Abstract: The present disclosure relates to logical channel prioritization (LCP) in wireless communications. According to an embodiment of the present disclosure, a method performed by a first wireless device in a wireless communication system comprises: creating a media access control (MAC) protocol data unit (PDU); and transmitting the MAC PDU to a second wireless device, wherein the MAC PDU includes at least one of data from sidelink control channel (SCCH), a MAC control element (CE) for sidelink (SL) feedback information, or data from sidelink transmission channel (STCH) according to a logical channel prioritization (LCP), wherein the data from SCCH including one or more PC5-signalling (PC5-S) messages has a higher priority to be included in the MAC PDU than the MAC CE for SL feedback information, and wherein the MAC CE for SL feedback information has a higher priority to be included in the MAC PDU than the data from STCH.

Abstract: Provided is a method for transmitting a signal by a terminal for vehicle-to-everything (V2X) communication in a wireless communication system and a terminal using the same method. The method comprises: mapping V2X data to a resource of a subframe including multiple symbols in a time domain; and transmitting the mapped V2X data to another terminal, wherein, in the step of mapping, resource elements included in a last symbol of the subframe are excluded.

Abstract: A method and apparatus for identification of control information for sidelink management in a wireless communication system is provide. A first wireless device (e.g., a first user equipment (UE)) receives control information including at least one identifier (ID) associated with a link, and determines one of in-sync indication or out-of-sync indication based on a receiving quality of the control information.

Abstract: A method of operating a Tx user equipment (UE) in a wireless communication system includes transmitting a random access preamble corresponding to a synchronization signal block (SSB) by the Tx UE, receiving a random access response in response to the random access preamble by the Tx UE, establishing a link with a Rx UE by the Tx UE, and transmitting a radio resource control (RRC) message based on sidelink radio link failure (RLF) to a base station (BS) by the Tx UE. The RRC message is related to reporting of the sidelink RLF to the BS, and includes a destination identifier (ID) related to the sidelink RLF.

Abstract: Provided are a method for operating a terminal for vehicle-to-everything (V2X) communication in a wireless communication system, and a terminal using the method. The method includes receiving data from another terminal, and transmitting an acknowledgment/negative-acknowledgment (ACK/NACK) for the data only when the distance to the another terminal is equal to or less than a predetermined value.

Abstract: Provided are a method for transmitting a signal by a terminal for vehicle-to-everything (V2X) communication in a wireless communication system, and a terminal using the method. The method comprises: performing first group transmission including first transmission and first retransmission; and performing second group transmission including second transmission and second retransmission, wherein the first group transmission and the second group transmission are performed to transmit data, and a resource reservation period for the first group transmission and the second group transmission is a half of a resource reservation period of another terminal which retransmits the data a maximum of only two times.
