Abstract:
The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transfer rate beyond a 4G communication system such as LTE. A method and an apparatus for transmitting and receiving channel state information are disclosed. The method comprises: a step of transmitting, to a terminal, a signaling message including first information indicating at least one precoding matrix which is applicable to a symbol vector to be transmitted; a step of transmitting, to the terminal, a channel status information-reference signal (CSI-RS) for the terminal; and a step of receiving channel state information including a channel quality indicator (CQI) which is calculated using the selected precoding matrix on the basis of second information from the terminal.
