Abstract: Provided are a method for transmitting downlink control information for sidelink scheduling in a wireless communication system and a wireless apparatus using the method. The method is characterized by: generating sidelink SPS activation/release DCI for indicating sidelink semi-persistent scheduling (SPS) activation or release; and transmitting the sidelink SPS activation/release DCI to a terminal, wherein the sidelink SPS activation/release DCI further comprises a sidelink SPS activation/release field and a sidelink SPS configuration index field not present in sidelink dynamic DCI which is for dynamically scheduling the sidelink.

Abstract: According to the present invention, a user equipment (UE) calculates its paging occasion based on a specific beam to monitor paging. In detail, the UE selects at least one beam among multiple beams, calculates a paging occasion consisting of the at least one beam, and monitors a paging in the paging occasion. When the paging occasion consists of the multiple beams including the at least one beam, the paging may be monitored in a part of the paging occasion where the at least one beam is transmitted. Alternatively, when the paging occasion only consists of the at least one beam, the paging may be monitored in all of the paging occasion where the at least one beam is transmitted.

Abstract: Provided is a cell reselection method performed by a terminal in a wireless communication system. The method includes: receiving first priority information for at least one frequency; receiving second priority information for the one or more frequencies; and selectively applying, based on the state of the terminal, any one of the first priority information and second priority information and performing cell reselection. The first priority information is provided through a connection rejection message and provides instructions on the priority for the one or more frequencies to be lowered. The second priority information is provided from a current cell through system information.

Abstract: In a wireless communication system, a user equipment (UE) may reselect a sidelink resource to be used for vehicle-to-everything (V2X) communication. The reselection of sidelink resource may be triggered by various conditions. In particular, the reselection of the sidelink resources may be triggered when a value of sidelink resource reselection counter is zero. More specifically, the UE determines that data for the V2X communication is available in a sidelink traffic channel (STCH), determines that a value of the sidelink resource reselection counter is zero, and reselects the sidelink resources.

Abstract: The present application provides a method for transmitting or receiving a sidelink signal by a terminal in a wireless communication system. Specifically, the method for transmitting or receiving a sidelink signal comprises the steps of: transmitting a first sidelink signal during a transmission period by using a transmission resource selected among resource units included in a first transmission resource pool; monitoring resource units included in a second transmission resource pool; and transmitting a second sidelink signal during the transmission period by using a selected transmission resource on the basis of a result of the monitoring among the resource units included in the second transmission resource pool when a resource pool changes from the first transmission resource pool to the second transmission resource pool, wherein the second transmission resource pool is included in a reception resource pool corresponding to the first transmission resource pool.
