摘要：
A method for a user equipment to perform random access to a base station in a wireless communication system that supports multiple uplink and downlink carriers is provided. In the method, system information including cell identifier information of each of the downlink component carriers and PRACH TF slot and preamble sequence information which is common to all downlink component carriers, the system information being broadcast through each downlink component carrier corresponding to the cell identifier information, is received. A PRACH preamble is transmitted through one uplink component carrier linked to the downlink component carriers using the received PRACH TF slot and preamble sequence information. An RACH response is received through each of the downlink component carriers. The cell identifier information is used to transmit a Radio Resource Control (RRC) connection request signal and cell identifier information of a downlink component carrier, which the user equipment desires to access among the downlink component carriers.
