摘要: This disclosure describes systems, methods, and devices related to enhanced bandwidth selection for wireless devices. A device may generate a request frame with at least one of a first indication of a bandwidth for which a second device is to measure a first noise level or a second indication of a resource unit for which the second device is to measure a second noise level. The device may send the request frame to the second device. The device may identify a response frame received from the second device, the response frame having a third indication of the first noise level or the second noise level and a fourth indication of the bandwidth or the resource unit. The device may determine, based on the first noise level or the second noise level, a parameter associated with a subsequent frame to send to the second device.

摘要: This disclosure describes systems, methods, and devices related to security for multi-link operations. A multi-link device (MLD) may establish a first communication link between a first device of the MLD and a first device of a second MLD, and a second communication link between a second device of the MLD and a second device of the second MLD. The MLD may generate a group-addressed message. The MLD may protect the group-addressed message using a first key or a first integrity key. The MLD may protect the group-addressed message using a second key or a second integrity key. The MLD may send, using the first communication link, the group-addressed message protected using the first key or the first integrity key, and may send, using the second communication link, the group-addressed message protected using the second key or the second integrity key.

摘要: This disclosure describes systems, methods, and devices related to multi-link operation. A device may configure a single N×N transmit (TX)/receive (RX) radio to a plurality of 1×1 TX/RX radios, where N is a positive integer. The device may monitor a first channel of a plurality of channels to determine its availability. The device may monitor a second channel of the plurality of channels to determine its availability. The device may identify a first control frame received from an access point (AP) multi-link device (MLD) on the second channel. The device may cause to send a second control frame to the AP MLD on the second channel. The device may configure back to a single N×N TX/RX radio to receive a data frame.

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.

摘要: To communicate with a plurality of non-AP stations (STAs) within synchronized transmission opportunities (S-TXOPs), an access point station (AP) performs an initial management frame exchange with the STAs. During the initial management frame exchange, one or more sets of semi-static allocation parameters are signalling to the STAs. Each set of semi-static allocation parameters is associated with an allocation index (IDx). The AP may communicate data with the STAs during S-TXOPs that follow the initial management frame exchange. Each of the S-TXOPs may include an S-TXOP trigger. The S-TXOP trigger may be encoded to include one of the allocation indices to indicate a known allocation for use during the associated S-TXOP when a set of the predetermined semi-static allocation parameters are to be used. The S-TXOP trigger may be encoded to include full allocation information to indicate a new allocation for use during the associated S-TXOP when the predetermined semi-static allocation parameters are not used.

摘要: This disclosure describes systems, methods, and devices related to group-addressed transmissions in wireless communications. A device may determine a first time associated with a first multicast transmission including a first basic service set (BSS) identifier (BSSID) associated with a first BSS of a multi-BSSID set including the first BSS and a second BSS. The device may send a frame including the first time, the first BSSID, wherein the frame indicates that the second BSS may ignore multicast transmissions at the first time, and wherein the first time is during a beacon interval associated with a beacon addressed to the multi-BSSID set. The device may send the first multicast transmission at the first time and may send a second multicast transmission at a second time, wherein the second time is during the beacon interval, and wherein the second multicast transmission includes a second BSSID associated with the second BSS.

摘要: This disclosure describes systems, methods, and devices related to scheduling asynchronous transmissions by other access point (AP) devices in a multi-AP environment. A method may include a coordinating AP identifying a first time for a first coordinated AP device to send a first physical layer (PHY) protocol data unit (PPDU) using a first frequency segment; identifying a second time different than the first time for a second coordinated device to send a second PPDU using a second frequency segment; generating one or more frames comprising indications that the first AP device is to send the first PPDU using the first frequency segment and that the second AP device is to send the second PPUD using the second frequency segment; and causing to send the one or more frames to the first coordinated AP device and the second coordinated AP device.

摘要: Embodiments of a high efficiency (HE) access point (HE AP) and HE station (HE STA) are generally described herein. The HE AP may transmit a frame that includes a transmit power envelope element to indicate local maximum transmit power constraints for an operating bandwidth of the HE AP on a per-segment basis. The operating bandwidth may be configurable for division into segments of a configurable segment size. The transmit power envelope element may include: a transmit power information field that includes: a local maximum transmit power count subfield that indicates the operating bandwidth, and a segment size subfield that indicates the segment size; and for each of the segments, a local maximum transmit power per segment field that indicates a local maximum transmit power for the segment.
