Abstract: Embodiments of the present invention relate to communication technologies, in particular, to a method and an apparatus for protocol transmission in a wireless local area network. A method for transmitting multi-user data in a reverse direction protocol according to an embodiment of the present invention includes: within a transmission opportunity (TXOP) of a first station, if the TXOP is not over after the first station finishes sending data to an access point (AP), obtaining, by the AP, the TXOP, where the obtaining, by the AP, the TXOP is implemented through granting a remaining part of the TXOP to the access point AP by the first station as a reverse direction protocol initiator; and within the TXOP, sending, by the AP, second data to at least two stations, where the at least two stations include the first station.

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.

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.
