Abstract: A wireless communication terminal is disclosed. The wireless communication terminal includes a transceiver configured to transmit/receive a wireless signal; and a processor configured to control an operation of the wireless communication terminal. The transceiver transmits a training signal to a base wireless communication terminal based on a sub-frequency band allocated from the base wireless communication terminal, and transmits data to the base wireless communication terminal through the sub-frequency band allocated from the base wireless communication terminal. The training signal is used, by the base wireless communication terminal, for receiving the data from the wireless communication terminal.
