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 for a user equipment (UE) to receive a downlink signal. The UE receives a first downlink assignment including a first new data indicator (NDI) from a base station. The UE compares the first NDI to a second NDI and, based on a result of the comparison, determines whether the first NDI has been toggled. The UE receives the downlink signal and processes the received downlink signal based on whether the first NDI has been determined to be toggled. Furthermore, the second NDI is included in a second downlink assignment that was previously received from the base station and was not identified by a temporary cell identifier.
