Abstract: The invention relates to a method comprising classifying user equipment (UE) cells, to which carrier aggregation is applied, into a plurality of time advance groups. Uplink-time synchronization is managed using the time synchronization of a primary cell (Pcell) in the time synchronization group to which the primary cell belongs. For other time synchronization groups, the uplink time synchronization is managed using the time synchronization of a secondary cell (SCell) that is particularly set in the relevant time synchronization group. Thus, the plurality of time synchronizations can be effectively managed for the UE and a base station (BS).

Abstract: A method and apparatus for a user equipment (UE) to transmit data to a network is disclosed. The UE sets a poll bit in a PDCP (Packet Data Convergence Protocol) PDU (Protocol Data Unit) to a first value to request a status report including a second FMN (First Missing Number) from the network, if a predetermined number of PDCP SDUs (Service Data Units) are transmitted after a PDCP SDU corresponding to a first FMN.

Abstract: A method and apparatus for indicating quality of service (QoS) of device-to-device (D2D) data in a wireless communication system is provided. A first user equipment (UE) determines a value of a field in a header based on an identified QoS of the D2D data, and transmits to a second UE a layer 2 protocol data unit (PDU), which includes the header including the field having the determined value. Upon receiving the layer 2 PDU, the second UE identifies the QoS of the D2D data based on the value of the field in the header.

Abstract: A method and apparatus for transmitting information in a wireless communication system is provided. A first node receives an indication which indicates that a secondary cell (SCell) is added by a user equipment (UE), and information on the added SCell, and transmits an SCell addition request, including the information on the added SCell and an identity of the UE, to a second node. Alternatively, a method for transmitting information in a wireless communication system is provided. The first node receives an indication which indicates that an SCell is released by a UE, and information on the released SCell, and transmits an SCell release request, including the information on the released SCell and an identity of the UE, to a second node.
