摘要: This disclosure describes systems, methods, and devices related to multi-user uplink channel sounding. A device may determine a channel sounding sequence with one or more access points (APs), wherein the channel sounding sequence comprises a null data packet announcement (NDPA) communicated with at least one of the one or more APs. The device may determine a first group of station devices (STAs) associated with a first basic service set (BSS). The device may cause to send a trigger frame to the first group of STAs to solicit an uplink NDP from each STA of the first group of STAs. The device may identify a first uplink NDP received from a first STA of the first group of STAs. The device may identify a second uplink NDP received from a second STA of a second group of STAs.

摘要: Methods, apparatuses, and computer readable media for a common preamble for wireless local-area networks (WLANs). An apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to encode an AP trigger frame that includes a resource allocation for other APs to transmit trigger frames to perform an uplink or downlink multi-user transmission with stations (STAs). The resource allocation includes information so that the transmissions are coordinated at the physical level to lessen interference among the APs and the stations. The processing is configured to encode a trigger frame for multi-AP request-to-send (RTS), the multi-AP trigger frame comprising for each of a plurality of APs, the trigger frame indicating that each of a plurality of APs are to transmit a physical (PHY) protocol data unit (PPDU) comprising a request-to-send (RTS) or multi-user (MU) RTS (MU-RTS).

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. The AP may be configurable to operate as a master AP of a multi-AP group. The master AP may establish the multi-AP group by: transmitting one or more messages to advertise the multi-AP group; and exchanging signaling with one or more of the other APs of the multi-AP group. The signaling may include at least one message related to one of the other APs joining the multi-AP group. The master AP may establish the multi-AP group to enable usage of AP Trigger Frames (AP TFs) for coordination of resources to be used for downlink transmissions of the APs of the multi-AP group.

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: 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 (AP) station (STA) (AP STA) may be configured to operate as a multi-AP controller in a multi-AP network. A multi-AP group formation message is encoded for transmission to other APs in the multi-AP network. The multi-AP group formation message is encoded to notify the APs of the formation of an extremely-high throughput (EHT) multi-AP group, to designate whether an AP is a member of an EHT multi-AP group, and whether an AP can take the role of a coordinator AP or coordinated AP within the EHT multi-AP group. For multi-AP joint processing, the AP STA is further configured to encode an AP trigger frame for transmission to the APs in the multi-AP network. The AP trigger frame is to trigger physical layer (PHY) and medium-access control layer (MAC) parameter synchronization. The AP trigger frame is to trigger transmission of aggregated MAC protocol data units (A-MPDUs) by the APs that include MAC parameters and PHY parameters.

摘要: This disclosure describes systems, methods, and devices related to allocating non-continuous resource units (RUs). A device may determine a non-continuous RU allocation for one or more devices in a 80 MHz bandwidth including four 20 MHz channels, the non-continuous RU allocation including disabled tones of a 20 MHz channel of the four 20 MHz channels, and the disabled tones being a subset of tones within the 20 MHz channel. The device may determine a high efficiency wireless frame comprising an indication of the non-continuous RU allocation. The device may send the high efficiency wireless frame to one or more multiple devices.
