    Abstract: The present disclosure relates to: a communication technique combining a 5G communication system, for supporting a higher data transfer rate than 4G systems, with IoT technology; and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail businesses, security and safety-related services, etc.) on the basis of 5G communication technology and IoT-related technology. According to an embodiment of the present invention, a method of a terminal side link communication is characterized by further comprising: determining a first path attenuation between a second terminal and a first terminal; determining a second path attenuation between a base station and the first terminal; determining the transmission power of the first terminal based on at least one among the first pathloss and the second pathloss; and transmitting a signal based on the transmission power of the first terminal.

    Abstract: Disclosed are a communication technique for merging, with an IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. The disclosure can be applied 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) on the basis of 5G communication technology and IoT related technology. A new radio access technology (NR) system, which is novel 5G communication, is designed such that various services can be freely multiplexed in time and frequency resources, thereby enabling channel state information based on an aperiodic CSI-RS or a synchronization signal to be transmitted and received. According to the present invention, a base station in a wireless communication system transmits channel state information reference signal (CSI-RS) configuration information to a terminal, transmits channel state information feedback configuration information to the terminal, transmits CSI-RS trigger information to the terminal, aperiodically transmits a CSI-RS to the terminal according to the CSI-RS trigger information, and can receive, from the terminal, channel state information generated on the basis of the transmitted CSI-RS, wherein the CSI-RS is configured according to the CSI-RS configuration information, and at least a part of the configured CSI-RS can be transmitted by the CSI-RS trigger information.

    Abstract: A method, performed by a user equipment (UE), in a wireless communication system is provided. The method includes receiving information on a number of physical resource blocks (PRBs), determining a valid number of PRBs based on the information in case that a transform precoding is configured, and transmitting a physical uplink shared channel (PUSCH) based on the valid number of PRBs, wherein in case that the number of PRBs based on the information does not satisfy a pre-defined rule associated with the transform precoding, the valid number of PRBs corresponds to the largest integer satisfying the pre-defined rule associated with the transform precoding which is not greater than the number of PRBs based on the information.

    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.
