    Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for canceling a scheduling request triggered by a sidelink buffer status report in a D2D communication system, the method comprising: triggering one or more sidelink Buffer Status Reports (BSRs) for sidelink data available for transmission; triggering one or more Scheduling Requests (SRs); configuring one or more sidelink grants in one or more subframes within a certain period; checking, in a first subframe, whether remaining sidelink grants can accommodate all pending data available for transmission; and canceling the all of the one or more triggered SRs if the all of the one or more triggered SRs are triggered by the one or more sidelink BSRs and the remaining sidelink grants can accommodate all of the pending data available for transmission, wherein the remaining sidelink grants are sidelink grants configured in one or more subframes starting from the first subframe to end of the certain 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 and reporting a buffer status in the wireless communication system, the method comprising: configuring a plurality of logical channel sets comprising a first logical channel set transmitting data to the first BS and a second logical channel set transmitting data to the second BS, wherein the first and the second logical channel sets respectively comprise one or more logical channels; receiving data for a first logical channel belonging to the first logical channel set; and triggering a buffer status reporting to the first BS, if the first logical channel has highest priority among logical channels for which data are available for transmission in the first logical channel set.

    Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for calculating and reporting a buffer status in the wireless communication system, the method comprising: receiving a Packet Data Convergence Protocol (PDCP) data transmission ratio and an offset value; calculating a first buffer status for the first BS and a second buffer status for the second BS based on the PDCP data transmission ratio; starting a timer for the first BS when the calculated first buffer status is reported to the first BS; checking whether an uplink (UL) grant is received from the first BS when the timer for the first BS expires; and updating the PDCP data transmission ratio using the offset value if the UL grant is not received from the first BS; and re-calculating the first buffer status for the first BS and the second buffer status for the second BS based on the updated PDCP data transmission ratio.

    Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for de-configuring a cell from PUCCH resource in a carrier aggregation system, the method comprising: configuring a Secondary Cell (SCell) with Physical Uplink Control Channel (PUCCH) resource; receiving a Radio Resource Control (RRC) signaling indicating that the PUCCH resource is de-configured from the SCell with the PUCCH resource; de-configuring the PUCCH resource from the SCell according to the RRC signaling; re-activating the SCell; and starting a SCell deactivation timer associated with the SCell.
