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： This disclosure describes systems, methods, and devices related to over-puncture mitigation. A device may generate a frame comprising a payload having a payload size associated with a number of bits. The device may determine a low-density parity-check (LDPC) codeword size based on the payload size. The device may calculate a number of codewords based on the payload size. The device may calculate a number of shortening bits and a number of LDPC padding bits based on the number of codewords. The device may calculate a number of orthogonal frequency division multiplexing (OFDM) symbols for containing the number of codewords. The device may cause to send the frame with the number of OFDM symbols to a station device.

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.

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： This disclosure describes systems, methods, and devices related to an extreme high throughput (EHT) signaling structure. A device may establish a communication channel with one or more station devices (STAs). The device may generate an extreme high throughput signal field (EHT-SIG) of a header, wherein the EHT-SIG field comprises information associated with resource allocations (RUs). The device may generate a frame comprising the header. The device may assign a first RU to a first station device. The device may assign a second RU to the first station device, wherein the first RU or the second RU is an aggregation of a 26-tome RU and a neighboring RU. The device may cause to send the frame to the first station device.
