The present invention relates to a wireless communication method for simultaneous data communication and a wireless communication terminal using the same, and more particularly, to a wireless communication method for suppressing interference between terminals and ensuring fairness when performing data simultaneous communication for spatial reuse of communication system and wireless communication terminal using the same.For this, provided are a wireless communication method and a wireless communication terminal using the same. The method includes: receiving a wireless signal of a specific channel; extracting basic service set (BSS) identifier information of the received wireless signal; extracting length information from the wireless signal wherein the length information represents information relating to a transmission completion time point of the wireless signal; and adjusting a data transmission period of the terminal based on the extracted length information, when the BSS identifier information of the wireless signal is different from BSS identifier information of the terminal.
