Abstract: Embodiments of this application provide a service protection method, including: A first node determines that a fault occurs on a first working path; the first node generates a bandwidth activation message based on the fault, where the bandwidth activation message indicates a third node to adjust a bandwidth of a service from a protection bandwidth to a target bandwidth, the protection bandwidth represents a pre-occupied bandwidth of a first protection path before transmission of the service, and the target bandwidth represents an actual occupied bandwidth for transmission of the service; and the first node sends the bandwidth activation message on the first protection path.

Abstract: Embodiments of the present invention provide a link adaptation feedback method and a transmitting device. The method includes: receiving, by a transmitting device, a link adaptation feedback frame sent by a receiving device, where the link adaptation feedback frame carries space-time block coding type indication information; and determining, by the transmitting device according to the space-time block coding type indication information, information about use of space-time block coding by a data frame related to the link adaptation feedback frame, and selecting, according to the use information, a space-time stream, and a modulation and coding scheme used when the transmitting device sends a data frame. Through the embodiments of the present invention, and according to the use information, the transmitting device may select the space-time stream, and the MCS used when the transmitting device sends a data frame, thereby improving link performance.

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-userdata 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.
