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 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.

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 a station (STA), access point (AP) and method for determination of transmit power for spatial reuse are generally described herein. The STA may detect, in the channel, an overlapping basic service set (OBSS) physical layer convergence procedure protocol data unit (PPDU) from an OBSS AP. The STA may determine, based at least partly on an ESS color parameter included in the OBSS PPDU, whether the OBSS AP is included in the ESS network. The STA may determine an OBSS power threshold based at least partly on whether the OBSS AP is included in the ESS network. The STA may determine, based at least partly on a comparison between the OBSS power threshold and a received power of the OBSS PPDU, whether to transmit an uplink PPDU to the BSS AP in the channel during the TXOP.

摘要： Methods, apparatuses, computer readable media for spatial reuse for uplink multi-user transmissions. An apparatus of a station comprising processing circuitry is disclosed. The processing circuitry may be configured to decode a first portion of a physical layer convergence procedure (PLCP) protocol data unit (PPDU), and configure the station to transmit a frame, if the PPDU is an overlapping basic service set (OBSS) PPDU, and a receive power of the PPDU is below an overlapping power detect level. An apparatus of an access point comprising processing circuitry is disclosed. The processing circuitry may be configured to encode a PPDU comprising a basic service set identifier of the access point, and encode the PPDU to indicate spatial reuse (SR) delay, SR restricted, or SR not permitted. The processing circuitry may be further configured to configure the access point to transmit the PPDU.

摘要： An access point (AP) station (STA) (AP STA) that is part of an AP multi-link device (MLD) may be configured as a reporting AP may encode a BSS Transition Management (BTM) request frame for transmission to one or more associated non-AP stations (STAs). The BTM request frame may include a neighbor report element encoded to include information about one or more neighbor APs. The neighbor report element may indicate whether the one or more neighbor APs identified in the neighbor report element are part of an AP MLD and, when a neighbor AP is indicated to be part of an AP MLD whether the reporting AP is part of the indicated AP MLD. The AP STA may decode a reassociation frame from one of the non-AP STAs for transition from one of the AP STAs of the AP MLD to one of the neighbor APs.

摘要： This disclosure describes systems, methods, and devices related to traffic indications for multi-link devices (MLDs). A device may generate a first traffic indication map (TIM) with a first bitmap including a first indication that traffic is to be sent by a first access point (AP) device of the MLD to a first non-AP device of a second MLD using a first communication link. The device may generate a second TIM with a second bitmap including a second indication that no traffic is to be sent by a second AP device of the MLD to a second non-AP device of the second MLD using a second communication link. The device may send, using the first communication link, the beacon, the beacon including the first TIM and the second TIM. The device may send, using the first communication link, a data frame to the first non-AP device of the second MLD.

摘要： Systems, methods, and devices related to an EHT multi-AP group are described. The coordinated APs of the EHT group are synchronized to the coordinator AP using a periodic or non-periodic frame. Each coordinated AP then synchronizes STAs associated with the coordinated AP. In response to an MPDU, either triggered by a trigger frame from the coordinator AP or initiated by the STA, an ACK frame or NDP response is sent by each AP receiving the MPDU. The response to the MPDU is dependent on whether frame aggregation is used, as well as whether the trigger frame triggers transmission of MPDUs from multiple STAs.
