  • Publication number: 20190288895
    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for communicating over a wireless communication network. A wireless communication device may be configured to generate and transmit a message according to a tone plan for transmission to multiple destination devices within one of a 240 or 320 MHz channel bandwidth. The message may include a short training field (STF) and a long training field (LTF). The STF may be used by a receiver to adjust an automatic gain control (AGC) function. The LTF may be used for channel estimation. In some implementations, the STF may have a data tone plan formed from a concatenated sequence of sub-STFs. A phase rotation applied to at least one of the sub-STFs of the concatenated sequence may reduce a peak-to-average-power ratio (PAPR) of the message as compared to a non-phase rotated concatenated sequence of sub-STFs.

  • Publication number: 20190261369
    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.

  • Patent number: 10375683
    Abstract: The present disclosure provides various aspects related to techniques for generating trigger frames, at an access point (AP), that reduce the overhead associated with triggering an uplink transmission from the wireless station (STA). Features of the present disclosure achieve this by, for example, utilizing a single per-user information field of the trigger to signal a plurality of random access resource units that may be allocated to the one or more STAs in the network. Such a technique is an improvement over the conventional system that require each random access resource unit to be signaled separately in a separate per-user information field (thus increasing the overhead). Additionally, aspects of the present disclosure allow the AP to effectively signal to the STA whether the one or more resources allocated to the at least one STA are a single user resource unit allocation or a multi-user resource unit allocation.

  • Patent number: 10356777
    Abstract: Method and systems are disclosed for qualifying a wireless device as frequency hopping device. In some aspects, an access point (AP) may determine a frequency hopping pattern for the wireless device, and then allocate a sequence of unique resource units to the wireless device based on the frequency hopping pattern. Each of the unique resource units include a different set of frequency subcarriers. The AP may receive a series of uplink orthogonal frequency-division multiple access (OFDMA) transmissions from the wireless device on the allocated sequence of unique resource units.

  • Publication number: 20190199491
    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for wireless communication with partial channel puncturing. Using partial channel puncturing, a wireless local area network (WLAN) device may modulate data on a first portion of a wireless channel while refraining from modulating data on a second portion of the wireless channel. The partial channel puncturing can be used with an exclusion bandwidth zone defined for the WLAN. The exclusion bandwidth zone prevents transmissions on portions of channels so that the WLAN transmissions do not interfere with an incumbent system transmission in the exclusion bandwidth zone.

  • Publication number: 20190141717
    Abstract: Aspects of the present disclosure provide techniques for interleaving in single user (SU) preamble puncturing in wireless local area networks (WLANs). In one implementation, a wireless device can identify an SU preamble puncture transmission, encode information for the SU preamble puncture transmission to produce encoded bits, parse the encoded bits into multiple segments, parse the encoded bits among multiple resource units (RUs) within each of the multiple segments, and perform a tone interleaving of the encoded bits within each of the multiple RUs. These techniques can be used in a 6 GHz band, as well as a 2.4 GHz band or a 5 GHz band.

  • Publication number: 20190141570
    Abstract: The present disclosure provides techniques for preamble puncturing in wireless local area networks (WLANs). In one implementation, an access point (AP) can identify, within a channel width, one or more bandwidth regions associated with incumbent technologies. The AP can broadcast or advertise, to a basic service set (BSS) initiated or started by the AP, a preamble puncture pattern in one or more management frames, the preamble puncture pattern being based on the bandwidth regions associated with incumbent technologies. In another implementation, an AP can identify a single user (SU) preamble puncture transmission, and can signal in a common portion of a SIG-B field of a multi-user (MU) PPDU format that a resource unit (RU) size is assigned to a same user to indicate the SU preamble puncture transmission. Although these techniques may be used in any frequency band, typical frequency bands may include, but are not limited to, a 2.4 GHz band, a 5 GHz band, and/or a 6 GHz band.
