Abstract

Generally discussed herein are devices and methods for providing devices with packet duration and/or transmit and/or receive time frame information. An apparatus can include processing circuitry and transceiver circuitry configured to generate a packet for transmission on one or more sub-channels for one or more stations, each sub-channel comprising a common wake-up physical synchronization, a station dedicated wake-up preamble, and a packet length, wherein each station dedicated wake-up preamble comprises a wake-up identifier for a station of the one or more stations and the packet length indicates a duration of the packet, and wherein a station of the one or more stations includes a receive bandwidth of less than twenty megaHertz, and transmit the packet to the one or more stations during a transmission opportunity (TXOP) obtained by the AP.

Dependent claims

An apparatus of a high-efficiency (HE) access point (AP), the apparatus comprising:

processing circuitry configured to generate a packet for transmission on one or more sub-channels for one or more stations, the packet comprising a common wake-up physical synchronization for processing by a physical layer of the one or more stations, a station dedicated wake-up preamble for processing by one of (1) a physical layer and (2) a physical layer and a media access control (MAC) layer, and a packet length, wherein each station dedicated wake-up preamble comprises a wake-up identifier for a station of the one or more stations and the packet length indicates a duration of the packet, and wherein a station of the one or more stations is capable of decoding a receive bandwidth of less than twenty megaHertz;
and
transceiver circuitry configured to transmit the packet to the one or more stations during a transmission opportunity (TXOP) obtained by the AP.

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors, the instructions to configure the one or more processors to cause a wireless local-area network device to:

generate a packet for transmission on one or more sub-channels for one or more stations, the packet comprising a common wake-up physical synchronization for processing by one of a physical layer of the one or more stations, a station dedicated wake-up preamble for processing by one of (1) a physical access layer and (2) a physical access layer and a media access control (MAC) layer, and a packet length, wherein each station dedicated wake-up preamble comprises a wake-up identifier for a station of the one or more stations and the packet length indicates a duration of the packet, and wherein a station of the one or more stations is capable of decoding a receive bandwidth of less than twenty megaHertz;
and
transmit the packet to the one or more stations during a transmission opportunity (TXOP) obtained by the AP.

A method performed by a wireless local-area network device, the method comprising:

generating a packet for transmission on one or more sub-channels for one or more stations, the packet comprising a common wake-up physical synchronization for processing by a physical layer of the one or more stations, a station dedicated wake-up preamble for processing by one of (1) a physical access layer and (2) a physical access layer and a media access control (MAC) layer of the one or more stations, and a packet length, wherein each station dedicated wake-up preamble comprises a wake-up identifier for a station of the one or more stations and the packet length indicates a duration of the packet;
and
transmitting the packet to the one or more stations during a transmission opportunity (TXOP) obtained by the AP.
