    Abstract: A method for a User Equipment, UE, operating in a wireless communication system, includes triggering power headroom reports (PHRs), in a first Medium Access Control (MAC), entity and a second MAC entity when a first type event occurs in the second MAC entity, wherein the UE is configured with the first MAC entity corresponding to a first base station and the second MAC entity corresponding to a second base station for a radio bearer; triggering a PHR in the second MAC entity only, when a second type event occurs in the second MAC entity, wherein the first type event includes: there are uplink resources allocated for transmission on any cell of the second MAC entity and a required power backoff for the any cell of the second MAC entity has changed more than a threshold, or wherein the first type event includes: there is uplink transmission on any cell of the second MAC entity and a required power backoff for the any cell of the second MAC entity has changed more than a threshold.

    Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for handling for an uplink split operation in wireless communication system, the method comprising: generating and/or receiving second data available for transmission in a PDCP entity, and determining a RLC entity to be used for submitting the second data based on first data volume, if second data volume is larger than a first threshold and less than a second threshold; indicating the second data volume to a first MAC entity associated with a primary RLC entity, if the first data volume is less than the first threshold; and indicating the second data volume to both the first MAC entity associated with the primary RLC entity and a second MAC entity associated with a secondary RLC entity, if the first data volume is larger than the second threshold.

    Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting data in a wireless communication system. According to an aspect of the present invention, the method comprising: receiving, from an enhanced Node B (eNB), a grant with an indication that indicates at least one radio bearer (RB) of which data should be transmitted using the received grant, wherein each of RBs configured to the UE is associated with a respective logical channel priority; generating a medium access control protocol data unit (MAC PDU) including data of the indicated at least one RB; and transmitting the MAC PDU using the grant.

    Abstract: A method for a user equipment (UE) operating in a wireless communication system including a first base station (BS) and a second BS, includes configuring a first medium access control (MAC) entity to map a first logical channel set transmitting first data to the first BS and a second MAC entity to map a second logical channel set transmitting second data to the second BS, wherein the first logical channel set includes one or more logical channels and the second logical channel set includes one or more logical channels, if the first data belongs to a logical channel having a higher priority than priorities of logical channels for which data is already available for transmission in the first logical channel set, triggering, by the first MAC entity, a first buffer status report to the first BS regardless of priorities of logical channels of the second logical channel set.
