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 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： 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： This disclosure describes systems, methods, and devices related to multi-link acknowledgments. A device may transmit a trigger frame to a station device (STA) multi-link device (MLD), wherein the trigger frame polls the STA MLD to announce presence on communication links. The device may identify a null data packet (NDP) from the STA MLD announcing its presence on a set of communication links. The device may establish the set of communication links with the STA MLD, wherein the STA MLD comprises a plurality of station devices (STAs). The device may allocate a plurality of tone-sets to the plurality of STAs within the STA MLD. The device may identify energy on the allocated tone-sets for each link that the STA MLD has presence on.

摘要： An access point (AP) station (STA) configured for communicating with another STA within a synchronized transmission opportunity (S-TXOP) may encode an S-TXOP trigger for transmission at a beginning of the S-TXOP. The S-TXOP trigger may be followed by a plurality of slots within the S-TXOP. The S-TXOP trigger may include a synchronization information field, a station information list field and an optional schedule information field. The STA information list field may include an AID of each STA that is scheduled to communicate during the slots and an indication of whether semi-static configuration is enabled. When the S-TXOP trigger includes the optional schedule information field, it may include resource information for each slot which may include a slot identifier and a slot type indicator. The resource allocation for each slot further includes a scheduling information element when the semi-static configuration for the corresponding slot is not enabled.

摘要： This disclosure describes systems, methods, and devices related to multi-AP resource sharing. A device may participate in a set of coordinated access points (APs) for coordinating a sharing of one or more resources. The device may evaluate whether there is data to be transmitted to at least one associated station device. The device may, based on the evaluation, perform an action associated with acquiring a first transmit opportunity (TXOP) to be shared with one or more candidate APs of the set of coordinated APs.

摘要： This disclosure describes systems, methods, and devices related to channel access for multi-link devices (MLDs). A MLD may identify a first backoff count associated with a first enhanced distributed channel access function (EDCAF) for a first communication link used by the MLD; identify a second backoff count associated with a second EDCAF for a second communication link used by the MLD, the first backoff count less than the second backoff count; determine a time period after that the first backoff count reaches zero and during which to refrain from transmitting using the first communication link, the time period based on the second backoff count; determine that the first communication link transitioned from an idle state to a busy state during the time period; and generate a third backoff count associated with the first EDCAF based on the first communication link transitioning to the busy state during the time period.

摘要： Embodiments of a beacon interval with boundary time points (BTPs) to improve latency for time sensitive traffic (TST) in Extremely High Throughout (EHT) WLANS are disclosed herein. In some embodiments, a non-access point (AP) station (STA) is configured to decode a beacon frame received from an AP STA. The beacon frame may indicate one or more BTPs within a beacon interval (BI). The non-AP STA may obtain a transmission opportunity (TXOP) for a transmission to the AP STA. The TXOP may be bounded by the one or more BTPs. The non-AP STA may encode a PPDU for transmission to the AP STA during the TXOP.

摘要： Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may be configurable for multi-band operation in a plurality of frequency bands, each frequency band comprising one or more channels. The AP may select a subset of the frequency bands for which the AP is to request per-band channel availability information from the STA. The AP may transmit a Trigger Frame (TF) for a multi-band bandwidth query report polling (MB-BQRP) to request the per-band channel availability information. The AP may receive an uplink frame that includes a multi-band bandwidth query report (MB-BQR) that indicates the per-band channel availability information. The AP may determine, based on the MB-BQR, for an uplink transmission by the STA: one or more frequency bands of the subset of frequency bands, and one or more corresponding channels.
