摘要： An extremely high-throughput (EHT) station (STA) may encode an EHT PPDU for transmission on a plurality of subchannels. The EHT STA may determine a spectral mask to apply to the EHT PPDU prior to transmission of the EHT PPDU. When preamble puncturing is performed, the EHT STA may apply an overall spectral mask to the EHT PPDU prior to transmission. The overall spectral mask may be based on an interim spectral mask and a preamble-puncture spectral mask. The subchannels may be in a 6 GHz band and the EHT STA may determine if preamble puncturing is to be performed for one or more of the subchannels based on a presence of incumbents in the one or more of the subchannels, although the scope of the embodiments is not limited in this respect.

摘要： Embodiments of an access point (AP) station (STA) configured for operating in a next-generation (NG) wireless local area network (WLAN) (i.e., EHT) are generally described herein. In some embodiments, a comb resource unit (RU) structure may be used to distribute tones of an RU across a wider bandwidth for narrow RU power spectral density (PSD) boosting for longer-range transmission in EHT to meet ETSI and/or FCC limitations.

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： 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 mechanisms for performing rate matching in low-density parity check (LPDC) codes in a wireless network. A device may generate an Aggregated Media Access (MAC) Protocol Data Unit (AMPDU) payload having an AMPDU payload size associated with a number of bits. The device may omit pre-Forward Error Correction (FEC) padding of the AMPDU payload at a MAC layer by indicating the AMPDU payload size in a physical layer (PHY)-specific preamble. The device may then generate the PHY-specific preamble comprising the AMPDU payload size without the pre-FEC padding. The device may also calculate a number of Orthogonal Frequency Division Multiplexing (OFDM) symbols for containing the number of bits and transmit the PHY-specific preamble and the number of OFDM symbols to a station device.

摘要： For example, a wireless communication Station (STA) may be configured to determine a data field processing setting for a data field of a Physical Layer (PHY) Protocol Data Unit (PPDU) such that a padding parameter value corresponding to the data field processing setting does not exceed a padding parameter threshold, wherein the data field processing setting includes at least one of a Modulation and Coding Scheme (MCS) index or a channel Bandwidth (BW) setting, wherein the padding parameter value corresponding to the data field processing setting is based on a number of pre Forward Error Correction (FEC) (pre-FEC) pad bits according to the data field processing setting; and to encode the data field according to a FEC coding using the number of pre-FEC pad bits according to the data field processing setting.

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： 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.
