Abstract: According to an embodiment of the present disclosure, a method of a first User Equipment (UE) for transmitting information related to an Inter-UE Coordination in a wireless communication system includes: determining information related to an Inter-UE Coordination based on configuration information, and transmitting, to a second UE, the information related to the Inter-UE Coordination. The information related to the Inter-UE Coordination is based on information representing a preferred resource or information representing a conflict of a reserved resource. Based on information for a first condition included in the configuration information, the preferred resource is determined among the resources related to the transmission of the second UE. Based on the information for the second condition included in the configuration information, an RSRP threshold related to the RSRP measured by the first UE is determined.

Abstract: A method for transmitting uplink control information and an apparatus therefor are disclosed. In a method for transmitting uplink control information using a physical uplink shared channel (PUSCH) in a wireless communication system, the method is performed by a terminal and includes receiving downlink control information including an accumulated number of physical downlink shared channels (PDSCH) transmissions associated with a cell group configured for the terminal, coding the uplink control information using the accumulated number of PDSCH transmissions, and transmitting the coded uplink control information using the PUSCH.

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: A method of operating a first device 100 in a wireless communication system is proposed. The method may comprise: generating a MAC PDU related to a groupcast transmission; and selecting at least one SL resource for a transmission of the MAC PDU among a plurality of candidate resources in a resource pool, wherein a first SL resource included in the at least one SL resource is included in a first SL DRX active time, and the first SL resource being selected outside the first SL DRX active time is not allowed, based on the MAC PDU being related to groupcast transmission.

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 in which a first device performs wireless communication, and a device supporting same. The method can comprise the steps of: deciding first power for physical sidelink shared channel (PSSCH) transmission in a second symbol duration; deciding second power for physical sidelink control channel (PSCCH) transmission in a first symbol interval on the basis of the first power; performing the PSCCH transmission to a second device in the first symbol duration on the basis of the second power; and performing the PSSCH transmission to the second device in the second symbol duration on the basis of the first power. The second symbol duration can comprise resources for the PSSCH transmission. The first symbol duration can comprise resources for the PSCCH transmission and the PSSCH transmission.

Abstract: A method for performing wireless communication by a first apparatus and an apparatus for supporting same are provided. The method may comprise the steps of: receiving a physical sidelink control channel (PSCCH) from a second apparatus; receiving a physical sidelink shared channel (PSSCH) related to the PSCCH from the second apparatus; determining a physical sidelink feedback channel (PSFCH) resource related to the PSSCH, on the basis of a slot and sub-channel related to the PSSCH; and obtaining a channel busy ratio (CBR) value related to PSFCH transmission on the PSFCH resource. The CBR value may be obtained on the basis of (i) a first slot before a first offset from a slot that received the PSSCH related to the PSFCH resource, and (ii) measurement in a time section between the first slot and a second slot before a second offset.
