Abstract: The present disclosure relates to transmission prioritization in wireless communications. According to an embodiment of the present disclosure, a method performed by a wireless device in a wireless communication system comprises: configuring a threshold; creating a media access control (MAC) protocol data unit (MAC PDU) for sidelink comprising a MAC control element (CE); setting a priority value to the MAC CE; identifying a transmission of the MAC PDU for sidelink and an uplink transmission to be performed; determining that the transmission of the MAC PDU for sidelink and the uplink transmission are not able to be performed simultaneously; determining that the priority value of the MAC CE is lower than the threshold; prioritizing the transmission of the MAC PDU for sidelink over the uplink transmission; and performing the transmission of the MAC PDU for sidelink that is prioritized over the UL transmission.

Abstract: Disclosed are, according to various embodiments, a method for transmitting, by a user equipment (UE), a first collective perception message (CPM) in a wireless communication system supporting a sidelink, and an apparatus therefor. Disclosed are the method and the apparatus therefor, the method comprising the steps of: obtaining first object information on surrounding objects through a sensor; receiving a second CPM including second object information; and transmitting the first CPM including the first object information and location information for the UE, wherein the second CPM further includes information on a location reliability of the second object information, the position information of the UE is corrected by applying an offset, based on the first object information and the second object information being object information for the same object, and the offset is determined by applying a ratio between a first position reliability related to the position information of the UE and the second position reliability included in the second CPM to a distance between an object position based on the first object information and an object position based on the second object information.

Abstract: A method for performing wireless communication by a first device and a device for supporting same are provided. The method may comprise the steps of: receiving a physical sidelink shared channel (PSSCH) from a second device; determining a physical sidelink feedback channel (PSFCH) resource associated with the PSSCH; and transmitting hybrid automatic repeat request (HARQ) feedback to the second device on the PSFCH resource. Here, the PSFCH resource can be determined on the basis of a sub channel associated with the PSSCH, a slot associated with the PSSCH, a cast type of communication between the first device and the second device, an ID of the first device, and a source ID of the second device.
