Abstract:
The present invention relates to a method and apparatus for transmitting a frame in a wireless LAN system. An access point (AP) receives a single orthogonal frequency division multiplexing (OFDM) symbol from each of a plurality of stations (STA) and a single-tone request to send (sRTS) frame through a single subcarrier, selects STAs for performing uplink (UL) multiuser (MU)-multiple input multiple output (MIMO) transmission, and transmits to the plurality of STAs a single-tone clear to send (sCTS) frame allocated to the same subcarrier as a subcarrier to which the sRTS frames received from the selected STAs are allocated.
