Abstract
A full-duplex communication method in a high efficiency wireless local area network (WLAN), the full-duplex communication method being performed by an access point (AP) in a WLAN network, includes transmitting a reference frame to at least one station (STA); receiving an uplink frame from the at least one STA in a time period determined on the basis of the reference frame; and transmitting a downlink frame to the at least one STA in a specific time duration of the time period, wherein the uplink frame and the downlink frame are transmitted through the same channel.

A full-duplex communication method in a high efficiency wireless local area network (WLAN), the full-duplex communication method being performed by an access point (AP) in a WLAN network, the method comprising:
- transmitting a reference frame to at least one station (STA);
- receiving an uplink frame from the at least one STA in a time period determined on a basis of the transmitted reference frame;
- and
- transmitting a downlink frame to the at least one STA in a specific time duration of the time period,
- wherein the uplink frame and the downlink frame aligned at frame boundaries in the time period are transmitted simultaneously through a same channel,
- wherein a legacy part of the downlink frame is a null field in which no signal is transmitted or another signal type is transmitted, and
- wherein a non-legacy part of the downlink frame and a non-legacy part of the uplink frame are aligned in a specific time duration of the time period.
A full-duplex communication method in a high efficiency wireless local area network (WLAN), the full-duplex communication method being performed by a specific station (STA) in a WLAN network, the method comprising:
- receiving a reference frame from an access point (AP);
- transmitting an uplink frame to the AP in a time period determined on a basis of the reference frame;
- and
- receiving a downlink frame from the AP in a specific time duration of the time period determined by the reference frame,
- wherein the reference frame is transmitted to a plurality of STAs including the specific STA,
- wherein the time period is a period in which at least one of the plurality of STAs is solicited to transmit an uplink frame to the AP,
- wherein the uplink frame and the downlink frame aligned at frame boundaries in the time period are transmitted simultaneously through a same channel,
- wherein a legacy part of the downlink frame is a null field in which, and
- wherein a non-legacy part of the downlink frame and a non-legacy part of the uplink frame are aligned in a specific time duration of the time period.
A station apparatus for performing full-duplex communication in a high efficiency wireless local area network (WLAN), the station apparatus comprising:
- a communication device configured to receive a reference frame from an access point (AP) in a WLAN, transmit an uplink frame to the AP in a time period, and receive a downlink frame from the AP in a specific time duration of the time period;
- and
- a processor configured to determine the time period or the specific time duration based on the reference frame and process the downlink frame transmitted in the specific time duration,
- wherein the reference frame is transmitted to a plurality of stations including the station apparatus,
- wherein the time period is a period in which at least one of the plurality of stations transmits an uplink frame to the AP,
- wherein the uplink frame and the downlink frame aligned at frame boundaries in the time period are transmitted simultaneously through a same channel,
- wherein a legacy part of the downlink frame is a null field in which no signal is transmitted or another signal type is transmitted, and
- wherein a non-legacy part of the downlink frame and a non-legacy part of the uplink frame are aligned in a specific time duration of the time period.
