Method of channel management for multiple component carrier in mobile communication system

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