning.

Abstract: A pre-5th-Generation (5G) or 5G communication system is provided for supporting higher data rates than in 4th-Generation system. An apparatus of a base station includes: at least one transceiver and at least one processor operatively connected to the transceiver. The transceiver receives channel quality information from a terminal. The processor obtains a first modulation and coding scheme (MCS) level and a number of first resource blocks based on the channel quality information, determines a power boosting value for applying a second MCS level indicating a higher modulation order or a higher code rate than the first MCS level, obtains, based on the power boosting value, a number of second resource blocks corresponding to a transport block size (TBS) value greater than a TBS value corresponding to the number of the first resource blocks in the first MCS level and transmits downlink data based on these determinations.
