    Abstract: A method performed by a terminal in a wireless communication system is provided. The method includes obtaining information on transmission parameters associated with a SL positioning reference signal, identifying a resource pool associated with the SL positioning reference signal, performing a measurement based on the resource pool associated with the SL positioning reference signal, and determining at least one transmission parameter associated with the SL positioning reference signal based on the measurement and the information on the transmission parameters. The transmission parameters include at least one of a comb size associated with the SL positioning reference signal or a number of symbols for the SL positioning reference signal in a slot.

    Abstract: The present disclosure relates to: a communication technique merging IoT technology with a 5G communication system for supporting a data transmission rate higher than that of a 4G system; 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, security- and safety-related services, and the like), emergency communication services (emergency rescue signal transmission services), and the like on the basis of 5G communication technology, IoT-related technology and satellite communication. Proposed in the present disclosure is a method for performing a correlation operation on the basis of a reception signal and a PRACH preamble, and estimating a frequency offset on the basis of a first peak value and/or a second peak value in accordance with the correlation operation result.

    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.
