A wireless communication system includes a wireless device, an Access Point (AP) device, and a controller. The wireless device includes a first processor having a counter. The controller is configured to send a learn idle time command through the AP device and to the processor. The processor is configured to cease any transmission through the AP device and start the counter after receiving the learn idle time command, and is configured to receive a message indicative of no activity by the wireless device from the AP device, and estimate an AP idle time based on the counter.
