    Abstract: The present disclosure relates to a communication technique for convergence of a 5G communication system for supporting a higher data transmission rate beyond a 4G system with an IoT technology, and a system therefor. The present disclosure may be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety-related service, etc.) on the basis of a 5G communication technology and an IoT-related technology. The present invention relates to a method of a wireless communication system, the method comprising the steps of: receiving at least one piece of quasi co-location (QCL) configuration information including information indicating a plurality of CSI-RS resources from a base station; receiving downlink control information (DCI) including an indicator indicating one of the at least one piece of QCL configuration information; estimating channel state information on the basis of at least one CSI-RS resource among the plurality of CSI-RS resources; and receiving downlink data on the basis of the channel state information, wherein the plurality of CSI-RS resources include at least one among a periodic CSI-RS resource, a semi-persistent CSI-RS resource, and an aperiodic CSI-RS resource.

    Abstract: The disclosure relates to a communication technique for convergence of a 5G communication system for supporting a higher data transmission rate beyond a 4G system with an IoT technology, and a system therefor. The disclosure may be applied to an intelligent service (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security- and safety-related service, etc.) on the basis of a 5G communication technology and an IoT-related technology. A method is provided for receiving a CSI-RS. The method includes acquiring, by a UE, a configuration for a resource set including a resource set identifier, information for at least one CSI-RS resource, and repetition information, wherein a number of the at least one CSI-RS resource is up to a maximum number of CSI-RS resources per resource set, and the repetition information is set as either on or off; acquiring, by the UE, a CSI-RS resource configuration per CSI-RS resource including a CSI-RS resource identifier, information for a number of CSI-RS ports, and information for an OFDM symbol; acquiring, by the UE, from the base station, a CSI report configuration including information for reporting parameters and information for a reporting method, wherein the information for the reporting parameters indicates at least one of a CRI, a RI, a PMI, or a CQI, and the information for the reporting method corresponds to periodic, semi-persistent, or aperiodic; and transmitting, by the UE, to the base station, CSI based on the configuration for the resource set and the CSI report configuration.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system with a technology for Internet of Things (IoT). Methods and apparatuses are provided in which first sidelink data and second sidelink data are received from one or more terminals. It is determined whether a first resource for transmitting first feedback information for the first sidelink data and a second resource for transmitting second feedback information for the second sidelink data overlap each other. When the first resource and the second resource overlap each other, feedback information corresponding to one of the first feedback information and the second feedback information having a higher priority, is transmitted to the one or more terminals. A priority of each of the first feedback information and the second feedback information is based on sidelink control information scheduling each of the first sidelink data and the second sidelink data.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method by a first terminal in a wireless communication system is provided. The method includes determining whether to transmit a preamble for an automatic gain control (AGC), determining a slot and at least one symbol in the slot to transmit the preamble for the AGC, in a case in which it is determined to transmit the preamble for the AGC, and transmitting, to a second terminal, the preamble for the AGC in the determined slot and the at least one symbol in the slot.
