Abstract: Methods, systems, and devices for wireless communications are described for control signaling in next generation wireless local area network (WLAN) environments. A message transmitted by an access point may allocate resources to a plurality of stations. The access point may be configured to allocate up to 320 MHz of total bandwidth along with coarse punctures. The access point may also allocate up to eight space-time streams to each station in a multi-user multiple-input multiple output (MU-MIMO) transmission, and support simultaneous transmission to up to sixteen stations. To support 320 MHz bandwidth and up to sixteen stations, one or more signaling fields used in other environments may be repurposed to effectively signal the additional resources available in a next generation WLAN.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for multiplexing clients of different generations in trigger-based transmissions, including trigger-based transmissions in extremely-high throughput (EHT) Wi-Fi systems. An access point (AP) may generate a trigger frame compatible with two types of stations (STAs), such as EHT STAs and legacy (or high efficiency (HE)) STAs. The AP may transmit the trigger frame to a group of STAs, where legacy STAs may process the trigger frame a legacy trigger frame. EHT STAs may process the trigger frame to determine resource unit (RU) allocations for uplink transmissions in a bandwidth greater than a legacy bandwidth. An EHT STA may determine the resources in the larger bandwidth based on an EHT RU allocation table, a legacy RU allocation table and an additional bit in the trigger frame, or an ordering of RU allocations in the trigger frame.

Abstract: This disclosure provides systems, methods, and apparatuses for associating a wireless communication device such as a wireless station (STA) of a STA multi-link device (MLD) with an access point (AP) MLD that includes a first AP associated with a first communication link of the AP MLD and includes one or more secondary APs associated with one or more respective secondary communication links of the first AP MLD. The AP MLD transmits a frame including an advertising information element carrying discovery information for the first AP of the AP MLD, including a first portion carrying discovery information for each secondary AP of the one or more secondary APs of the AP MLD, and including a second portion carrying common attributes of the one or more secondary APs of the AP MLD.

Abstract: Methods and apparatuses are disclosed for communicating over a wireless communication network. One such apparatus can include a memory that stores instructions and a processor coupled with the memory. The processor and the memory can be configured to identify a transmission mode for a transmission of a signal; select a tone plan for transmission of the signal within a 320 MHz total channel bandwidth or a 240 MHz total channel bandwidth, where the tone plan includes a 256 point tone plan, 512 point tone plan, 1024 point tone plane, 2048 point tone plan, 4096 point tone plan, or some combination thereof, and where the tone plan is selected based at least in part on the transmission mode; generate the signal according to the tone plan; and transmit the signal over the 320 MHz total channel bandwidth or over the 240 MHz total channel bandwidth.

Abstract: This disclosure provides methods, devices, and systems for wireless communications. In some systems, an access point (AP) may assign a resource unit (RU) including a non-contiguous set of tones of a channel to a wireless node, such as a station (STA). The non-contiguous set of tones includes at least some tones that are non-contiguous in the frequency domain with all other tones of the set. The AP may generate an indicator for this RU and may transmit the indicator to the wireless node. The wireless node may receive the indicator, determine the non-contiguous set of tones for the indicated RU, and transmit data over the non-contiguous set of tones for the RU. The AP may receive the data via the RU (over the non-contiguous set of tones).

Abstract: An access point (AP) may signal management frames that include two operation information fields indicating two channel widths for different classes of wireless stations (STAs). STAs may identify one of the two operation information fields based on capabilities of the STA (e.g., whether or not the STA is capable of dual band channel bonding, resource unit or physical channel puncturing, etc.). In some cases, one operation information field may indicate a channel width within a first and second frequency band (e.g., within the 5 GHz band and the 6 GHz band), as well as a puncturing scheme associated with the channel width. In some cases, the operation information field may indicate a dual band channel bonding configuration, where two frequency segments associated with the channel bonding configuration are in two different frequency bands. In some cases, a tightened spectral mask may be used for such dual band channel bonding configurations.

Abstract: Various aspects of the disclosure relate to communication using a data unit that includes at least one mid-amble. In some aspects, an apparatus may use mid-ambles for mobility scenarios (e.g., when the apparatus is moving outdoors). The disclosure relates in some aspects to signaling associated with the use of mid-ambles. In some aspects, an apparatus may signal whether it supports sending and/or receiving data with mid-ambles. In some aspects, an apparatus may signal whether a particular data unit includes at least one mid-amble. In some aspects, an apparatus may signal an indication of at least one mid-amble update interval. In some aspects, an apparatus may signal whether a mid-amble includes a short training field.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for partial bandwidth feedback based on punctured sounding. Punctured sounding is used by a transmitting device that omits portions of a channel bandwidth based on a puncturing pattern. The puncturing pattern may be based on an exclusion bandwidth zone to avoid transmissions on portions of channels that may interfere with an incumbent system transmission. The puncturing pattern may be indicated in a null data packet announcement (NDPA) to inform the receiving device that a subsequent NDP will be punctured. The receiving device may determine the feedback by measuring the portions of the NDP that are not punctured. Beamforming may be enhanced by using punctured sounding between two beamforming endpoints.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for multiplexing clients in a wireless communication network. In one aspect, a wireless station (STA) receives a preamble including a first wireless local area network (WLAN) signaling field from an access point (AP). The first WLAN signaling field includes first and second indications of first and second channel bandwidths. The first channel bandwidth includes a first set of subchannels and used by the AP to communicate with a first set of stations. The second channel bandwidth may include the first set of subchannels and a second set of subchannels and used by the AP to communicate with a second set of stations. The STA may identify a location of at least one second WLAN signaling field for the STA based on the first and second indications of the first and second channel bandwidths.
