Abstract
The present specification relates to a method for transmitting a signal by a station in a wireless LAN (WLAN) system. More specifically, the present specification proposes a frequency division multiple access (FDMA) frame structure for transmitting, by a station, a signal to a plurality of stations by using an FDMA method, and presents a method for transmitting a signal on the basis of the FDMA frame structure and a device therefor.
Claims16
A method for transmitting a signal by an access point (AP) to a first station (STA) and a second STA in accordance with a frequency division multiple access (FDMA) method in a wireless LAN (WLAN) system, the method comprising:
- determining an FDMA frame structure based on one or more first channels allocated to the first STA and one or more second channels allocated to the second STA;
- and
- transmitting the signal to the first STA and the second STA based on the determined FDMA frame structure,
- wherein the determined FDMA frame structure includes a first direction current (DC) tone located at a center of a first frequency band corresponding to the one or more first channels allocated to the first STA and a second DC tone located at a center of a second frequency band corresponding to the one or more second channels allocated to the second STA.
An access point (AP) device for transmitting a signal in a wireless LAN (WLAN) system, the AP device comprising:
- a transceiver having one or more radio frequency (RF) chains, configured to transmit and receive a signal to and from a first station (STA) and a second STA in accordance with a frequency division multiple access (FDMA) method;
- and
- a processor connected with the transceiver, processing signal transmission and reception with the first STA and the second STA,
- wherein the processor is configured to:
- determine an FDMA frame structure based on one or more first channels allocated to the first STA and one or more second channels allocated to the second STA;
- and
- transmit the signal to the first STA and the second STA based on the determined FDMA frame structure, and
- wherein the determined FDMA frame structure includes a first direction current (DC) tone located at a center of a first frequency band corresponding to the one or more first channels allocated to the first STA and a second DC tone located at a center of a second frequency band corresponding to the one or more second channels allocated to the second STA.
