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.

Abstract: In a wireless network, full duplex communication is established using a half-duplex mechanism. During a full duplex communication opportunity, a first quantum of data is transmitted from a first station to a second station and a second quantum of data is received by the first station from the second station. The full duplex transmission opportunity is implicitly or explicitly established and ended using a transmission mechanism understood by half duplex wireless stations.

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.
