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.

Abstract: The present disclosure relates 5G or pre-5G communication systems for supporting higher data transmission rate than those by LTE or other post-4G communication systems. According to the present disclosure, a method for operating a beamformed reference signal by a base station and terminal in a communication system, and the terminal, are provided. The method includes transmitting, to a terminal, control information indicating whether a first codebook is used for generating feedback information on a downlink reference signal. The first codebook is used if generating feedback information on the beamformed reference signal and is generated based on a number of antenna ports and a number of ranks.

Abstract: Disclosed is a 5G or pre-5G communication system to be provided so as to support a data transmission rate higher than that of a 4G communication system, such as LTE. Disclosed is a communication method of a base station using a channel state information reference signal (CSI-RS) in a mobile communication system, the method comprising the steps of: receiving a sounding reference signal (SRS) from a terminal; selecting a precoding matrix by using the received SRS; transmitting a CSI-RS by using the selected precoding matrix; receiving a CSI report from the terminal, and determining a transmission parameter on the basis of the CSI report; and transmitting data to the terminal by applying the determined transmission parameter thereto, wherein the CSI-RS is aperiodically transmitted.

Abstract: Disclosed are: a communication technique for fusing, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G communication system; and a system therefor. The communication technique can be applied, on the basis of 5G communication technology and IoT-related technology, to intelligent services (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). A method for estimating a channel in a communication system, according to one embodiment of the present invention, comprises the steps of: confirming a code and antenna distinguishing scheme used in channel estimation; generating a channel estimation code on the basis of the confirmed code and antenna distinguishing scheme; and transmitting the generated channel estimation code through a plurality of transmission antennas.
