Abstract
A power saving communication mechanism can be implemented on an access point and on a connected WLAN device in a wireless communication network so that the connected WLAN device transmits uplink data frames in response to receiving a trigger frame from the access point. The access point determines a number of connected wireless network devices in the wireless communication network and a number of power save intervals to be implemented in each beacon interval. Additionally, the access point can vary a trigger frame transmission sequence according to which trigger frames are transmitted to connected WLAN devices. The access point transmits the trigger frame to each connected WLAN device to request transmission of uplink data frames based on the trigger frame transmission sequence. The power saving communication mechanism can improve throughput, facilitate conservation of radio resources, and reduce power consumption.
