Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for allocating uplink resources in the wireless communication system, the method comprising: transmitting, by a first eNB to a second eNB, uplink (UL) resource allocation information for a user equipment (UE) connected with both the first eNB and the second eNB; receiving, by a first eNB from the UE, buffer size information; allocating one or more UL resources to the UE, by considering both of the buffer size information and the UL resource allocation information, wherein the UL resource allocation information indicates a ratio of the buffer size to be considered in each eNB.

Abstract: In the present invention, a user equipment (UE) receives semi-persistent scheduling (SPS) configuration information on N SPS resource configurations, where N is an integer larger than 1. The UE receives an SPS command to activate or deactivate each of multiple SPS resource configurations among the N SPS resource configurations. The UE performs downlink reception or uplink transmission in an SPS resource corresponding to an SPS resource configuration among activated SPS resource configurations. The SPS command includes information indicating each of the multiple SPS resource configurations and information indicating whether a corresponding SPS resource configuration is activated or deactivated.

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.
