In a wireless communication system, a base station apparatus may include at least one transceiver, and at least one processor operatively coupled with the at least one transceiver. The at least one transceiver may transmit, to a terminal, configuration information associated with a primary beam and a secondary beam. The processor may determine the primary beam and the secondary beam based on feedback information regarding beams of the base station, received from the terminal. The at least one transceiver may be configured to transmit, to the terminal, indication information for identifying the primary beam and the secondary beam, perform communication with the terminal by using the primary beam, and perform communication with the terminal by using the primary beam and the secondary beam based on a determination of a change of a communication state for the primary beam.

Abstract: Disclosed are a method and an apparatus for channel quality estimation in consideration of interference control and coordinated communication in a cellular system. A base station receives an SRS transmitted by a terminal to thus measure received power, and then configures, for the terminal, a CSI process which may measure SINRs for base stations having higher SRS received power. If the terminal feeds back, to the base station, channel quality information for the configured CSI process, the base station determines an SINR and a MCS to be applied to data transmission in consideration of a received CQI and a CoMP transmission scheme, and applies the determined SINR and MCS to thus transmit data.
