<p>A method for transmitting feedback data, a method for creating feedback data, and a data scheduling method are provided to reduce the overheads based on the transmission of feedback information by expressing various kinds of feedback information using feedback data having a certain size, without special identifiers. A base station transmits data, such as a preamble and a pilot signal, to a mobile terminal(S110). The mobile terminal determines feedback information from the transmitted data, creates feedback data, and transmits the created feedback data to the base station(S120,S130). The base station extracts feedback information from the feedback data received from the mobile terminal(S140). Then the base station selects a code rate, a modulation scheme, and a MIMO(Multiple Input Multiple Output) scheme through the extracted feedback information, schedules downlink data, and transmits the scheduled data to the mobile terminal(S150,S160).</p> |
