    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 methods, devices and systems for wireless communication, and particularly, methods, devices and systems for including signaling regarding enhanced features of new wireless communication protocols. The signaling may be included in various portions of a physical layer preamble of a wireless transmission. In some implementations, the physical layer preamble may be used to indicate puncturing of subbands or content channels that may carry further signaling in accordance with preamble signaling designs of this disclosure. The physical layer preamble signaling be parallelized for different subchannels of a wireless channel that consists of multiple subchannels. Some implementations of the physical layer preambles may be used to multiplex different types of wireless local area network communications into different subsets of the plurality of subchannels of the wireless channel.

    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for group formation and sounding for distributed multi-user multiple input multiple output (MU-MIMO). Some implementations include a method of wireless communication. The method includes transmitting, from a first access point of a plurality of access points, an announcement frame for performing a beamforming procedure for a distributed transmission. The distributed transmission includes a transmission from the plurality of access points. The announcement frame includes at least one identifier of a user terminal in a different basic service set than a basic service set of the first access point. The method further includes transmitting a packet for measuring a channel. The method further includes receiving feedback information from the user terminal based on the packet for measuring the channel. The method further includes transmitting the distributed transmission using the beamforming procedure.

    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).

    IPC: H04W72/04

    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.
