Abstract: Embodiments of the present disclosure provide an encoding method for a traffic indication map and a beacon frame, which relate to a communication field, enable a user to know whether there are data cached in an access point or enable a user terminal to know whether to access to a channel, and reduce the quantity of bytes occupied by the traffic indication map in the beacon frame. The encoding method for a traffic indication map provided by the embodiments comprises: controlling whether to display a sub-block bitmap display field in a sub-bitmap by marking at least one bit in a bitmap control field, a sub-block sub-bitmap in the sub-bitmap being used for enabling a user terminal to know whether there are data cached in an access point, or enabling the user terminal to know whether to access to a channel.

Abstract: The embodiments of the present invention provide a method and an apparatus for transmitting a data frame. The method comprises: acquiring at least one address of a destination address (DA) and a source address (SA), that are corresponding to data transmission direction information; determining, according to the data transmission direction information, an address field for carrying at least one address of the DA and the SA; and sending the data frame comprising the address field to a receiver. The method and apparatus for transmitting a data frame disclosed by the present invention can reduce overhead of an MAC frame header, improve transmission efficiency, and enable a station to acquire DA and/or SA of a data frame.

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.
