Low-Latency Communication in a WLAN

Abstract:

An electronic device may receive a frame associated with a second electronic device. This frame may include a MAC header with information specifying a request for a trigger or a trigger frame, and the information may include a suggested time interval during which the trigger or the trigger frame is to be provided and a requested resource allocation. For example, the MAC header may include an A-control field, and the A-control field may include the information or may include multiple A-MPDUs and one or more of the A-MPDUs (such as a last A-MPDU or all of the A-MPDUs) may include the information. Moreover, the time interval may begin at a previous transmission associated with the second electronic device, and the requested resource allocation may include a capacity. In response to the request, the electronic device may provide the trigger or the trigger frame addressed to the second electronic device.
