Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for forwarding system information for a remote UE by a relay UE in wireless communication system, the method comprising: establishing a link between a remote UE and the relay UE for communicating between the remote UE and the network via the relay UE; receiving assistance information including a serving cell identity of the remote UE from the remote UE; checking whether a serving cell identity of the relay UE and the serving cell identity of the remote UE are same or not; and forwarding system information block (SIB), which was already received by the relay UE from the network, to the remote UE via the link if the serving cell identity of the relay UE and the serving cell identity of the remote UE are different. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

Abstract: The present invention relates to uplink signal transmission by a user equipment (UE) in terms of timing advance value in a wireless communication system. According to an embodiment of the invention, the UE applies a predetermined timing advance value for a TAG (Timing Advance Group) if the TAG includes only one or more first type cells. Here, a random access procedure is not supported on the first type cells. Based on it, the UE transmits the uplink signals to the network on one of the first type cells based on the timing advance value applied for the TAG.

Abstract: A method and apparatus for performing a cell selection triggered by a lower layer signaling in a wireless communication system is provided. A first node receives information for triggering a connection reestablishment, i.e. the lower layer signaling, from a second node. The first node deprioritizes a serving cell based on the information for the triggering the connection reestablishment, and after deprioritizing the serving cell, selects a cell other than the serving cell. The first node performs uplink (UL) transmission on the selected cell for the connection reestablishment.

Abstract: The present invention provides a method and apparatus for performing device-to-device communication in a wireless communication system. The method includes generating identification information of a D2D user equipment that supports the D2D communication as identification information for D2D discovery using a hash function, the identification information for discovery includes information of a first length for indicating a division region of the beacon signals and information of a second length included in the beacon. The information of a first length and the information of a second length are smaller than identification information of the D2D user equipment. Accordingly, by performing discovery for the D2D user equipment through the identification information having shorter length than prior art, and performing discovery in a range where the discovery is available through the region in which the beacon signals are allocated, advantages of performing the D2D discovery effectively are provided.

Abstract: Proposed is a method for a first device to perform wireless communication. The method may comprise the steps of: establishing a connection with a second device; and reselecting a cell on the basis that the first device is in a radio resource control (RRC) IDLE state or an RRC INACTIVE state. For example, a priority related to cell reselection can be set such that a cell related to a new radio (NR) has a high priority. For example, cell reselection can be performed first on the cell related to the NR on the basis of the priority related to cell reselection.

Abstract: A method and apparatus for Sidelink (SL) Discontinuous Reception (DRX) operation based on resource allocation is provided. A first wireless device, e.g., receiving user equipment (RX UE), monitors first Physical Sidelink Control Channel (PSCCH) transmissions from a second wireless device, e.g., transmitting UE (TX UE), in a Sidelink (SL) active time for SL Discontinuous Reception (DRX). The first wireless device receives, from the second wireless device, an indication to reselection of sidelink resources, and adjusts the SL active time based on the indication. The first wireless device monitors second PSCCH transmissions from the second wireless device in the adjusted SL active time.
