Abstract
Wireless communication in a wireless network comprises a wireless device communicating power save capability information with a coordinator during a discovery state. A beacon that indicates a configuration state is received by the wireless device. Configuration status information is sent to the coordinator. A configuration request is received by the wireless device from the coordinator for entering or exiting the power save mode.
Claims28
A method of wireless communication, comprising:
- communicating, by a wireless device, power save capability information with a coordinator during a discovery state;
- receiving, by the wireless device, a low latency (LL) beacon indicating a configuration state, the LL beacon including a modified LL frame comprising an additional sleep control field that includes an indication for a sleep command or a wake up command, and the additional sleep control field includes sub-fields comprising indications of application of the sleep command or the wakeup command for multiple wireless devices;
- sending configuration status information to the coordinator;
- and
- receiving, by the wireless device, a configuration request command frame for entering or exiting the power save mode.
2 more elements
A wireless device, comprising:
- a media access control (MAC) layer;
- a memory storing instructions;
- and
- at least one processor configured to execute the instructions to perform operations including power save processing to communicate power save capability information with a coordinator during a discovery state, to send configuration status information to the coordinator based on a received low latency (LL) beacon indicating a configuration state, the LL beacon including a modified LL frame comprising an additional sleep control field that includes an indication for a sleep command or a wake up command, the additional sleep control field comprises sub-fields for indications of application of the sleep command or the wakeup command for multiple wireless devices, and to receive a configuration request command frame for entering or exiting the power save mode.
1 more element
A wireless coordinator, comprising:
- a Physical Layer (PHY) configured to provide wireless communication over a wireless communication channel;
- and
- a media access control (MAC) layer configured to manage transmissions for multiple wireless stations over a wireless channel,
- wherein the coordinator is configured to receive power save capability information from a wireless device during a discovery state, to send a low latency (LL) beacon including a request for configuration status information, the LL beacon including a modified LL frame comprising an additional sleep control field that indicates a sleep command or a wake up command to the wireless device, the additional sleep control field comprises sub-fields for indications of application of the sleep command or the wakeup command for multiple wireless devices, and to receive a configuration status from the wireless device, and to send a configuration request command frame to the wireless device for entering or exiting the power save mode.
