In accordance with unscheduled automatic power save delivery (U-APSD) mechanisms, an access point typically creates an unscheduled service period irrespective of availability of downlink data packets for a WLAN device. This can result in a large overhead that can limit the performance and throughput of the WLAN device. Functionality can be implemented on the access point and/or on the WLAN device so that the access point suppresses creating the service period (and transmitting an indication of an end of the service period) when there are no downlink data packets for the WLAN device. In some implementations, configuring the access point to defer creating the service period until it is determined that the WLAN device has transmitted all scheduled uplink data packets, or until the access point has available downlink data, can facilitate conservation of radio resources, and reduce power consumption. |
