摘要： Embodiments of a station (STA), access point (AP) and method for communication in the presence of spatial reuse (SR) transmissions are generally described herein. An STA may determine a received signal strength indicator (RSSI) based on one or more inbound physical layer convergence procedure (PLCP) protocol data units (PPDUs) received from a destination STA. The STA may determine, based at least partly on a comparison between the RSSI and a predetermined threshold, whether SR transmissions by other STAs in the channel are permissible. The SR transmissions may be concurrent to transmissions by the STA within the TXOP in the channel. The STA may transmit a PPDU to the destination STA that includes an SR indicator that indicates whether the SR transmissions are permissible.

摘要： Apparatus, computer readable media, and methods are disclosed for sending feedback in a high efficiency service field. An apparatus is disclosed comprising processing circuitry configured to: decode a trigger frame from a second wireless device, wherein the trigger frame indicates a resource allocation for an uplink (UL) multi-user (MU) transmission for the first wireless device. The processing circuitry may be further configured to: determine feedback for a second wireless device based on the resource allocation. The processing circuitry may be further configured to: encode a physical layer convergence protocol (PLCP) protocol data unit (PPDU) to include a high-efficiency (HE) service field comprising the feedback in a physical (PHY) portion of the PPDU. And, the processing circuitry may be further configured to: configure the first wireless device to transmit the PPDU in accordance with the resource allocation to the second wireless device.

摘要： Methods, apparatuses, computer readable media for basic service set (BSS) identification (ID). An apparatus of a station comprising processing circuitry is disclosed. The processing circuitry is configured to: decode a first frame comprising a first receiver address and a first transmitter address. The processing circuitry may be further configured to classify the first frame as an inter-BSS (inter-BSS) frame or an intra-BSS frame and decode a second frame comprising a second receiver address. The processing circuitry may be further configured to classify the second frame as the inter-BSS frame, if the second receiver address matches the first transmitter address and the first frame is classified as the inter-BSS frame. The processing circuitry may be further configured to classify the second frame as the intra-BSS frame, if the second receiver address matches the first transmitter address and the first frame is classified as the intra-BSS frame.

摘要： Methods and devices are described for providing wireless stations (STAs) with two sets of enhanced distributed channel access (EDCA) parameters. Legacy EDCA parameters that are for single user (SU) operations and may be used by both high-efficiency (HE) STAs and legacy STAs without multi-user (MU) capability. MU EDCA parameters are defined to be more restrictive than legacy EDCA parameters in favoring MU operations. Embodiments are described that define sets of rules for regulating how STAs capable of both SU and MU uplink operations can use the different sets of EDCA parameters.

摘要： An access point (AP) multi-link device (MLD) (AP MLD) comprises a plurality of affiliated access points (APs) including a first affiliated AP (AP1) and a second affiliated AP (AP2). When the first affiliated AP (AP1) is configured to operate as a reporting AP, the reporting AP may encode MLD information in a management frame for transmission to one or more STAs of a station MLD (STA MLD). The MLD information may include a basic service set (BSS) identifier (ID) (BSSID) of the AP1 and may include a BSSID index of at least the AP2 when the AP2 is in a multiple BSSID (MBSSID) set that does not include the BSSID of the AP1. The MLD information may further include at least one of a delivery traffic indication map (DTIM) period of the AP2. The AP1 may decode a frame from a non-AP STA of the STA MLD that includes a BSSID of the MBSSID set for association or reassociation.

摘要： For example, a reporting wireless communication station (STA) of a Multi-Link Device (MLD) including a plurality of STAs may be configured to generate a multi-link element including one or more STA profile subelements for one or more reported STAs of the MLD, respectively, wherein a STA profile subelement corresponding to a reported STA includes one or more elements of information corresponding to the reported STA; to set a field in the STA profile subelement corresponding to the reported STA to indicate whether or not the STA profile subelement corresponding to the reported STA is to be interpreted to provide all information corresponding to the reported STA; and to transmit a frame including the multi-link element.

摘要： This disclosure describes systems, methods, and devices related to multi-link power save indication. A device may establish two or more links with a non-access point (AP) multi-link device (MLD). 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.

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： 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.
