摘要：The present invention relates to a wireless communication system. More

specially, the present invention relates to a method of maintaining uplink synchronizationat a user equipment in a wireless communication system supporting carrier aggregation;configuring plural uplink component carriers, wherein each of the plural uplink

component carriers has a respective uplink synchronization timing; receiving a downlinkcontrol information (DCI) through a physical downlink control channel of a specificdownlink component carrier, wherein the DCI indicates an initiation of random accessprocedure and includes a carrier indicator field indicating one of the plurality of uplinkcomponent carriers; and transmitting a random access preamble through a uplinkcomponent carrier indicated by the carrier indicator field among the plural uplinkcomponent carriers.
