Abstract
Proposed are a method and apparatus for transmitting a SU PPDU to a peer STA in a TXOP period allocated by a trigger frame in a wireless LAN system. Specifically, a first STA receives an MU-RTS frame from an AP. The first STA transmits a CTS frame to the AP. The first STA transmits a first SU PPDU to the AP or a second STA. The MU-RTS frame includes information about a TXOP period in which the first SU PPDU may be transmitted. The CTS frame includes type information. The AP is set to a doze state after the CTS frame is received.

A method in a wireless local area network (WLAN) system, the method comprising:
- receiving, by a first station (STA), a multi user-request to send (MU-RTS) frame from an access point (AP);
- transmitting, by the first STA, a clear to send (CTS) frame to the AP;
- and
- transmitting, by the first STA, a first single user (SU) physical layer protocol data unit (PPDU) to the AP or the second STA,
- wherein the MU-RTS frame includes information on a Transmission Opportunity (TXOP) period in which the first SU PPDU can be transmitted,
- wherein the CTS frame includes type information, and
- wherein the AP is set to a doze state after receiving the CTS frame.
A first station (STA) in a wireless local area network (WLAN) system, the first STA comprising:
- a memory;
- a transceiver;
- and
- a processor operatively coupled to the memory and the transceiver,
- wherein processor is configured to:
- receive a multi user-request to send (MU-RTS) frame from an access point (AP);
- transmit a clear to send (CTS) frame to the AP;
- and
- transmit a first single user (SU) physical layer protocol data unit (PPDU) to the AP or the second STA,
- wherein the MU-RTS frame includes information on a Transmission Opportunity (TXOP) period in which the first SU PPDU can be transmitted,
- wherein the CTS frame includes type information, and
- wherein the AP is set to a doze state after receiving the CTS frame.
