摘要： Embodiments of an AP and wake up radio (WUR) non-AP station (STA) are generally described herein. The AP may transmit a WUR packet to wake up a wireless local area network (WLAN) radio of the WUR non-AP STA. A non-WUR portion of the WUR packet may include legacy fields and a BPSK mark to spoof high throughput (HT) devices receiving the WUR packet. The AP may transmit the BPSK mark in a channel that includes a lower guard band, a transmission bandwidth, and an upper guard band. The AP may encode the BPSK mark in accordance with: on-off keying (OOK) modulation in a center portion of the transmission bandwidth; and orthogonal frequency division multiplexing (OFDM) in a remaining portion of the transmission bandwidth that excludes the center portion.

摘要： Embodiments of a station (STA) and method of communication are generally described herein. The STA may be included in a first plurality of STAs affiliated with a first multi-link logical entity (MLLE). A plurality of links may be established between the first MLLE and a second MLLE, wherein the second MLLE may be affiliated with a second plurality of STAs. The STA may receive a first subset of a sequence of MAC protocol data units (MPDUs). A second subset of the sequence of MPDUs may be transmitted by another STA of the first plurality of STAs. The STA may transmit a block acknowledgement (BA) frame that includes: a number of BA bitmaps, configurable to values greater than or equal to one; and BA control information for each of the BA bitmaps.

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).

摘要： Methods, apparatuses, and computer readable media include an apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to decode a legacy preamble of a physical layer (PHY) protocol data unit (PPDU), determine whether the legacy preamble comprises an indication that the PPDU is an extremely-high throughput (EHT) PPDU, and in response to the determination indicating the PPDU is the EHT PPDU, decode the EHT PPDU. Some embodiments determine a spatial stream resource allocation based on a row of a spatial configuration table, a row of a frequency resource unit table, a number of stations, and location of the station relative to the number of stations in user fields of an EHT-signal (SIG) field. To accommodate 16 spatial streams, some embodiments extend the length of the packet extension field, extend signaling of a number of spatial streams, and/or extend a number of EHT-SIG symbols.

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 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： An access point station (AP) communicates with a plurality of non-AP stations (STAs) within a synchronized transmission opportunity (S-TXOP). The S-TXOP may comprise an S-TXOP trigger followed by a plurality of S-TXOP slots. After transmission of the S-TXOP trigger, the AP may encode, for transmission within an S-TXOP slot, a downlink (DL) multi-user physical layer protocol data unit (DL MU-PPDU). The DL MU-PPDU may include a preamble followed by a data field. To indicate that a previously signaled resource unit (RU) allocation is to be used during the S-TXOP slot, the AP may encode the preamble to include an allocation ID of the previously signaled RU allocation in a signal field (SIG) of the preamble and to include a SIG-2 presence indicator to indicate that a second signal field (SIG-2) is not included in the preamble.

The device may connect a first AP of the AP MLD to a first station device (STA) of the non-AP MLD using a first link. The device may connect a second AP of the AP MLD to a second STA of the non-AP MLD using a second link. The device may use a link bitmap field included in a frame, wherein the link bitmap field comprises a first bit associated with the first STA and a second bit associated with the second STA. The device may communicate with the non-AP MLD based on the link bitmap.
