Abstract: In the present invention, a user equipment (UE) receives resource configuration information including information on a first radio resource not dedicated to the UE. The UE performs transmission of uplink data using the first radio resource. The UE transmits a request for radio resource dedicated to the UE for retransmission of the uplink data if the transmission of the uplink data using the first radio resource is not successful for a certain number of transmissions of the uplink data or for a certain period of time.

Abstract: A transmitting device generates a medium access control (MAC) protocol data unit (PDU), and transmits the MAC PDU. The transmitting device generates the MAC PDU such that the MAC PDU includes at least a MAC service data unit (SDU) and a first MAC subheader of the MAC SDU which is attached immediately after the end of the MAC SDU, or a MAC control element (CE) and a second MAC subheader of the MAC CE which is attached immediately after the end of the MAC CE.

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: Method and apparatus for a user equipment (UE) supporting dual connectivity (DC) with a master node and a secondary node are disclosed. According to these, the UE receives first configuration information from the master node and second configuration information from the secondary node. The UE applies the first configuration information first. And, the UE transmits a new configuration request message to the secondary node, if the UE cannot apply the second configuration information after applying the first configuration information.
