    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 segmenting and reordering a RLC status PDUs in the wireless communication system, the method comprising: generating an RLC status PDU (Radio Link Control status Protocol Data Unit); segmenting the generated RLC status PDU if a size of transmitting resource is smaller than a size of the generated RLC status PDU; generating a plurality of Segment RLC status PDUs, wherein each Segment RLC status PDU has a segment of the generated RLC status PDU and a RLC header including segmentation information; and transmitting the plurality of Segment RLC status PDUs.
