Wireless communication method for simultaneous data communication, and wireless communication terminal using same

A wireless communication terminal comprising:

• a transceiver;
• and
• a processor,
• wherein the terminal receives a wireless signal through the transceiver,
• wherein the processor is configured to:
• extract length information from the wireless signal, wherein the length information represents duration of the wireless signal,
• extract basic service set (BSS) identifier information of the wireless signal,
• determine whether the wireless signal is a wireless signal of an overlapping BSS based on the extracted BSS identifier information, and
• set a transmission opportunity (TXOP) of the terminal based on the extracted length information when the wireless signal is determined to be a wireless signal of an overlapping BSS.
