Samsung patents Wi-Fi router signal to tell devices when it is busy
This filing describes a method where a Wi-Fi router (access point) sends a specific control message to connected devices. The message tells the devices exactly when the router will be too busy to handle new data transmissions, helping them wait their turn.
In the filing’s own words
A method performed by an access point (AP) for indicating unavailability information in a wireless local area network (WLAN) communication system is provided. The method includes determining dynamic unavailability time information for a period during which the AP is unable to utilize a duration of transmission opportunity and the dynamic unavailability time information includes at least one of a start time of unavailability time slot or a duration of unavailability; indicating the dynamic unavailability time information in a control frame; and transmitting, to at least one non-AP station, the control frame.
