More Information
Summary:Examples of triggered single user (SU) transmissions are described. In an example, an access point (AP) may send a SU trigger frame to a client device for initiating a data transmission by the client device. The AP may detect whether the data transmission is initiated within the Short Interframe Spacing (SIFS) after the SU trigger frame is sent. Responsive to detecting that the data transmission is not initiated within the SIFS, the AP waits for the client device to initiate the data transmission within a predefined time interval after the SIFS. Responsive to detecting that the data transmission is not initiated within the predefined time interval, the AP repurposes the channel access after the predefined time interval is elapsed. Responsive to detecting that the data transmission is initiated within the predefined time interval, the AP repurposes channel access after one of an expiration of a maximum transmission opportunity (TXOP) duration and a completion of the data transmission, whichever is earlier.
