    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: A data transmission method and apparatus, and a non-transitory computer-readable storage medium are disclosed. The data transmission method may include: sending, by a first communication node, a radio frame comprising indication information to a second communication node, wherein the second communication node is associated with a third communication node, the third communication node and the first communication node perform joint transmission, and the indication information is configured to instruct a fourth communication node other than the second communication node, after receiving the radio frame, to determine whether to compete for channel access according to the indication information.

    Abstract: Provided are a data sending and receiving method and apparatus and a storage medium. The methods include sending a wireless signal that includes a trigger frame to one or more second communication nodes. The trigger frame is configured to trigger one or more second communication nodes to start transmission. The wireless signal carries at least one of first identifier information, second identifier information or third identifier information. The first identifier information is used to identify the sender of the trigger frame. The second identifier information is used to identify the receiver of the trigger frame. The third identifier information is used to identify that the trigger frame is configured to trigger the second communication node to start transmission.

    Abstract: Provided are a method and a device for sending traffic indication information. In the method, an AP sends a radio frame to multiple STAs associated with the AP, wherein the radio frame carries an indication field, and the indication field is used to indicate whether the radio frame carries traffic indication virtual bitmap information. According to the technical solution provided, in the case where the AP has no unicast cache data for any station, multiple STAs associated with the AP can know whether the AP has their respective unicast cache data to be sent.
