Abstract: Provided are a method for transmitting a relay signal for V2X communication in a wireless communication system and a device using the same. Specifically, a terminal receives allocation information of a first relay resource and a second relay resource for a communication group from a base station. A first terminal receives a data signal through a reception beam for the first relay resource from a second terminal. The first terminal transfers the data signal to a third terminal through a transmission beam for the first relay resource. Further, the first terminal transmits an ACK/NACK for the data signal to the second terminal through a transmission beam for the second relay resource. The reception beam for the first relay resource is symmetrical to the transmission beam for the second relay resource. The transmission beam for the first relay resource is symmetrical to a reception beam for the second relay resource.

Abstract: Provided are a method for transmitting uplink control information (UCI) of a terminal in a wireless communication system and the UE using the method. The method includes determining a number of coded symbols for the UCI transmission and transmitting the UCI on a physical uplink shared channel (PUSCH) based on the number of coded symbols. The number of coded symbols is determined among a first value based on a payload size of the UCI and an offset value and a second value based on a radio resource control (RRC) signal.
