DYNAMIC INTER-FRAME SPACE PROCESSING IN HIGH EFFICIENCY WIRELESS LAN

摘要

The present invention relates to a transmission and receiving method and apparatus using a dynamically determined Inter-Frame Space (IFS) in a Wireless Local Area Network (WLAN). According to one aspect of the present invention, a method for processing a received frame by a Station (STA) in a WLAN may include receiving a first frame including downlink data for a plurality of STAs, if the received first frame has no error, transmitting a second frame including an ACKnowledgement (ACK) of the STA simultaneously with ACKs of one or more other STAs, and if the received first frame has an error, performing carrier sensing using a variably determined IFS.
