Abstract: A method and apparatus for configuring a cell in a wireless communication system is provided. A user equipment (UE) receives a radio resource control (RRC) message which includes a configuration for a secondary cell (SCell) and an indication of an initial state of the SCell. The initial state of the SCell is set to either one of an activated state and deactivated state. The UE configures the SCell based on the configuration and the initial state of the SCell.

Abstract: An eNodeB (eNB) receives a first paging message including a first user equipment (UE) identity (ID) from a mobility management entity (MME). The eNB checks whether a UE context mapped to the first UE ID is present or not. If it is checked that the UE context mapped to the first UE ID is present, the eNB transmits a second paging message including a second UE ID, which replaces the first UE ID, to a UE.

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).
