摘要： This disclosure describes systems, methods, and devices related to ultra-low latency (ULL). A device may generate a first frame to be sent on a first link in a multi-link operation (MLO) with an multi-link device (MLD). The device may generate a second frame to be sent on a second link in the MLO with the MLD. The device may divide the first frame and the second frame into a first plurality of segments and a second plurality of segments separated by one or more first and second time gaps, respectively. The device may indicate to a first station device having a ULL packet to initiate a transmission of the ULL packet during an earliest time gap on the first link. The device may cause to send the one or more first and second plurality of segments on the first link and second link respectively.

摘要： Methods, apparatuses, and computer readable media for ultra-low latency out-of-band radios are disclosed. Apparatuses of a station (STA) are disclosed, where the apparatuses comprise processing circuitry configured to associate with an access point (AP) on a first channel using a first transmit power, encode a physical (PHY) protocol data unit (PPDU) for transmission on a second channel, and configure the STA to transmit the PPDU on the second channel with a second transmit power, wherein a bandwidth of the first channel is less than the bandwidth of the second channel and wherein the first transmit power is greater than the second transmit power. The second channel may be punctured based on overlapping basic service sets (BSS) (OBSSs) signal strengths. The use of the second channel is restricted for communications related to low-latency applications. The transmit power on the second channel is reduced to lower the interference with OBSSs.

摘要： This disclosure describes systems, methods, and devices related to fast transition Wi-Fi roaming operations. A device may generate, during a first association of the device to a first access point, a request to authenticate the device to a second access point; send, during the first association, the request to authenticate; receive, during the first association, a response indicating that the device is authenticated to the second access point; generate, during the first association, a reassociation request to the second access point; determine that a time between sending the request to authenticate and generating the reassociation request is less than a threshold time; send, based on the determination that the time is less than the threshold time, the reassociation request to the second access point; and receive a reassociation response indicative of a second association of the device to the second access point.

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： Embodiments of an Extremely High Throughput Station (EHT STA) (STA1) configured for operating in a next-generation (NG) wireless local area network (WLAN) are described herein. In some embodiments, the EHT STA encodes a common signal field (SIG) (Coex-SIG) of an EHT PPDU to include a TXOP duration field. The TXOP duration field is more than seven bits to indicate an actual TXOP duration of a transmission from the EHT STA comprising the EHT PPDU transmitted to a second station (STA2). Decoding the TXOP duration field of the EHT PPDU by a third-party station (STA4) causes the third-party station (STA4) to defer a transmission until after an end of the transmission from the second station (STA2).

摘要： This disclosure describes systems, methods, and devices related to multi-link traffic steering. A device may establish one or more links with a station multi-link device (STA MLD), wherein the STA MLD comprises one or more logical entities defining separate station devices. The device may generate a traffic indication map (TIM) bitmap of a plurality of bits, wherein one or more bits are associated with an association identification (AID) corresponding to the STA MLD. The device may set the one or more bits to a first value to indicate that there is data to be retrieved by the STA MLD on any of the one or more links. The device may generate one or more beacon frames each comprising a same TIM element, wherein the TIM element comprises the TIM bitmap. The device may cause to send one or more beacon frames on each of the one or more links.

摘要： Embodiments provide a device profile mechanism for wireless devices. Many embodiments comprise a medium access control (MAC) sublayer logic to build frames comprising a device profile index element for a first device. Embodiments may facilitate access by a second device to a device profile for the first device without communication of the entire device profile from the first device. In some embodiments, the second device may access a storage medium integrated with or accessible to the second device to determine the device profile. Some embodiments may store the device profile index element in memory, in logic, or in another manner that facilitates transmission of the device profile index element in frames. Some embodiments may receive and detect communications with the device profile index element. Further embodiments may generate and transmit a communication with the device profile index element.

摘要： Embodiments may define traffic priorities to facilitate transmissions for wireless communications devices. Many embodiments comprise MAC sublayer logic to generate and transmit management frames such as beacon frames, association response frames, reassociation response frames, and probe response frames with an access category for low power consumption stations or sensor stations comprising a parameter record defining a contention window that is the earliest contention window to open amongst contention windows defined for the access categories for traffic. In some embodiments, the MAC sublayer logic may store the parameter record sets for access categories in memory, in logic, or in another manner that facilitates transmission of the frames. Some embodiments may receive and detect communications with frames comprising the access categories and store a parameter set for one or more of the access categories in a management information base.

摘要： A wireless communication device comprises a transceiver configured to communicate information with one or more neighbor devices in accordance with a sync mode of a WiFi communication protocol, and a controller. The controller is configured to monitor for reception of at least one of a response frame or a beacon frame sent by any neighbor device, determine whether to schedule transmission of a service frame, and change operation to a background scan mode when the at least one of the response frame or the beacon frame sent by any neighbor device is undetected for a specified time duration and the transmission of a service frame is unscheduled.
