    • 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.
    • 提供了一种用于在支持多个上行链路和下行链路载波的无线通信系统中对用户设备执行对基站的随机接入的方法。 在该方法中,系统信息包括下行链路分量载波和PRACH TF时隙中的每一个的小区标识符信息以及所有下行链路分量载波共同的前导序列信息,所述系统信息通过与小区标识符信息对应的每个下行链路分量载波进行广播 ,被收到。 通过使用所接收的PRACH TF时隙和前导序列信息,通过链路到下行链路分量载波的一个上行链路分量载波来发送PRACH前导码。 通过每个下行链路分量载波接收RACH响应。 小区标识符信息用于发送用户设备希望在下行链路分量载波之间接入的下行链路分量载波的无线电资源控制(RRC)连接请求信号和小区标识符信息。
