    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: Multiple wireless devices in a network perform full duplex communication in which the transmission path and receiving path are spatially separated to allow simultaneous transmission and receiving. The wireless devices can either be controlled using a centralized, or point, coordination function or a distributed coordination function. A full-duplex wireless device senses the medium during transmission by itself and selectively continues the transmission when a signal is sensed on the medium. A full-duplex wireless device measures signal being transmitted by its transmitter and estimates parameters that can be used to cancel the contribution of the locally transmitted signal to the locally received signal concurrently being received during the transmission. The transmit antenna and the receive antenna of a full-duplex wireless device can be configured to be spatially isolated from each other to minimize interference between the antenna functions.

    Abstract: A transmitting wireless device provides channel access information to a receiving wireless device for the receiving wireless device to make a determination of when to transmit and what transmissions parameters to use for the transmission. The channel access information may be used differently by wireless devices operating in a basic service set and an overlapping basic service set. Channel access information may include fields indicative of transmission power used, signal to noise ratio headroom available, and so on. Channel access information may be generated and transmitted at the PHY layer of an implementation, thus providing a fast delivery to the receiving wireless device.

    Abstract: The present document provides a method for avoiding downlink data collision, an Access Point (AP) and a Station (STA). The method for avoiding downlink data collision includes: an AP receiving a radio frame for inquiring whether the AP has a Bufferable Unit (BU) of an STA transmitted by the STA; and after determining that there is a BU of the STA and the BU is larger than a predetermined threshold, the AP exchanging radio frames with the STA to reserve a channel, and transmitting the BU to the STA after succeeding in reserving the channel. The method can guarantee the fairness among various STAs and the reasonable utilization of channel resources, thus avoiding the collision; furthermore, the channel reservation frame transmitted by the AP can reserve a longer period of time, i.e. a plurality of BUs can be transmitted to the STA at a time, thus saving the link overhead.
