摘要： This disclosure describes methods, apparatus, and systems related to network allocation vectors. A device is disclosed that may determine a first length of time corresponding to a first spatial reuse transmit opportunity (SR-TxOP) time period. The device may determine a second length of time corresponding to a transmit opportunity (TxOP) time period that starts when a request to send (RTS) frame is transmitted and ends after the first length of time ends. The device may cause to transmit the RTS frame, over the channel, to a first device. The device may determine that a clear to send (CTS) frame is received from the first device, the CTS frame comprising a first duration field equal to having a third length of time corresponding to a second transmission opportunity (SR-TxOP). The device may determine that the third length of time corresponds to a length of time between when the CTS frame was transmitted and when the first length of time ends. The device may determine that the third length of time is less than the second length of time. The device may cause to transmit a CTS to self frame, over the channel, comprising a second duration field equal to having a fourth length of time, wherein the fourth length of time correspond to a length of time between when the CTS to self frame is transmitted and when the first length of time ends.

摘要： Embodiments of an access point (AP), station (STA) and method for channel access are generally described herein. The AP may contend for access to a channel. The contention may be performed in accordance with an omni-directional enhanced distributed channel access function (EDCAF) for transmission within an omni-directional pattern. The contention may be further performed in accordance with a directional EDCAF for transmission to a station (STA) in a directional pattern. The AP may determine whether to transmit within the omni-directional pattern based at least partly on an omni-directional backoff parameter. The AP may further determine whether to transmit in the directional pattern based at least partly on a directional backoff parameter.

摘要： A Quality-of-Service (QoS) Management AP is configured to support QoS Management features and to perform a QoS Management Protocol. The AP decodes an Enhanced Add Traffic Stream (E-ADDTS) Request QoS Action Frame (E-ADDTS Req) received from a station (STA) to initiate QoS setup for a traffic stream. The STA may be a QoS Management STA configured to support the QoS Management features and perform the QoS Management protocol. The AP may encode, for transmission to the STA in response to the E-ADDTS Req, an E-ADDTS Response QoS Action Frame (E-ADDTS Resp) which includes a status code to indicate whether the QoS setup has been accepted. When the QoS setup is accepted, the E-ADDTS Resp includes a QoS setup ID within a QoS setup ID field in the E-ADDTS Resp that uniquely identifies the QoS setup for the traffic stream.

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： 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.

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 link aggregation between devices. A device may determine a first frequency band and a second frequency band for sending data to a second device in a multiband link aggregation session. The device may cause to send, in an initial state, a setup request frame to the second device for establishing the multiband link aggregation session. The device may receive, in a setup completion state, a setup response frame from the second device to establish the multiband link aggregation session. The device may cause to send, in an operating mode established state, the data to the second device over the first frequency band and/or the second frequency band in the multiband link aggregation session.

摘要： Embodiments of an access point (AP), station (STA) and method for link aggregation are generally described herein. An aggregated link for multiple channels may be established. The link may be aggregated at an upper medium access control (MAC) entity, which may communicate with multiple lower MAC entities for the channels. The upper MAC entity may assign packet numbers (PNs) to a sequence of MAC service data units (MSDUs) for the aggregated link and may allocate the MSDUs to the channels. The PNs may enable reordering at a receiving entity. The lower MAC entities may assign sequence numbers (SNs) to MAC protocol data units (MPDUs). The SNs may enable acknowledgement at a receiving entity. The MPDUs may include the SNs and the corresponding PNs.

摘要： Embodiments of a station (STA) and method for communication on primary and secondary channel resources are generally described herein. The STA may transmit a grant frame to indicate a transmission of a data payload by the STA during a grant period. The grant frame may indicate whether the data payload is to be transmitted on primary channel resources or on secondary channel resources. The STA may transmit the data payload to a destination STA on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources. The grant frame may be transmitted on the primary channel resources and on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources.

摘要翻译： 这里一般地描述用于主信道资源和辅信道资源上的通信的站（STA）和方法的实施例。 STA可以在授权周期期间发送授权帧以指示STA发送数据有效负载。 授权帧可以指示数据有效载荷是要在主信道资源还是在次信道资源上发送。 当授权帧指示要在次要信道资源上发送数据有效载荷时，STA可以在辅助信道资源上向目标STA发送数据有效载荷。 当授权帧指示要在辅助信道资源上发送数据有效载荷时，授权帧可以在主信道资源和次信道资源上发送。
