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: This application provides a voiceprint recognition method and device. The method includes: calculating, by an electronic device a first confidence value that an entered voice belongs to a first registered user, and calculating a second confidence value that the entered voice belongs to a second registered user. The method further includes: calculating, by another electronic device, a third confidence value that the entered voice belongs to the first registered user, and calculating a fourth confidence value that the entered voice belongs to the second registered user. A server determines, based on the first confidence value and the third confidence value, a fifth confidence value that a user is the first registered user, and determines, based on the second confidence value and the fourth confidence value, a sixth confidence value that the user is the second registered user.
