Method for d2d signal transmission in wireless communication system, and terminal using same

Abstract

Provided is a method for device-to-device (D2D) signal transmission performed by a terminal in a wireless communication system, and a terminal device using the method. The method is characterized by: receiving measurement carrier (MEA_CARRIER) indication information which indicates a single downlink carrier to be used in downlink measurement and synchronization for D2D operation; and using, for the downlink measurement and synchronization for D2D operation, the single downlink carrier indicated by the measurement carrier (MEA_CARRIER) indication information.

         15 . A method for a relay user equipment (UE) to communicate with a remote UE in a wireless communication system, the method comprising:
 establishing a connection with the remote UE which is in radio resource control (RRC) idle state related to a base station;   receiving system information from the base station; and   transmitting the system information to the remote UE.   
     
     
         16 . The method of  claim 15 , wherein the system information is related to a sidelink communication between the relay UE and the remote UE. 
     
     
         17 . The method of  claim 15 , wherein the relay UE is in RRC connected state. 
     
     
         18 . The method of  claim 15 , wherein the remote UE is located out of a coverage of the base station. 
     
     
         19 . A relay user equipment (UE) comprising:
 a transceiver for transmitting and receiving a radio signal; and   a processor coupled to the transceiver, wherein the processor is configured to:   establish a connection with a remote UE which is in radio resource control (RRC) idle state related to a base station;   receive system information from the base station; and   transmit the system information to the remote UE.   
     
     
         20 . The relay UE of  claim 19 , wherein the system information is related to a sidelink communication between the relay UE and the remote UE. 
     
     
         21 . The relay UE of  claim 19 , wherein the relay UE is in RRC connected state. 
     
     
         22 . The relay UE of  claim 19 , wherein the remote UE is located out of a coverage of the base station. 
     
     
         23 . A processor for a wireless communication device in a wireless communication system, wherein the processor controls the wireless communication device configured to:
 establish a connection with a remote UE which is in radio resource control (RRC) idle state related to a base station;   receive system information from the base station; and   transmit the system information to the remote UE.   
     
     
         24 . The processor of  claim 23 , wherein the system information is related to a sidelink communication between the relay UE and the remote UE. 
     
     
         25 . The processor of  claim 23 , wherein the relay UE is in RRC connected state. 
     
     
         26 . The processor of  claim 23 , wherein the remote UE is located out of a coverage of the base station.
