    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: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, the apparatus may determine whether to transmit a frame with CSDs based on a number of antennas, a number of streams, or both. In another aspect, the apparatus may determine a first set of CSD values for transmitting a first set of information associated with a first portion of the frame. In a further aspect, the apparatus may determine a second set of CSD values for transmitting a second set of information associated with a second portion of the frame. In yet another aspect, the apparatus may transmit the first set of information based on the first set of CSD values and the second set of information based on the second set of CSD values using the number of antennas, the number of streams, or both.

    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: 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.

    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.
