Abstract: Provided are a method in which a source base station (BS) transmits a Quality of Service (QoS) flow-to-data radio bearer (DRB) mapping rule to a target BS in a wireless communication system, and a device supporting the same. The method may include: receiving, from a user equipment (UE), a measurement result of a target cell; determining the handover of the UE to the target BS on the basis of the measurement result; and transmitting, to the target BS, a handover request message including a QoS flow-to-DRB mapping rule of the source BS.

Abstract: A method and a device for performing a random access procedure in a carrier aggregation with at least one SCell operating in an unlicensed spectrum are disclosed. The method includes: configuring a timer; starting the timer when the UE initiates a Random Access Preamble (RAP) transmission procedure on a first cell; and stopping the RAP transmission procedure on the first cell if a Random Access Response (RAR) for the RAP transmission procedure on the first cell is not received until the timer expires.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for cancelling BSR or SR in dual connectivity, the method comprising: receiving an UL data from an upper layer, triggering a BSR (or SR) for a first eNB due to the UL data, transmitting, to a second eNB, at least a part of the UL data using an UL grant received from the second eNB, and cancelling the triggered BSR (or pending SR) when an amount of data available for transmission to be transmitted to the first eNB changes to zero due to the transmission of the at least a part of the UL data, even if an UL grant in response to the triggered BSR (or pending SR) is not received from the first eNB.

Abstract: A method is provided for operating by a user equipment (UE) connected with a master base station (BS) and a secondary BS in a wireless communication system. The UE configures a first cell supporting a contention based random access and a second cell other than the first cell. The first cell and the second cell are associated with the secondary BS. The UE determines whether a radio link problem is occurred on the first cell or the second cell. The UE indicates the radio link problem to an upper layer only if the radio link problem occurs on the first cell.
