Abstract: PURPOSE: A method for allocating resources and controlling power is provided to measure an interference amount due to an adjacent cell in a portable internet system, thereby efficiently controlling power of the terminal without exchanging information between base stations.

Abstract: PURPOSE: An effective hybrid-ARQ and ARQ scheme in a broadband wireless access system are provided to minimize an overhead of a feedback by interlinking HARQ and ARQ. CONSTITUTION: In a effective hybrid-ARQ and ARQ scheme in a broadband wireless access system, initial data is transmitted. A retransmission procedure is performed through a synchronous HARQ method, and a base station uses the asynchronous HARQ method by getting a scheduling gain. In the synchronous HARQ method, the conversation of the asynchronous HARQ method is informed to a terminal. An asynchronous mode indication field is inserted within a MAP message to inform a mode conversion to the terminal. The terminal recognizes the mode conversion, and the terminal inspects an assigned state of a retransmitting packet at each frame.
