Abstract: Disclosed is a method for a first terminal, which supports a sidelink, to transmit signals in a wireless communication system. Specifically, the method may comprise: a step for receiving a sidelink synchronization signal (SLSS) from a second terminal; a step for acquiring information about a subframe boundary time point for timing synchronization, and information about a propagation delay time; and a step for transmitting a sidelink signal to the second terminal on the basis of the subframe boundary time point and a timing advance (TA) that is twice the length of the propagation delay time.

Abstract: Provided are a method for transmitting a vehicle-to-everything (V2X) signal performed by a user equipment (UE) having a limited transmission capability in a multi-carrier system and a UE using the method. The method includes selecting a first resource in a first carrier, if using a specific subframe in a second carrier exceeds a transmission capability of the UE considering the first resource, selecting a second resource randomly among the remaining subframes except the specific subframe in the second carrier and transmitting the V2X signal using the first resource and the second resource.

Abstract: A method of performing wireless communication by a first device is proposed. The method includes receiving downlink control information (DCI) related to first sidelink from a base station, and transmitting, to the base station, a confirmation message for reception of the DCI related to the first sidelink through a first medium access control (MAC) control element (CE). For example, the first MAC CE may include at least one index information related to at least one semi-persistent scheduling (SPS) configuration activated or released by the DCI.

Abstract: One embodiment of the present specification suggests a method and an apparatus for supporting a plurality of carriers in a single UE. Each carrier can support V2X communication of various standards. The UE can perform an improved backoff operation for at least one carrier. The backoff operation applied to any one of the carriers can be performed on the basis of the operation of another carrier. For example, the backoff operation can be performed on the basis of whether or not a signal is received by the other carrier. The backoff operation based on the present specification can solve a technical problem which arises when different operations are performed in the plurality of carriers.
