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: 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.

Abstract: Embodiments of the present invention provide a method for data sending in a multi-user multiple-input multiple-output (MU-MIMO) system. The method includes: sending data to the primary user and the secondary user on the bandwidth on which the clear to send (CTS) sent by the primary user is received and a bandwidth on which the CTS sent by the secondary user is received. The bandwidth on which the request to send (RTS) is sent to the secondary user in this solution may be dynamically adjusted according to an available bandwidth of the primary user, so that sending of unnecessary RTSs on some secondary channels is avoided and send power of an AP and send power of a user are saved.
