Abstract: A method includes: sending an indication frame to an access point AP, where the indication frame includes first indication information and second indication information, the first indication information is used to indicate that a type of the indication frame is a PS-POLL frame, and the second indication information is used to indicate duration of the indication frame; and sending a data frame to the AP within the duration indicated by the second indication information. An STA sends PS-POLL to an AP by using an indication frame and reserves channel duration, so that the STA does not need to contend for a channel again when the STA sends an uplink data frame to the AP after receiving a downlink data frame sent by the AP, which allows the STA to receive downlink data and send uplink data within one TXOPA.
Abstract translation: 一种方法包括：向接入点AP发送指示帧，其中指示帧包括第一指示信息和第二指示信息，第一指示信息用于指示指示帧的类型是PS-POLL帧，以及 第二指示信息用于指示指示帧的持续时间; 以及在由所述第二指示信息指示的持续时间内向所述AP发送数据帧。 STA通过使用指示帧向AP发送PS-POLL并且保留信道持续时间，使得STA在接收到发送的下行链路数据帧之后向AP发送上行链路数据帧时不需要再次争用信道 由AP允许STA接收下行链路数据并在一个TXOPA内发送上行链路数据。

Abstract: A power save method and a station device. The method includes: confirming, by a STA, according to a frame type identifier in a received frame, that the frame is an NDPA frame, and obtaining a STA AID in a STA information field in the NDPA frame; comparing, by the STA, its STA AID with the obtained STA AID, and determining whether its STA AID is the same as the obtained STA AID; and when the STA determines that its STA AID is different from the obtained STA AID, allowing the STA to enter a doze state. The method reduces the power consumption during the TXOP period and saves resources.
