    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 method for converging an IoT technology with a 5G communication system for supporting a higher data transfer rate beyond the 4G system; and a system therefor. The disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail business, security and safety services, etc.), based on 5G communication technologies and IoT-related technologies. A method and terminal are provided. The method includes receiving first sidelink control information (SCI) and first data corresponding to the first SCI, the first SCI including first priority information, receiving second SCI and second data corresponding to the second SCI, the second SCI including second priority information, identifying whether first feedback information associated with the first data or second feedback information associated with the second data is transmitted based on the first priority information or the second priority information when a resource for the first feedback information and a resource for the second feedback information are overlapped, and transmitting one of the first feedback information or the second feedback information which is associated with higher priority.

    Abstract: The disclosure relates to a method and apparatus by which a transmission terminal allocates resources in a vehicle-to-everything (V2X) system. An operating method of a terminal in a wireless communication system may include identifying a first candidate resource set for sidelink communication in a first resource selection window, through sensing based on first sidelink control information (SCI) received in a first sensing window, identifying a second candidate resource set for sidelink communication in a second resource selection window, through sensing based on second SCI received in a second sensing window, determining, based on the second SCI, whether to perform pre-emption or re-evaluation for a first resource, and when it is determined to perform the pre-emption or the re-evaluation for the first resource, triggering re-selection of resources for sidelink communication, and reporting the first resource for which the pre-emption or the re-evaluation has been performed, and the second candidate resource set to a higher layer of the terminal.
