Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for receiving handover assistance information including a list of one or more candidate target cells; initiating a first random access procedure to a first candidate target cell of the one or more candidate target cells and a first timer for the first candidate target cell, when the first candidate target cell satisfies a handover condition; and stopping trying to connect to the first candidate target cell when any one of at least the following events occurs: (i) the first timer expires for the first candidate target cell, and (ii) a number of random access trials to the first candidate target cell reaches a maximum number.

Abstract: The present invention relates to a wireless communication system and, specifically, to a method and an apparatus therefor, the method comprising: a step of configuring a plurality of carriers to which an SL communication is applied, wherein an SL resource pool is periodically configured in each carrier; a step of selecting one of the plurality of carriers as a serving carrier; a step of selecting a transmission resource among the SL resource pool in the selected carrier; and a step of transmitting the SL signal using the transmission resource, wherein a frequency of a process of reselecting the serving carrier is less than a frequency of a process of reselecting the transmission resource among the SL resource pool in the preselected carrier.

Abstract: A method and apparatus for continuing transmission while in leaving a connected state with a network in wireless communication system is provided. A wireless device leaves a connected state with the network. The wireless device performs transmission with a configured grant in a validity area, wherein the configured grant is received from the network and mapped to the validity area, while in leaving the connected state. The wireless device performs a random access to the network, after the wireless device leaves the validity area.

Abstract: A method for receiving broadcast information by a user equipment (UE) connected with a network via a relay UE in a wireless communication system is disclosed. The method includes steps of determining whether the broadcast information stored in the UE is updated or not; transmitting a request message for updating the broadcast information to the relay UE, when the broadcast information stored in the UE is not updated; and receiving the requested broadcast in¬formation from the relay UE or the network.

Abstract: A method and apparatus for sidelink connection request based on congestion level for establishing a direct connection between wireless devices is provided. A first wireless device triggers a signaling procedure based on a congestion level of at least one carrier, selects a carrier among the at least one carrier, and transmits a message in the signaling procedure on the selected carrier. Upon receiving the message, a second wireless device may perform carrier reselection.
