Abstract: An access point station (AP) generates a trigger frame (TF) for transmission to two or more non-AP stations (STAs) or groups of STAs. The trigger frame may allocate resource units (RUs) for a trigger-based (TB) transmission to the two or more STAs. The AP may encode the trigger frame to include a Common Info field followed by one or more Special User Info fields. The Common Info field and the one or more Special User Info fields and may be encoded to solicit (i.e., trigger) a trigger-based (TB) Frequency Aggregated Physical layer Protocol Data Unit (PPDU) (FA-PPDU) that includes more than one PPDU of at least two different physical layer (PHY) types from the two or more STAs or groups of STAs. The different PHY types may include high-efficiency (HE), Extremely High Throughput (EHT), Ultra-High Rate (UHR), and UHR+. Accordingly, an AP can trigger a FA-PPDU that includes TB PPDUs of different PHY types.

Abstract: Logic may define one or more wake-up preambles suitable for high data rates for a wake-up radio (WUR) packet. Logic may define wake-up preamble with different counts of symbols. Logic may generate a wake-up preamble as an on-off keying (OOK) signal. Logic may generate and receive a wake-up preamble that signals a high data transmission rate with respect to data rates defined for WUR packet transmissions. Logic may generate or receive a preamble that signals a rate of transmission of the WUR packet as 250 kilobits per second. Logic may transmit or receive bits of the wake-up preamble as two microsecond orthogonal frequency-division multiplexing (OFDM) based pulses, wherein each two microsecond OFDM based pulse is based on a 32-point Fast Fourier Transform (FFT) in a 20 Megahertz (MHz) bandwidth, with a subcarrier spacing of 625 Kilohertz (KHz) to produce six subcarriers in a four MHz bandwidth.

Abstract: Embodiments of an Extremely High Throughput Station (EHT STA) (STA1) configured for operating in a next-generation (NG) wireless local area network (WLAN) are described herein. In some embodiments, the EHT STA encodes a common signal field (SIG) (Coex-SIG) of an EHT PPDU to include a TXOP duration field. The TXOP duration field is more than seven bits to indicate an actual TXOP duration of a transmission from the EHT STA comprising the EHT PPDU transmitted to a second station (STA2). Decoding the TXOP duration field of the EHT PPDU by a third-party station (STA4) causes the third-party station (STA4) to defer a transmission until after an end of the transmission from the second station (STA2).

Abstract: Logic may enable client devices or access points to relay medium access control (MAC) frames through a Wireless Fidelity (Wi-Fi) Direct network such as a network of Peer-to-Peer (P2P) connections to extend the wireless range of the devices or access points beyond the transmission range of the individual devices or access points.

Logic may enable relaying to avoid a full mesh technology such as is defined in IEEE 802.11s, since the full mesh technology may contain too many features that are not required for a simple or a static network configuration of such embodiments.
