Abstract
Disclosed is a method and a device for transmitting and receiving a PPDU based on FDR in a wireless LAN system. More specifically, an AP generates FDR indication information on that the AP is capable of performing the FDR and transmits a DL PPDU including the FDR indication information to a first STA and a second STA. The AP receives a first UL PPDU from the first STA and a second UL PPDU form the second STA. A DL PPDU, a first UL PPDU, and a second UL PPDU are transmitted and received based on the FDR.

A method for transmitting and receiving a Physical layer Protocol Data Unit (PPDU) based on Full-Duplex Radio (FDR) in a wireless LAN system, the method comprising:
- generating, by an access point (AP), FDR indication information on that the AP is capable of performing the FDR;
- transmitting, by the AP, a downlink (DL) PPDU including the FDR indication information to a first station (STA) and a second STA;
- and
- receiving, by the AP, a first uplink (UL) PPDU from the first STA and a second UL PPDU from the second STA,
- wherein the DL PPDU includes a legacy signal field, a first signal field, a second signal field, and a DL data field;
- the second signal field includes allocation information on a first resource unit (RU) to which the DL data field is allocated;
- when the DL PPDU further includes a third signal field, the third signal field includes allocation information on a second RU to which the first UL PPDU and the second UL PPDU are allocated, information on an identifier of an STA to transmit the first UL PPDU and the second UL PPDU, and information on transmission time of the first UL PPDU and the second UL PPDU;
- the second RU is an RU excluding the first RU from a first band;
- the DL PPDU, the first UL PPDU, and the second UL PPDU are transmitted and received based on the FDR;
- the first UL PPDU is received from the first STA through half of the second RU;
- and
- the second UL PPDU is received from the second STA through the other half of the second RU.
An access point (AP) transmitting and receiving a Physical layer Protocol Data Unit (PPDU) based on Full-Duplex Radio (FDR) in a wireless LAN system, the AP comprising:
- a transceiver transmitting or receiving a radio signal;
- and
- a processor controlling the transceiver, wherein the processor is configured to
- generate FDR indication information on that the AP is capable of performing the FDR;
- transmit a downlink (DL) PPDU including the FDR indication information to a first station (STA) and a second STA;
- and
- receive a first uplink (UL) PPDU from the first STA and a second UL PPDU from the second STA, wherein
- the DL PPDU includes a legacy signal field, a first signal field, a second signal field, and a DL data field;
- the second signal field includes allocation information on a first resource unit (RU) to which the DL data field is allocated;
- when the DL PPDU further includes a third signal field, the third signal field includes allocation information on a second RU to which the first UL PPDU and the second UL PPDU are allocated, information on an identifier of an STA to transmit the first UL PPDU and the second UL PPDU, and information on transmission time of the first UL PPDU and the second UL PPDU;
- the second RU is an RU excluding the first RU from a first band;
- the DL PPDU, the first UL PPDU, and the second UL PPDU are transmitted and received based on the FDR;
- the first UL PPDU is received from the first STA through half of the second RU;
- and
- the second UL PPDU is received from the second STA through the other half of the second RU.
