Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing management of different IDs in a Relay UE in wireless communication system, the method comprising: receiving information for mapping table between a set of first identifiers (IDs) and a set of second IDs from a network; receiving a UL packet, which is to be forwarded to the network, without a second ID from the remote UE identified by a first ID associated with the second ID according to the mapping table; adding the second ID associated with the first ID to the UL packet; and transmitting the UL packet with second ID to the network. 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: A method and apparatus for supporting a hybrid mode positioning scheme in a wireless communication system is provided. While using a first positioning mode, a user equipment (UE) receives information on a triggering condition for the positioning mode switch from a network, i.e. an evolved serving mobile location center (E-SMLC). The UE determines that the triggering condition is satisfied, and switches the positioning mode from the first positioning mode to a second positioning mode.

Abstract: A method for transmitting, by a first relay user equipment (UE), signals by considering interferences in a further enhancement D2D (FeD2D) environment comprises the steps of: calculating, by the first relay UE, a distance to a virtual remote user equipment (UE) located on a straight line between the first relay UE and a second relay UE; determining an allowable interference intensity for the virtual remote UE, on the basis of a predetermined target signal to interference and noise ratio (SINR) value for the virtual remote UE and an intensity of a received signal from the second relay UE of the virtual remote UE; determining a transmission power on the basis of the allowable interference intensity and the calculated distance; and comparing the determined transmission power with a minimum transmission power that satisfies the target SINR, wherein the virtual remote UE may be located at a threshold of a target range of the second relay UE.

Abstract: The present invention provides a method and an apparatus performing device-to-device (D2D) communication in a wireless communication system. More particularly, D2D terminals supporting D2D communication are identified, discovery groups are formed for the D2D terminals using the same application, and discovery timing is established depending on the discovery group such that D2D terminals belonging to the same discovery group are shifted to an active state during the discovery timing in order to transceive signals by using time and frequency resources designated for D2D discovery with the discovery timing having a variable value depending on the discovery group.
