Abstract: For example, a wireless communication station (STA) may be configured to generate a plurality of encoded-modulated data streams based on a data field of a PPDU to be transmitted over a channel BW. For example, the plurality of encoded-modulated data streams may be configured based on a plurality of channel BW segments in the channel BW. For example, the plurality of encoded-modulated data streams may include a first encoded-modulated data stream according to a first Modulation and Coding Scheme (MCS) corresponding to a first channel BW segment, and a second encoded-modulated data stream according to a second MCS, e.g., different from the first MCS, corresponding to a second channel BW segment. For example the STA may be configured to transmit a plurality of transmissions based on the plurality of encoded-modulated data streams over the plurality of channel BW segments.

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 two microsecond pulses of orthogonal frequency-division multiplexing (OFDM) symbols in a four megahertz (MHz) bandwidth. Logic may generate and receive a high data rate (HDR) WUR preamble or a low data rate (LDR) WUR preamble. The HDR preamble may signal a data rate of 250 kilobits per second and the LDR preamble may signal a data rate of 62.5 kilobits per second. The HDR preamble bit count may be twice a bit count of the LDR preamble. The HDR preamble may be 32 bits. The duration of transmission of the HDR may be 64 microseconds and duration of transmission of the LDR may be 128 microseconds.

Abstract: This disclosure describes systems, methods, and devices related to an enhanced hybrid automatic repeat request (HARQ). A device may determine two or more HARQ medium access control (MAC) frames. The device may determine a difference between a first number of bits of a physical layer (PHY) codeword and a second number of bits of a first HARQ MAC frame of the two or more HARQ MAC frames. The device may generate, based on the difference, a third number of bits, wherein the first number of bits is equal to a sum of the second number of bits and the third number of bits. The device may generate an aggregated MAC frame comprising the first HARQ MAC frame, the third number of bits, and a second HARQ MAC frame of the two or more HARQ MAC frames. The device may send the aggregated MAC frame.

Abstract: This disclosure describes systems, methods, and devices related to generating a wake up receiver (WUR) transmit waveform. A device may determine one or more symbols bit sequence of a wake up receiver (WUR) frame to be sent to a first station device capable of decoding the bit sequence. The device may determine a first symbol of the one or more symbols, wherein the first symbol is associated with an ON state. The device may determine a second symbol of the one or more symbols, wherein the second symbol is associated with the ON state. The device may generate a first on-off keying (OOK) waveform associated with the first symbol. The device may generate a second OOK waveform associated with the second symbol, wherein the second OOK waveform is different from the first OOK waveform. The device may cause to send the WUR frame to the first station device based on the first OOK waveform and the second OOK waveform.

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).
