Abstract: A method and apparatus for discontinuous reception (DRX) of downlink signal for sidelink transmission is provided. A wireless device operating in a wireless communication system monitors a physical downlink control channel (PDCCH) carrying a sidelink grant during an active time including a time interval for which a scheduling request (SR) is transmitted on a physical uplink control channel (PUCCH) and is pending, based on the SR being triggered for a sidelink buffer status report (SL BSR) and/or a sidelink channel state information (SL CSI) reporting.

Abstract: A method and apparatus for hybrid automatic repeat request (HARQ) feedback based on a communication range and location of devices is provided. A first device (e.g., receiving user equipment in sidelink) receives, from a second device (e.g., transmitting user equipment in sidelink, control information including 1) a communication range, and 2) a location of the second device. The first device determines whether to perform a hybrid automatic repeat request (HARQ) feedback based on whether a distance between a location of the first device for the control information and the location of the second device is smaller or equal to the communication range.

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: Provided are a method for performing sidelink transmission by a first device (100) in a wireless communication system, and a device for supporting same. The method comprises the steps of: determining a transport block size (TBS) on the basis of whether at least one of an automatic gain control (AGC) symbol and a guard period (GP) symbol is used for sidelink transmission; and performing the sidelink transmission with respect to a second device (200) on the basis of the determined TBS, wherein the AGC symbol may be a symbol which a first device (100) uses for AGC, and the GP symbol may be a symbol which the first device (100) uses for TX/RX switching.
