    Abstract: Techniques for sharing channel availability information using virtual sensing are disclosed. In one example, a wireless communication method includes receiving, by a wireless terminal, a message carrying a multi-channel occupancy information for multiple channels over a wireless communication medium and performing, by the wireless terminal, an access to the wireless communication medium by avoiding collisions using the multi-channel occupancy information.

    Abstract: A method for processing a network allocation vector (NAV) includes: terminating the receiving of a first radio frame when it is determined that a target receiving station of the first radio frame being received is not a first station; and updating an NAV of the first station or maintaining the NAV of the first station unchanged according to a remaining duration of the first radio frame and a first transmission opportunity duration carried in the first radio frame, where the remaining duration of the first radio frame is the transmission time used for transmitting the remaining part of the first radio frame after the receiving of the first radio frame is terminated. The technical solution solves the problem in the related art of collisions with hidden stations caused by an inaccurate NAV update in the existing art, thereby ensuring the accuracy of an NAV update and the fairness of transmission and channel contention, and reducing collisions among hidden stations.

    Abstract: Disclosed are a method and device for receiving the radio frame. The method comprises: a first functional entity of a station detects that a channel signal intensity reaches a preset threshold, and the first functional entity starts receiving a radio frame and sends an indication that a channel detection result is busy to a second functional entity of the station; the first functional entity determines that the station is not a target station for receiving the radio frame, and sends an indication of ending up receiving the radio frame to the second functional entity; and when transmission of the radio frame ends, the first functional entity sends an indication that the channel detection result is idle to the second functional entity. The disclosure provides a reception operation processing procedure of a station having the function of discarding the radio frame while not updating a network allocation vector (NAV).

    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.
