Abstract: Provided is a method for transmitting a signal by means of a sidelink terminal in a wireless communication system, according to an embodiment of the present invention. The method for transmitting a signal comprises the steps of: selecting any one of an eNB and a gNB as a synchronization reference; and transmitting a sidelink channel/signal including an SSB (SS/PBCH block) on the basis of synchronization of the base station selected as the synchronization reference, wherein when dual connectivity (DC) is configured for the terminal, the terminal selects a master NB (NodeB) among the eNB as the synchronization reference. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, the BS or a network.

Abstract: A method and an apparatus for sidelink of a wireless communication system are proposed. The present disclosure proposes an example in which a TX UE or a RX UE sets a length of an ACK/NACK signal adaptively. The TX UE may set the length of the ACK/NACK signal based on various elements such as priority, length, and service coverage of sidelink data, and the RX UE may set the length of the ACK/NACK signal based on various elements obtained from a process for receiving the sidelink data.

Abstract: The present application discloses a method for allocating resources for direct communication between terminals in a wireless communication system. Specifically, the method for allocating resources comprises: a step of configuring a first periodic resource so as to transmit multiple messages via direct communication between the terminals; and a step of transmitting the multiple messages by using the first periodic resource if a coding rate corresponding to the first periodic resource is below a maximum coding rate configured by an upper layer, wherein, if the coding rate is equal to or above the maximum coding rate, the first periodic resource is released and a second periodic resource is configured.
