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： 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, an AP may be configured to set RU allocation information for a user STA in an RU allocation subfield of a user field for the user STA. For example, the RU allocation information for the user STA may indicate an RU allocation for a TB UL transmission from the user STA. For example, the AP may be configured to set a 7-bit UL MCS subfield, for example, after the RU allocation subfield, to indicate a first MCS and a second MCS for the user STA. For example, the first MCS may be assigned to a first UL resource of the RU allocation for the user STA, and the second MCS may be assigned to a second UL resource of the RU allocation for the user STA. For example, the AP may be configured to transmit a trigger frame including the user field for the user STA.

摘要： A station (STA) configured for operation in a WLAN may perform bit scrambling on input bits to generate scrambled input bits and may perform probabilistic constellation shaping using a shaping encoder on the scrambled input bits. The shaping encoder may encode a segment of the scrambled input bits for a modulation order and generate a shaped bit stream. In these embodiments, the STA may generate a QAM symbol stream with a QAM modulator. The QAM symbol stream may be generated at least from the shaped bit stream and from parity bits using the modulation order. The STA may generate the parity bits from the shaped bit streams with a forward-error correction (FEC) encoder and may transmit the QAM symbol stream within a physical layer protocol data unit (PPDU). To address a potential byte boundary shift caused a decoding error at a receiving station, the STA may modify performance of the bit scrambling when probabilistic constellation shaping is performed.

摘要： This disclosure describes systems, methods, and devices related to enhanced tone allocation. A device may schedule a number of station devices to be included in a physical layer (PHY) protocol data unit (PPDU) for a multiple-user multiple-input multiple-output (MU-MIMO) transmission. The device may limit a number of resource units (RUs) to be used in the PPDU for the MU-MIMO transmission. The device may use a minimum RU size to be at least 242 tones for the MU-MIMO transmission. The device may cause to send the PPDU to the number of station devices.

摘要： For example, an Access Point (AP) may be configured to set a user specific field in a Signal (SIG) field. For example, the user specific field may be configured for a user of a plurality of users in a Multi-User (MU) Multiple-Input-Multiple-Output (MIMO) (MU-MIMO) allocation. For example, the user specific field for the user may include an Unequal Modulation and Coding Scheme (MCS) (UEM) information subfield configured to indicate an assignment of a plurality of MCSs for the user. For example, the user specific field for the user may include a spatial configuration subfield configured to indicate a number of spatial streams for the user and a total number of spatial streams in the MU-MIMO allocation. For example, the AP may be configured to transmit a Physical layer (PHY) Protocol Data Unit (PPDU) including the SIG field.

摘要： This disclosure describes systems, methods, and devices related to tone mapping for a high-efficiency (HE) trigger-based (TB) null data packet (NDP) feedback physical layer protocol data unit (PPDU). A device may identify a frame received from a second device. The device may determine, based on the frame, a resource unit allocated to the device, wherein the resource unit is associated with a 20 MHz sub-channel of a bandwidth. The device may determine, based on the resource unit and the bandwidth, tones associated with a HE short training field (HE-STF) of a HE TB NDP feedback PPDU. The device may send the HE TB NDP feedback PPDU to the second device in the 20 MHz sub-channel, wherein the HE TB NDP feedback PPDU includes the tones.
