Abstract: The present invention involves defining the operation of a terminal for determining which time alignment timer is to be applied to a certain condition when specific time alignment timers operate for each carrier-wave group in the event a wireless communication system uses a carrier aggregation technique. According to the present invention, a terminal may perform communication without malfunctions using a time alignment timer suitable for a certain condition. In detail, a method for a terminal to operate a time alignment timer according to the present invention comprises the steps of: receiving, from a base station, a message including a timing advance command and an index on a timing advance group (TAG); and operating the time alignment timer for the TAG, wherein the index has a value of 00 when the TAG includes a first cell. In the meantime, a method for a terminal to operate a time alignment timer according to the present invention comprises the steps of: operating a first time alignment timer for a first timing advance group (TAG) including a first cell; operating a second time alignment timer upon receipt of a timing advance command for a second TAG that does not include the first cell; and, if the first time alignment timer has expired, deeming the second time alignment timer to also be expired. In addition, a method for a base station to control a time alignment timer according to the present invention comprises the steps of: determining whether or not an uplink timing of a terminal needs correction; and transmitting a message including a timing advance command and an index on a timing advance group (TAG), wherein the index has a value of 00 when the TAG includes a first cell.
