METHOD AND APPARATUS FOR PERFORMING UPLINK HARQ IN WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: An apparatus and a method for performing a hybrid automatic repeat request(HARQ) in a wireless communication system are provided to improve the adaptability of the HARQ using a multiple antenna. CONSTITUTION: A terminal receives HARQ setting information from a base station(S710). The base station transmits uplink-resource-allocation to the terminal through a physical downlink control channel(S720). The terminal transmits an initial transmission block through a physical uplink shared channel which is composed of the uplink-resource-allocation(S730). The base station transmits a receipt notification through a physical HARQ by verifying the errors of the initial transmission block(S740). A terminal regulates the transmission characteristic of a re-transmitting block based on the HARQ setting information(S750).
