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: Provided are a method and an apparatus for obtaining a downlink synchronization in a wireless communication system. A proposed wireless communication system has an environment in which a resource position of a downlink synchronization signal is changed as multi-numerology is applied thereto. Specifically, a terminal transmits a preamble for requesting a synchronization signal transmission resource to a base station. The terminal receives a response signal to the preamble from the base station. Here, the terminal does not have linkage to the base station, and is downlink synchronized with the base station. The response signal includes position information of a synchronization signal transmission resource of a neighboring base station.

Abstract: A method and device for receiving a signal in a wireless communication system to which a multiplex transmission technique is applied are provided. The wireless communication system proposed herein suggests a method for increasing the receipt reliability of a terminal with respect to a multiplex transmission activation indicator indicating the start of multiplex transmission. Particularly, a terminal checks the receipt of a multiplex transmission activation indicator transmitted, from a first base station, for every predetermined subframe. If the terminal succeeds in receiving the multiplex transmission activation indicator, an ACK signal associated with the multiplex transmission activation indicator is transmitted to the first base station. Here, the multiplex transmission activation indicator indicates that the first base station and a second base station are capable of transmitting the same data for a predetermined time together.

Abstract: Provided are a method and device for transmitting a scheduling request in a wireless communication system. In detail, a terminal receives, from a base station, resource allocation information for indicating a semi-persistent scheduling request and a scheduling request resource. The terminal receives, from the baste station, a first indicator for indicating whether the semi-persistent scheduling resource is activated and a second indicator for indicating whether the scheduling request resource is activated. The terminal determines whether the scheduling request can be transmitted on the basis of the first indicator and the second indicator. The terminal transmits the scheduling request to the base station via the scheduling request resource indicated by the resource allocation information.

Abstract: Provided are a method and a device for transmitting a scheduling request in a wireless communication system. Particularly, user equipment receives information on first and second scheduling request resources which is broadcasted from a base station. The user equipment receives information on the first and second scheduling request resources which is transferred specifically to the user equipment from the base station. On the basis of the information, the user equipment selects the first scheduling request resource or the second scheduling request resource. The user equipment transmits a scheduling request via the selected resource.
