Provided is a method of performing, by a user equipment (UE), wireless communication in a wireless communication system, the method including generating a first message and transmitting the generated first message. Here, a transmission format for transmitting the first message may be determined depending on whether transmission profile (Tx profile) information is transmitted from an upper layer of the UE.

Method and apparatus for performing wireless communication in wireless communication system supporting vehicle communication

The present disclosure can provide a method in which a terminal performs transmission in a wireless communication system. The method for performing transmission can comprise the steps in which: a terminal receives a plurality of pre-configured resources; the device confirms as to whether the plurality of pre-configured resources collide; the terminal selects any one pre-configured resource among a plurality of collided pre-configured resources; and transmission for the selected preconfigured resource is performed.

Method and apparatus for supporting a plurality of configured grants in wireless communication system

Sidelink downlink control information (SL DCI) associated with transmission of one or more sidelink signals may be communicated. A wireless user device may transmit, based on the SL DCI and to one or more second wireless user devices, the one or more sidelink signals via a first quantity of sidelink channel resources. The wireless user device may receive first sidelink HARQ feedback information responsive to the one or more sidelink signals. The wireless user device may determine, based on a sidelink HARQ feedback timing, a time interval to transmit the first sidelink HARQ feedback information. The wireless user device may determine, based on the first quantity, a sidelink HARQ codebook. The wireless user device may transmit, during the time interval, based on the sidelink HARQ codebook, and to the base station, an uplink signal indicating the first sidelink HARQ feedback information.

Method and apparatus for using HARQ in wireless communications

Provided is a method and apparatus for performing a random access procedure. A wireless device may transmit a random access preamble and may monitor for a random access response. The wireless device may determine to transmit a second random access preamble or to transmit uplink data responsive to the random access response. A time for preparing the second random access preamble may be determined based on a subcarrier spacing associated with the random access preamble or a subcarrier spacing associated a downlink channel associated with the random access response. A time for preparing the uplink data may be determined based on a subcarrier spacing associated with the uplink data or a subcarrier spacing associated a downlink channel associated with the random access response.

Apparatus and method for performing random access in wireless communication system

The present disclosure provides a method for performing HARQ retransmission by a terminal supporting V2X communication in a wireless communication system. The method for performing HARQ retransmission may comprise the steps of: transmitting data by a transmission terminal in a pre-configured resource; receiving, by the transmission terminal, a NACK response to the data from a reception terminal; and retransmitting the data by the transmission terminal after changing an NDI value based on a resource dynamically allocated from a base station.
