Signaling a synchronization frame transmission request

摘要

Various embodiments of the invention describe a format and procedure for a wireless communication device to request a network controller to transmit a synchronization frame so that the device may synchronize its communication activities with the network controller. This operation may be used in various types of wireless networks, such as but not limited to those conforming to IEEE standard 802.11ah.

主权项

1. A first wireless communication device having a processor, a memory, and a radio, the first device configured to:
transmit a sync request frame between the first wireless communication device and a second wireless communication device, the sync request frame formatted as a request to transmit a sync frame; and receive the sync frame; wherein the sync request frame is transmitted just before the first device enters a low power state and requests transmission of a sync frame after the first device exits low power state.
