Abstract
A method for reducing power consumption of a terminal that communicates with a base station in a mobile communication system using a multi-carrier structure composed of a primary component carrier and at least one secondary component carrier comprises: receiving a discontinuous reception (DRX) parameter group for multi carriers from the base station; and setting the multi carriers to the same parameter value, by using the received parameter group. The method for reducing power consumption of the terminal further comprises: performing a downlink control channel receive operation on each carrier according to a DRX cycle. As the base station in the mobile communication system using the multi-carrier structure simplifies the DRX process for reducing power consumption of a terminal by reducing signaling load for the multi-carrier control of the terminal, it becomes possible to reduce power consumption of the terminal.
