    Abstract: A method and an apparatus for transmitting/receiving feedback in a mobile communication system are provided. The method includes transmitting, to a terminal, CSI feedback configuration information including feedback mode information, and information on a codebook configuration and a CSI-RS configuration; and receiving, from the terminal, CSI feedback information including a CQI and a PMI based on the feedback mode information. The feedback mode information indicates types of CSI feedback information. The information on the codebook configuration and the CSI-RS configuration includes a set of available precoding matrices and a first number and a second number associated with antenna ports of CSI-RS. A number of the antenna ports of CSI-RS is determined based on the first number and the second number associated with the antenna ports. The PMI indicates a precoding matrix included in the set of available precoding matrices. The CQI is obtained based on the CSI-RS associated with the number of antenna ports.

    Abstract: The present disclosure relates to a communication technique for converging IoT technology with a 5G communication system for supporting a higher data transmission rate after a 4G system and, and a system therefor. The present disclosure can be applied to intelligent services on the basis of 5G communication technology and IoT-related technology (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail business, security and safety-related service, etc.). When a particular frequency at which an LTE-A system operates is included in an unlicensed band, a situation may occur where some subframes of the LTE-A system cannot be used. When a synchronization signal and a discovery reference signal to be transmitted by a base station collide with a detection and channel occupation operation for the unlicensed band, the timing of the detection and channel occupation operation for the unlicensed band may be adjusted in order to solve the problem of the collision.
