Abstract
A method and a device for transmitting a multiuser uplink in the wireless LAN are disclosed. A method for receiving each uplink frame from a plurality of STAs in the wireless LAN can comprise the steps of: transmitting, by an AP, a downlink PPDU to the plurality of STAs on an overlapping time resource; and receiving, by the AP, each uplink frame from each of the plurality of STAs on an overlapping time resource through each uplink transmission resource with respect to each of the plurality of STAs, as the response to the downlink PPDU.

9. A method for a uplink (UL) multi-user (MU) transmission in a wireless local area network, the method comprising:
-
receiving, by a receiving station, from an access point (AP), a UL transmission indication frame for requesting a plurality of stations simultaneous UL MU transmissions, the UL transmission indication frame including identification information and resource allocation information, the identification information including a plurality of identifiers identifying the plurality of stations, the resource allocation information including frequency resources allocated to the plurality of stations; and when the receiving station confirms that the receiving station is one of the plurality of stations indicated by the identification information, transmitting, by the receiving station, to the AP, a UL physical layer protocol data unit (PPDU) by using a frequency resource allocated to the receiving station, wherein an interframe space between the UL transmission indication frame and the UL PPDU is a short inter frame space (SIFS). - View Dependent Claims (10, 11, 12, 13, 14)

15. A device for a uplink (UL) multi-user (MU) transmission in a wireless local area network, the device comprising:
-
a radio frequency (RF) unit configured to transmit and receive a radio signal; and a processor operatively coupled to the RF unit and configured to; control the RF unit to receive, from an access point (AP), a UL transmission indication frame for requesting a plurality of stations simultaneous UL MU transmissions, the UL transmission indication frame including identification information and resource allocation information, the identification information including a plurality of identifiers identifying the plurality of stations, the resource allocation information including frequency resources allocated to the plurality of stations; and control the RF unit to transmit, to the AP, a UL physical layer protocol data unit (PPDU) by using a frequency resource allocated to the receiving station when the device confirms that the device is one of the plurality of stations indicated by the identification information, wherein an interframe space between the UL transmission indication frame and the UL PPDU is a short inter frame space (SIFS) - View Dependent Claims (16, 17, 18, 19, 20)
