摘要： For example, a transmitter may be configured to assign a stream of encoded data bits of a Physical layer (PHY) Protocol Data Unit (PPDU) to one or more sequences of encoded bit blocks for one or more spatial streams based on an Unequal Modulation and Coding Scheme (MCS) (UEM) assignment including an assignment of a plurality of MCSs to a plurality of frequency sub-blocks for the one or more spatial streams. For example, the transmitter may be configured to assign the one or more sequences of encoded bit blocks to the plurality of frequency sub-blocks for the one or more spatial streams.

摘要： A station (STA) configured for operation in a wireless local area network (WLAN) may implement an unequal Modulation and Coding Scheme (MCS) for Probabilistic Constellation Shaping using first and second shaping encoders. The first shaping encoder may encode a first segment of input bits for a first modulation order and generate a first shaped bit stream and the second shaping encoder may encode a second segment of input bits for a second modulation order to generate a second shaped bit stream. A first QAM symbol stream may be generated at least from the first shaped bit stream and from parity bits using the first modulation order and a second QAM symbol stream may be generated at least from the second shaped bit stream and from parity bits using the second modulation order. The STA may generate the parity bits from the first and second shaped bit streams with one or more LDPC encoders and may transmit the first and second QAM symbol streams within a PPDU.

摘要： For example, a non Access Point (AP) (non-AP) station (STA) may be configured to operate in a 40 Megahertz (MHz) operating mode, as a 40 MHz operating non-AP STA, which supports a 40 MHz operating channel width. For example, the 40 MHz operating non-AP STA may be capable to process allocation information from an AP to identify a Resource Unit (RU) or Multiple RU (MRU) (RU/MRU) allocated to the 40 MHz operating non-AP STA within the 40 MHz operating channel width; and to communicate data over the RU/MRU allocated to the 40 MHz operating non-AP STA as part of a wider bandwidth Orthogonal Frequency Division Multiple Access (OFDMA) transmission over a channel bandwidth of at least 80 MHz.

摘要： For example, a wireless communication device may be configured to generate, transmit, receive and/or process one or more transmissions of an Extra Range (ER) Physical layer (PHY) Protocol Data Unit (PPDU), which may be configured to be decodable by ER wireless communication stations (STAs). For example, the ER PPDU may include an ER preamble. For example, the ER preamble may be configured to include an ER STF (ER-STF), an ER LTF (ER-LTF) after the ER-STF, and an ER Signal (ER-SIG) field after the ER-LTF. In one example, the ER PPDU may include a non-ER preamble, which may be configured to be decodable by non-ER STAs, which may not be capable of decoding the ER preamble.

摘要： Embodiments of a station (STA) and method of communication are generally described herein. The STA may be included in a first plurality of STAs affiliated with a first multi-link logical entity (MLLE). A plurality of links may be established between the first MLLE and a second MLLE, wherein the second MLLE may be affiliated with a second plurality of STAs. The STA may receive a first subset of a sequence of MAC protocol data units (MPDUs). A second subset of the sequence of MPDUs may be transmitted by another STA of the first plurality of STAs. The STA may transmit a block acknowledgement (BA) frame that includes: a number of BA bitmaps, configurable to values greater than or equal to one; and BA control information for each of the BA bitmaps.

摘要： Embodiments of low-power wake-up packet generation are generally described herein. A wireless device modulates an LP-WUR (low-power wake-up radio) bit sequence with an LP-WUR pulse to obtain a plurality of modulated LP-WUR signals, each modulated LP-WUR signal having a 1× symbol duration. The wireless device multiplexes, in a time domain, an OFDMA (orthogonal frequency division multiple access) signal with a 4× symbol duration with four modulated LP-WUR signals, to generate a multiplexed signal. The wireless device encodes for transmission of the multiplexed signal to a peer device to wake up a WLAN (wireless local area network) radio of the peer device and to another device with an OFDMA signal.

摘要： A physical layer protocol data unit (PPDU) may include legacy preamble fields followed by a universal signal field (U-SIG). For an extended range (ER) transmission, the U-SIG is encoded to indicate via a bit whether the PPDU is an ER PPDU or a non-ER PPDU. When the U-SIG is encoded to indicate that the PPDU is an ER PPDU, the PPDU may include ER preamble fields following the U-SIG and an ER data field following the ER preamble fields. The ER preamble fields may comprise pre-ER modulated fields followed by ER modulated fields. The pre-ER modulate fields may comprise an ER short training field (ER-STF) followed by an ER long training field (ER-LTF) followed by an ER signal field (ER-SIG). The ER modulated fields may comprise at least the ER data field.

摘要： An apparatus and method of signaling coding type is disclosed. The coding types include binary convolutional coding (BCC), legacy lifted Low-Density Parity Check (LDPC) code, and lifted LDPC code having a length that is a multiple of the maximum legacy LDPC code. The number of bits used to indicate the coding type in a User Info field depends on whether multiple lifted LDPC codes are available for encoding, whether the lifted LDPC code is an optional coding type, or a payload size. The frame containing the User Info field is transmitted to another STA and the response contains a payload encoded using the indicated coding type.

摘要： An access point station (AP) communicates with a plurality of non-AP stations (STAs) within a synchronized transmission opportunity (S-TXOP). The S-TXOP may comprise an S-TXOP trigger followed by a plurality of S-TXOP slots. After transmission of the S-TXOP trigger, the AP may encode, for transmission within an S-TXOP slot, a downlink (DL) multi-user physical layer protocol data unit (DL MU-PPDU). The DL MU-PPDU may include a preamble followed by a data field. To indicate that a previously signaled resource unit (RU) allocation is to be used during the S-TXOP slot, the AP may encode the preamble to include an allocation ID of the previously signaled RU allocation in a signal field (SIG) of the preamble and to include a SIG-2 presence indicator to indicate that a second signal field (SIG-2) is not included in the preamble.
