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 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 access point (AP) station (STA) configured for operating in a next-generation (NG) wireless local area network (WLAN) (i.e., EHT) are generally described herein. In some embodiments, a comb resource unit (RU) structure may be used to distribute tones of an RU across a wider bandwidth for narrow RU power spectral density (PSD) boosting for longer-range transmission in EHT to meet ETSI and/or FCC limitations.

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： Embodiments of a station (STA) and method of communication are generally described herein. The STA may be included in a first plurality of STAs affiliated with a first multi-link logical entity (MLLE). A plurality of links may be established between the first MLLE and a second MLLE, wherein the second MLLE may be affiliated with a second plurality of STAs. The STA may receive a first subset of a sequence of MAC protocol data units (MPDUs). A second subset of the sequence of MPDUs may be transmitted by another STA of the first plurality of STAs. The STA may transmit a block acknowledgement (BA) frame that includes: a number of BA bitmaps, configurable to values greater than or equal to one; and BA control information for each of the BA bitmaps.

摘要： Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. An AP may be configurable to operate as a master AP of a multi-AP group comprising the master AP and one or more satellite APs. The master AP may select, from the multi-AP group, a set of APs that is to communicate with a STA in accordance with joint processing. The master AP may allocate one or more spatial streams to each of the APs of the set of APs for a joint transmission of a null data packet (NDP) to the STA for channel sounding. The master AP may transmit an NDP announcement (NDPA) that indicates that the APs of the set of APs are to perform the joint transmission of the NDP.

摘要： Embodiments of an access point (AP), station (STA), and method of communication are generally described herein. The AP may perform channel sensing in a first channel of a first frequency band and a second channel of a second frequency band to obtain access for transmission of a physical layer convergence procedure (PLCP) protocol data unit (PPDU) that comprises multiple subframes. The transmission of the PPDU may be configurable to use a multi-band layer-1 aggregation of the first and second channels. While the second channel is unavailable, the AP may transmit one or more subframes on the first channel without usage of the multi-band layer-1 aggregation. When it is determined that the second channel has become available, the AP may switch to synchronized transmission of the subframes on the first and second channels in accordance with the multi-band layer-1 aggregation.

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.
