A METHOD OF CHANNEL MANAGEMENT FOR MULTIPLE COMPONENT CARRIER IN MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE: A method for managing a channel for a multi carrier structure in a wireless communication system is provided to stop the receiving operation of a corresponding carrier by immediately initializing a down link retransmission buffer in a terminal in a deactivated state of a sub-carrier in a multi carrier environment. CONSTITUTION: A base station permits the initial transmission of data(510). The terminal performs the initial transmission of the data(520). The base station permits the retransmission of the data(530). The terminal performs the retransmission of the data(540). Data initial transmission permission in the base station, the data initial transmission of the terminal, the data retransmission permission of the base station, and the retransmission operation of the terminal are repetitively performed. The base station determines a wireless channel condition(550). The transmission interruption of a corresponding carrier is commanded(560). The base station stops the retransmission permission for the corresponding carrier(570). The terminal stops a retransmission procedure by receiving a transmission interruption command(580).
