METHOD AND DEVICE FOR TRANSMITTING FRAME IN WIRELESS LAN

摘要

A method and a device for transmitting a frame in a wireless LAN are disclosed. A method for transmitting a data unit in a wireless LAN can comprise the steps of: transmitting, by an AP, an RTS frame for medium protection to a plurality of STAs through a plurality of channels; receiving, by the AP, a CTS frame in response to the RTS frame from each of the plurality of STAs through a first allocation channel, wherein the first allocation channel is at least one of the plurality of channels, which is determined on the basis of the RTS frame; and transmitting, by the AP, downlink data to each of the plurality of STAs through a second allocation channel on the basis of OFDMA in overlapped time resources, wherein the second allocation channel is at least one of the plurality of channels.

1. A method of transmitting a frame in a wireless local area network (WLAN), the method comprising:
transmitting, by an access point (AP), a Request to Send (RTS) frame for medium protection to a plurality of stations (STAs) through a plurality of channels; receiving, by the AP, a Clear to Send (CTS) frame in response to the RTS frame from each of the STAs through a first allocated channel, the first allocated channel being at least one channel among the plurality of channels determined based on the RTS frame; and transmitting, by the AP, downlink data to each of the plurality of STAs through a second allocated channel based on orthogonal frequency division multiplexing access (OFDMA) on an overlapping time resource, the second allocated channel being at least one channel among the plurality of channels.
