METHOD AND APPARATUS OF TRANSMITTING DATA IN MULTIPLE CARRIER SYSTEM

摘要

PURPOSE: A method and a device for transmitting data in a multiple subcarrier system are provided to remove ambiguity using an uplink subcarrier for transmitting uplink data. CONSTITUTION: A base station transmits uplink resource assignment to a PDCCH through at least one downlink subcarrier among a plurality of downlink subcarriers(S710). A terminal maps the downlink subcarrier transmitting the PDCCH according to a subcarrier mapping rule to the upper link subcarrier(S720). The terminal transmits the uplink data to a PUSCH comprised through the uplink resource allocation through the mapped uplink subcarrier(S730). The multi subcarrier system defines the mapping rule between the downlink subcarriers and the uplink subcarriers for performing dynamic scheduling. The uplink data is transmitted using the uplink subcarrier corresponding to the downlink subcarrier according to the defined mapping rule.
