Meta patents method to pause and resume Wi-Fi power-saving schedules
Meta describes a system where a device sends a specific signal to tell another device to restart a pre-set schedule for waking up to check for data. This allows devices to pause their energy-saving sleep cycles and resume them later using a simple identifier in the communication frame.
In the filing’s own words
A device may include one or more processors. The one or more processors may generate a first frame including a first target wake time (TWT) identifier subfield. The one or more processors may determine whether a first broadcast TWT schedule is to be resumed. In response to determining that the first broadcast TWT schedule is to be resumed, the one or more processors may set the first TWT identifier subfield to a first identifier value identifying the first broadcast TWT schedule, such that a receiver device receiving the first frame with the first TWT identifier subfield is to resume the first broadcast TWT schedule. The one or more processors may wirelessly transmit, via a transmitter, the generated first frame to the receiver device.
What exactly they claim (claim 1)
1. A device comprising: one or more processors configured to: generate a first frame including a first target wake time (TWT) identifier subfield; determine whether a first broadcast TWT schedule is to be resumed; in response to determining that the first broadcast TWT schedule is to be resumed, set the first TWT identifier subfield to a first identifier value identifying the first broadcast TWT schedule, such that a receiver device receiving the first frame with the first TWT identifier subfield is to resume the first broadcast TWT schedule, and wirelessly transmit, via a transmitter, the generated first frame to the receiver device.
