    Abstract: Disclosed are channel management methods in a multicarrier structure in a mobile communication system. Uplink (UL) and downlink (DL) channel management methods in a carrier aggregation environment are used as the channel management methods. In DL, a base station determines a component carrier (CC) of an unstable radio channel state, stops data retransmission by the CC, and notifies a terminal of retransmission stop. In UL, the base station determines a CC of an unstable radio channel state and instructs the terminal to stop data retransmission by the CC, and the terminal stops the data retransmission and initializes a retransmission buffer. Using the channel management methods in the mobile communication system employing the multicarrier structure, an increase in the number of unnecessary retransmissions is prevented, so that unnecessary retransmission and power consumption of the terminal can be reduced and the waste of radio resources and the degradation of base station performance due to unnecessary retransmission can be prevented.

    Abstract translation: 公开了移动通信系统中的多载波结构中的信道管理方法。 使用载波聚合环境中的上行链路（UL）和下行链路（DL）信道管理方法作为信道管理方法。 在DL中，基站确定不稳定的无线信道状态的分量载波（CC），停止CC的数据重传，并向终端通知重传停止。 在UL中，基站确定不稳定无线信道状态的CC，并指示终端停止CC的数据重发，终端停止数据重发，并初始化重发缓冲器。 使用采用多载波结构的移动通信系统中的信道管理方法，防止了不必要的重发次数的增加，从而可以减少终端的不必要的重传和功耗，并且无线资源的浪费和基站的劣化 可以防止由于不必要的重发引起的站性能。

    Abstract: Provided are a method for performing handover in a cellular mobile communication system that supports a carrier aggregation, and a user equipment and a node base (NodeB) using the method. A connection between the user equipment and the NodeB may be maintained and information may be exchanged using a plurality of serving carriers. Before performing the handover, the user equipment may perform measurement with respect to a neighboring NodeB supporting the carrier aggregation, and may provide parameter information to the NodeB in order to support a carrier aggregation function required for the handover. In a handover seamless environment, the continuity of a service may be provided and the performance of the service may be enhanced.
