Abstract: The present specification provides a method for performing a radio link failure (RLF) recovery procedure in a wireless communication system.
The method performed by a first user equipment (UE) includes, wherein the first UE is connected to a base station via a UE-to-UMTS (Uu) link and is connected to a second UE via a sidelink, determining a path for performing the RLF recovery procedure when a RLF is detected on the Uu link, and performing an RRC connection re-establishment procedure in order to recover the RLF through the determined path.

Abstract: A method and apparatus for flexible resource configuration for unicast vehicle-to-everything (V2X) communication in new radio access technology (NR) is provided. The wireless is configured with a monitoring channel busy ratio (CBR) threshold and an entering CBR threshold. While performing sidelink transmission in a first transmission mode by using a third resource pool among at least one first resource pool for the first transmission mode, the wireless device measures a CBR of the third resource pool, and monitors at least one second resource pool for a second transmission mode based on that the CBR of the third resource pool is higher than the monitoring CBR threshold. Upon satisfying a condition related to the entering CBR threshold, the wireless device can perform sidelink transmission in the first transmission mode by using both the third resource pool and a fourth resource pool among the at least second resource pool.

Abstract: Provided are a method for a user equipment (UE) to transmit a medium access control protocol data unit (MAC PDU) in a wireless communication system, and an apparatus supporting the same. The method may include: allocating resource grants on multiple carriers; selecting a first carrier among the multiple carriers, based on allocated time of the resource grants; allocating a resource of the selected first carrier to a logical channel with the highest priority; and transmitting the MAC PDU, by using the resource of the selected first carrier.

Abstract: A method of performing a radio resource control (RRC) connection procedure of a relay user equipment (UE) in a wireless communication system is disclosed. The method includes, if a RRC connection procedure of a remote UE associated with the relay UE is triggered, receiving, from the remote UE, a first RRC establishment cause for a RRC connection of the remote UE; and if a RRC connection request of the relay UE is not allowed, transmitting, to a base station, a first RRC connection request including the first RRC establishment cause of the remote UE.

Abstract: A method for performing a sidelink communication through a terminal-to-network relay operation is disclosed. The method performed by a first user equipment (UE) includes transmitting, to a base station, a control message including indication information indicating whether a radio access technology (RAT) type of a radio interface section with a second UE is a 3GPP access or a non-3GPP access; receiving, from the base station, a radio resource for transmitting and receiving a signal with the second UE through the radio interface section; and transmitting and receiving the signal with the second UE based on the received radio resource.

Abstract: According to the present disclosure, a user equipment (UE) selects a carrier among a plurality of carriers, receives information on a channel busy ratio (CBR) threshold from a network, and triggers a carrier reselection. When a CBR of the carrier satisfies the CBR threshold, e.g. the CBR of the carrier is below than the CBR threshold, the UE keeps using the carrier. That is, the carrier reselection is not performed when the CBR of the carrier satisfies the CBR threshold. On the other hand, when a CBR of the carrier does not satisfy the CBR threshold, the UE performs the carrier reselection.

Abstract: A relay user equipment (UE) linked to a remote UE relays paging to the remote UE. The relay UE transmits paging frame (PF) information and paging occasion (PO) information to the remote UE. The relay UE receives a paging message for the remote UE in a PO of the remote UE or in a PO of the relay UE within a PF of the relay UE on the basis of the PF information and the PO information. The relay UE relays the paging message to the remote UE.
