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： 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： An access point (AP) configured for multi-AP coordinated beamforming (CBF) and multi-AP joint transmission (JT) in an Extremely High Throughput (EHT) wireless local area network (WLAN), when operating as a master AP (AP1) in a multi-AP network, is configured to encode a null data packet announcement (NDPA) frame for multi-AP channel sounding. The NDPA is configured for transmission to a second AP (AP2) and a plurality of stations (STAs) of an EHT group. The NDPA may be encoded to have an information field indicating whether a sounding sequence type is for JT channel sounding or CBF channel sounding. The NDPA may further be encoded to include fields identifying the APs participating in the channel sounding. In these embodiments, the channel sounding sequence for JT can be reused for the channel sounding on CBF.

摘要： Multi-link device (MLD) security association (SA) query and query response procedures are described. Any of the links between an access point (AP) MLD and a non-AP MLD may be used to initiate association, reassociation, or disassociation procedures using the SA query requests and responses. The SA query request or response from one of the stations (STAs) associated with the MLD is sent to a corresponding linked one of the STAs associated with the other MLD. The SA request or response is addressed to the other MLD rather than the STA of the other MLD. Retry timeouts and maximum timeouts for resending SA query requests are set by the AP MLD and the same across each of the links.

摘要： An extremely high throughput (EHT) device configured for operation in an EHT network may negotiate a block acknowledge (BA) agreement with another EHT device including negotiate a maximum size of a receive reordering buffer to be up to one-third of sequence number (SN) space The SN space may have a predetermined maximum number of 4096 entries and may be signaled by twelve bits. When a larger reordering buffer is needed, the EHT STA may be configured to negotiate a larger reordering buffer size and additional SN space and may be configured to add additional signalling bits to signal the additional SN space.

摘要： An extremely high-throughput (EHT) station (STA) is configured for transmission of a control response frame for rate selection. In response to a frame carried in an EHT PPDU soliciting a control response frame, the EHT STA may calculate a duration of a non-HT PPDU containing the control response frame sent at a primary rate. The EHT STA may also encode a high-efficient (HE) single-user (SU) PPDU (HE SU PPDU) for transmission to carry the solicited control response frame when a transmit time of the encoded HE SU PPDU is less than the calculated duration of the non-HT PPDU, or encode an EHT PPDU for transmission to carry the solicited control response frame when a transmit time of the encoded EHT PPDU is less than the calculated duration of the non-HT PPDU. A reduction in overhead may be achieved by using an HE SU PPDU or an EHT PPDU instead of a non-HT PPDU to carry a solicited control response frame.

摘要： For example, a wireless communication station (STA) may be configured to set a Message Integrity Code (MIC) in a MIC field to protect contents of a control frame according to a Galois Message Authentication Code with 256-bit cipher-key (GMAC-256) protection mechanism. For example, the MIC may be based on a Packet Number (PN). For example, a size of the MIC field may be less than 16 bytes. For example, the STA may be configured to set a PN field based on the PN. For example, a size of the PN field may be less than 6 bytes. For example, the STA may be configured to transmit the control frame including the MIC field and the PN field.
