Abstract: Provided are methods and devices for transmitting a frame in a network. The method includes: setting, by a sending station, a media access control (MAC) frame header of a MAC frame, wherein the MAC frame header includes at least one bit for indicating whether the MAC frame header adopts an optimized MAC header format, the optimized MAC frame header format referring to a MAC frame format in which only necessary frame header information is reserved (S302); sending, by the sending station, the MAC frame to a receiving station (S304). The present disclosure not only ensures correct sending and receiving of a frame, but also effectively reduces the overhead of the frame header.

Abstract: Provided are a radio frame sending method and apparatus. In the method, when entering an awake state from a doze state, a station selects a pre-defined access category or an access category which is pre-negotiated with a centre station to contend for a wireless channel. Afterwards, the station sends a radio frame to the centre station via the wireless channel obtained through the contention, and then notifies the centre station to send buffered data to the station. The method and apparatus can be applied to flexibly and dynamically regulate an access category used for contending for a wireless channel when a station sends a radio frame which is used for notifying a centre station to send buffered data to the station.

The method includes that the wireless STA acquires a transmission ending moment of a wireless frame when selecting to refuse or drop the wireless frame and not updating a locally stored Network Allocation Vector (NAV); and the wireless STA accesses the channel when the transmission of the wireless frame is ended and a preset condition is met. According to the disclosure, a collision problem may happen to the wireless STA, and the wireless STA can access the channel only when the preset condition is determined to be met after the transmission of the wireless frame is ended, so that the problem of transmission collision with a hidden STA during the wireless frame transmission of the wireless STA is solved.
