    • The present invention relates to a wireless access system, and more particularly, to an initial access system under a multi-carrier combination condition. A method for performing an initial access in a base station which supports the multi-band of a terminal according to one embodiment of the present invention comprises the steps of: searching one or more downlink component carriers of the base station; receiving system information including a broadcast channel of a first downlink component carrier from among the searched one or more downlink component carriers and information for indicating one or more uplink component carriers connected to the first downlink component carrier; transmitting a first message to the base station through a first uplink component carrier from among one or more uplink component carriers indicated by the received system information; and receiving a second message including uplink authorization information from the base station through the first downlink component carrier.
    • 多载波组合条件下的初始接入系统技术领域本发明涉及无线接入系统,并且更具体地涉及多载波组合条件下的初始接入系统 根据本发明的一个实施例的用于在支持终端的多频带的基站中执行初始接入的方法包括步骤:搜索基站的一个或多个下行链路分量载波; 接收包括搜索到的一个或多个下行链路分量载波中的第一下行链路分量载波的广播信道的系统信息以及用于指示连接到第一下行链路分量载波的一个或多个上行链路分量载波的信息; 通过第一上行链路分量载波从由所接收的系统信息指示的一个或多个上行链路分量载波中向基站发送第一消息; 以及通过第一下行链路分量载波从基站接收包括上行链路授权信息的第二消息。
