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： Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. An AP may be configurable to operate as a master AP of a multi-AP group comprising the master AP and one or more satellite APs. The master AP may select, from the multi-AP group, a set of APs that is to communicate with a STA in accordance with joint processing. The master AP may allocate one or more spatial streams to each of the APs of the set of APs for a joint transmission of a null data packet (NDP) to the STA for channel sounding. The master AP may transmit an NDP announcement (NDPA) that indicates that the APs of the set of APs are to perform the joint transmission of the NDP.

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： An access-point station (AP) configured for communicating multi-user (MU) physical layer protocol data units (PPDUs) (MU-PPDUs) with plurality of non-AP stations (STAs) using dynamic channel switching may acquire a transmission opportunity (TXOP) on a channel comprising a primary channel and one or more non-primary channels. The AP may encode a channel switching indication frame that may request that at least some of the STAs temporarily switch from operating on the primary channel to operating on one of the non-primary channels. The AP may decode a response frame from each of the STAs that are indicated to switch. Each response frame may be received on the non-primary channel that an indicated STA is requested to switch to. For a downlink (DL) transmission, the AP may encode a DL MU-PPDU comprised of a plurality of PPDUs of different physical layer (PHY) types including at least a first PPDU for transmission on the primary channel to a first STA that had not been instructed to switch to a non-primary channel, and at least a second PPDU for transmission on one of the non-primary channels to a second STA that had been instructed to switch to one of the non-primary channels.

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： 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： Embodiments of an Extremely High Throughput Station (EHT STA) (STA1) configured for operating in a next-generation (NG) wireless local area network (WLAN) are described herein. In some embodiments, the EHT STA encodes a common signal field (SIG) (Coex-SIG) of an EHT PPDU to include a TXOP duration field. The TXOP duration field is more than seven bits to indicate an actual TXOP duration of a transmission from the EHT STA comprising the EHT PPDU transmitted to a second station (STA2). Decoding the TXOP duration field of the EHT PPDU by a third-party station (STA4) causes the third-party station (STA4) to defer a transmission until after an end of the transmission from the second station (STA2).
