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.

The disclosure provides a transmission method and device. The transmission method includes: receiving, by a user equipment, configuration information for indicating whether transmission of uplink control information on a first physical uplink shared channel is supported; and transmitting, by the user equipment, the first physical uplink shared channel and/or the uplink control information based on the configuration information.

Provided are a method by which a first device performs wireless communication an apparatus for supporting same. The method may comprise: receiving, from the base station through a physical downlink control channel (PDCCH), a downlink control information (DCI) related to the SL HARQ process ID, wherein the DCI includes information related to a second SL grant for retransmission of the MAC PDU and information related to a second PUCCH resource, wherein, based on the buffer related to the SL HARQ process ID being flushed, the first device does not transmit the MAC PDU to the second device based on the second SL grant, and the first device does not transmit SL HARQ feedback information related to the MAC PDU to the base station based on the second PUCCH resource.

A method and a device for transmitting a PPDU in a WLAN system are proposed. Specifically, an AP generates a PPDU and transmits the PPDU to a STA through a broadband. The PPDU includes an EHT-LTF and a data field. The data field includes a pilot tone. The coefficient of the pilot tone is set to a second pilot sequence in which a first pilot sequence is repeated. The first pilot sequence is {1 1 1 −1 −1 1 1 1}.
