    Abstract: A method for transmitting sidelink data by a User Equipment (UE) in a wireless communication system includes determining whether resource pool information for selecting a sidelink grant is configured by a base station; determining whether more sidelink data is available in a Sidelink Traffic Channel (STCH) than can be transmitted in a current Sidelink Control (SC) period; selecting resources for the sidelink grant from the resource pool information based on the resource pool information for selecting the sidelink grant being configured by the base station, and more sidelink data being available in the STCH than can be transmitted in the current SC period; selecting resources for the sidelink data based on the resources for the sidelink grant; and transmitting the sidelink data to another UE through the resources for the sidelink data. Further, the sidelink grant is for a next SC period after the current SC period.

    Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for triggering a buffer status reporting in dual connectivity, the method comprising: configuring a threshold value for a PDCPentity associated with a first MAC entity for a first eNB and a second MAC entity for a second eNB for a radio bearer; checking, by the PDCP entity, whether an amount of uplink data available for transmission in the PDCP entity is less than the threshold value; and indicating, by the PDCP entity, that the amount of uplink data available for transmission in the PDCP entity is ‘0’ to the second MAC entity, if the amount of uplink data available for transmission in the PDCP entity is less than the threshold value.
