A wireless network interface of a first client station negotiates with an access point a first component channel of an operating channel via which the first client station is to receive wakeup frames from the access point. A wakeup radio of the first client station receives a wakeup packet from the access point. The wakeup packet spans the operating channel, which comprises at least four component channels, and one or more of the component channels within the operating channel are punctured so that the access point does not transmit the wakeup packet in the one or more component channels that are punctured. The wakeup packet includes a first wakeup frame for the first client station in the first component channel and one or more respective second wakeup frames for one or more second client stations in one or more respective second component channels.

Device, system, and method for multi-link tunneled direct link setup (TDLS) setup

A communication device performs a first backoff operation with a first backoff counter to determine when to transmit a first packet in a first frequency, and performs a second backoff operation with a second backoff counter to determine when to transmit a second packet in a second frequency segment. In connection with the first backoff counter expiring, the communication device transmits the first packet in the first frequency segment. In connection with the second backoff counter expiring, the communication device transmits the second packet in the second frequency segment simultaneously with transmitting the first packet in the first frequency segment. In response to determining that transmission of the first packet in the first frequency segment failed, the communication device increases a first contention window for a retransmission of the first packet, and does not adjust the second contention window for a next transmission in the second frequency segment.

A communication device generates a first packet and a second packet. The first packet includes a first physical layer (PHY) preamble having: a first legacy signal field (L-SIG) having first duration information that indicates a first duration of the first packet; and first non-legacy signal field information having first modulation information that indicates a first modulation used in the first packet. The second packet includes a second PHY preamble having: a second L-SIG having second duration information that indicates a second duration of the second packet, wherein the second duration is different than the first duration; and second non-legacy signal field information having second modulation information that indicates a second modulation used in the second packet, wherein the second modulation is different than the first modulation. The communication device simultaneously transmits the first packet in a first frequency segment and the second packet in a second frequency segment.

The first communication device transmits a first packet to a third communication device that is configured to process packets that conform to the first PHY protocol and packets that conform to the second PHY protocol. The first packet indicates that the one or more second communication devices neighboring the first communication device are not capable of processing packets that conform to the second PHY protocol to inform the third communication device of the one or more second communication devices.
