    Abstract: Methods, apparatuses, and computer readable media are disclosed to signal a packet configuration. A HEW device to signal a packet configuration may include circuitry. The circuitry may be configured to generate a HE packet comprising a legacy signal field (L-SIG) followed by one or more HE signal fields and include in the L-SIG the packet configuration of the HE packet to signal to a second HEW device. The circuitry may configure a length field of the L-SIG to be a one or two modulo of three (MOD 3) to indicate the HE packet. The length field of the L-SIG may indicate that the HE packet includes a portion that has a one-quarter size subcarrier. The circuitry may set the length field of the L-SIG to be 1 mod 3 to indicate a first type of HE packet and to be 2 mod 3 to indicate a second type of HE packet.

    Abstract: Apparatuses, methods, and computer readable media are disclosed. A STA to detect a HE SIG may be configured to detect the HE SIG based on at least one from the following group: a flipped reserved bit, a scrambled portion of the HE SIG, and a rotation of a signal constellation of the HE SIG different than legacy rotations of: a rotation of a first signal constellation and no rotation of a second signal constellation, and no rotation of the first signal constellation and a rotation of the second signal constellation. The STA may determine that a reserved bit is the flipped reserved bit based on a bit being reversed from a legacy standard. The STA may unscramble a received signal field, determine whether a CRC indicates the HE-SIG contains errors, and if the CRC indicates there are no errors, then determine that the signal field is the HE SIG.

    Abstract: Methods, apparatuses, and computer readable media include an apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to decode a legacy preamble of a physical layer (PHY) protocol data unit (PPDU), determine whether the legacy preamble comprises an indication that the PPDU is an extremely-high throughput (EHT) PPDU, and in response to the determination indicating the PPDU is the EHT PPDU, decode the EHT PPDU. Some embodiments determine a spatial stream resource allocation based on a row of a spatial configuration table, a row of a frequency resource unit table, a number of stations, and location of the station relative to the number of stations in user fields of an EHT-signal (SIG) field. To accommodate 16 spatial streams, some embodiments extend the length of the packet extension field, extend signaling of a number of spatial streams, and/or extend a number of EHT-SIG symbols.

    Abstract: Methods, computer readable media, and wireless apparatuses are disclosed for a TXOP duration field. An apparatus is disclosed comprising processing circuitry configured to: encode a first high efficiency (HE) physical-layer convergence procedure (PLCP) protocol data unit (PPDU) comprising a transmission opportunity (TXOP) duration field in a first physical-layer portion of the first HE PPDU. The processing circuitry may be further configured to set the TXOP duration field value to indicate a largest duration value representable by the TXOP duration field that is equal to or less than a duration value indicated by the first MAC duration field, if the first HE PPDU is to include a first media access control (MAC) duration field in a first MAC-layer portion of the first HE PPUU.

    Abstract: Methods, computer readable media, and wireless apparatuses are disclosed for a TXOP duration field disable setting in a HE preamble, such as HE-SIG-A. An apparatus of a wireless device can include processing circuitry configured to decode a HE PPDU received from a second wireless device, the HE PPDU including a first TXOP duration field in a PHY portion of the HE PPDU. The processing circuitry can detect whether the TXOP duration field includes a disable flag based on bit values of the TXOP duration field. The disable flag can indicate absence of duration information in the TXOP duration field. Upon detecting the disable flag, a response HE PPDU can be encoded for transmission to the second wireless device. The response HE PPDU can include a second TXOP duration field with a disable flag within a PHY portion of the response HE PPDU.
