Method and apapratus for transmitting a frame in a wireless LAN system

摘要

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.

1. A method of transmitting, by an access point (AP), a frame in a wireless local area network (WLAN) system, the method comprising:
receiving single-tone request to send (sRTS) frames from a plurality of stations (STAs) respectively through one orthogonal frequency division multiplexing (OFDM) symbol and one subcarrier; selecting STAs that will perform uplink (UL) multi user (MU) multiple-input multiple-output (MIMO) transmission; and transmitting single-tone clear to send (sCTS) frames allocated to the same subcarrier to which sRTS frames received from the selected STAs have been allocated to the plurality of STAs.
