Wireless communication method for simultaneous data transmission and reception and wireless communication apparatus using same
First Claim
1. A wireless communication method of a terminal, the method comprising:
- receiving, from an AP, a trigger frame indicating transmission(s) of at least one terminal in a same basic service set (BSS);
obtaining duration information indicated by the trigger frame;
performing a data transmission in response to the reception of the trigger frame; and
receiving acknowledgement frame corresponding to the data transmission based on the duration information;
wherein, in response to the trigger frame, multiple data transmissions are simultaneously performed by a plurality of terminals in the same BSS when the plurality of terminals are indicated by the trigger frame, andwherein the receiving the acknowledgement frame comprises, when a duration of the data transmission is shorter than a duration corresponding to the duration information indicated by the trigger frame, receiving the acknowledgement frame at a time determined based on the duration information indicated by the trigger frame.

Abstract
The present invention relates to a wireless communication method for simultaneous transmit and receive of data and a wireless communication terminal using the same, and more particularly, to a wireless communication method and an apparatus thereof which can efficiently perform simultaneous data transmission and reception even in an overlapped BSS environment.
To this end, provided are a wireless communication method of a terminal, including: performing a backoff procedure for transmitting data; transmitting a first RTS frame when a backoff counter of the backoff procedure is expired; setting a transmission timer for waiting for transmitting the data when a second RTS frame is received in response to the transmitted first RTS frame; and waiting for transmitting the data based on the set transmission timer and a wireless communication terminal using the same.
