  • Publication number: 20210385688
    Abstract: A wireless communication link is established between a first station (STA) and a second STA in a 6-GHz band. The first STA and the second STA the communicate in the 6-GHz band using a low-power indoor (LPI) long range (LR) physical-layer protocol data unit (PPDU). The LPI LR PPDU includes a legacy preamble, a universal signal field (U-SIG), an extreme-high-throughput signal field (EHT-SIG), an extreme-high-throughput short training field (EHT-STF), an extreme-high-throughput long training field (EHT-LTF), and a payload. Each of the legacy preamble, U-SIG and EHT-SIG is modulated and duplicated over multiple 20-MHz subchannels for a 80-MHz, 160-MHz or 320-MHz bandwidth over which the LPI LR PPDU is transmitted. Each of the EHT-STF, EHT-LTF and payload is modulated and transmitted on an entirety of the 80-MHz, 160-MHz or 320-MHz bandwidth.

  • Patent number: 11190986
    Abstract: Mechanisms of CCA status reporting and NAV distribution for coordinated transmissions in a multi-AP WLAN. A coordinator AP may broadcast a RTS frame to a set of coordinated APs, which allow the coordinated APs with a CCA clear status to set a protected period in a CST frame to silence the associated non-AP STAs. The coordinator AP also polls the coordinated APs to have them individually report their CCA statuses as well as additional information used for transmission coordination. In some embodiments, a status report from a coordinated AP may integrate the protected period setting and the CCA clean status indication, and therefore the coordinator AP just needs to poll for such a report without using RTS/CTS exchange. A coordinated AP may set a protected period to end at the complete transmission of a coordination frame. The coordination frame may specify the remaining TXOP duration information.

  • Publication number: 20210359724
    Abstract: Embodiments of the present invention provide an apparatus and method for a MAP wireless network that includes a collaborative channel sounding measurement phase to determine channel state information between devices (e.g., the channel state between an STA and a collaborative AP) for efficient configuration of the MAP wireless network and to improve the performance of the MAP wireless networks. The wireless AP and wireless STAs associated with the collaborative APs can simultaneously transmit by applying collaborative beamforming where the interferences between channels nullify each other (e.g., nulling), and the beamforming is performed based on a sounding phase performed by the collaborative APs. The sounding protocol can include a collaborative sounding measurement phase and a collaborative sounding feedback report phase, using Null Data Packets (NDPs), for example, as described herein according to embodiments of the present invention.

  • Patent number: 11159286
    Abstract: System and method of OFDMA transmission in which mid-ambles are configured on a per-user basis for channel variation adaptation. The multiple channels used in an OFDMA transmission may use different mid-amble settings based on their respective channel characteristics. Particularly, some channels may have mid-ambles and some may have not, and mid-amble update intervals may vary across the channels. For a trigger-based (TB) uplink (UL) OFDMA transmission, an AP may signal the per-user mid-amble information in the user information fields of the trigger frame. For a downlink (DL) OFDMA transmission, an AP may signal the per-user mid-amble information in the HE SIG-B fields.

  • Publication number: 20210314879
    Abstract: Embodiments of the present invention are drawn to methods and electronic devices capable of performing coordinate spatial reuse for wirelessly transmitting data on a channel in coordination with another wireless AP operating an overlapping BSS using the same wireless channel. The device can perform RSSI measurements and generate Per-RU RSSI reports including the RSSI measurements information for transmission to another wireless AP. The RSSI measurement can be performed by the device based on power levels detected when receiving TB PPDUs transmitted by wireless STAs responsive to trigger frames, for example. Based on the Per-RU RSSI report, a wireless AP can be configured to transmit data to an associated wireless STA without causing significant interference when another AP of the overlapping BSS is also transmitting, and can schedule frames for transmission from associated wireless STAs accordingly.

  • Patent number: 11134518
    Abstract: A cooperative multi-band wireless station architecture that enables full duplex operations of wireless stations (STAs). Such an STA includes a WIFI transceiver and one or more additional transceivers. The two transceivers (and the associated channels) operate in mutually exclusive WIFI bands or different types of protocols and therefore can transmit and/or receive simultaneously without signal interference to each other. The multiple transceivers can perform independent clear channel assessment (CCA) and then simultaneously perform signal transmission or reception jointly or independently. In a cooperative multi-band operation, one channel may be used as an independent assistant channel and responsible for supplying assistant information relevant to a transmission opportunity (TXOP) for the other channel (primary channel) to take corresponding actions.

  • Publication number: 20210281372
    Abstract: Systems and methods of transmitting a PPDU to or from a single user station (STA) in an OFDMA transmission by using multiple RUs. An access point (AP) allocates multiple RUs to an STA for an OFDMA transmission and correspondingly specifies the STA ID repeatedly in the user specific field of a SIG-B field in a downlink PPDU, or in the user information fields of a trigger frame. Alternatively, multiple AIDs of the STA can be specified in the user specific field or the user information fields instead of repeating the same STA ID. An indication may be inserted in the SIG-A field to indicate that the enhanced RU allocation scheme is used for the OFDMA transmission.

  • Publication number: 20210281382
    Abstract: A method pertaining to leftover bits processing for proportional round-robin resource unit (RU) parsing in extreme high-throughput (EHT) systems involves processing a stream of bits to provide processed bits. The method also involves transmitting the processed bits to a station (STA) over a combination of multiple resource units (RUs) assigned to the STA. In processing the stream of bits, the method may involve parsing the stream of bits to the combination of multiple RUs. Moreover, in an event of leftover bits remaining from the parsing, the method may further involve distributing the leftover bits to one or more RUs but not all RUs of the combination of multiple RUs.

  • Patent number: 11096132
    Abstract: A joint sounding mechanism used in a multi-AP system to gain channel information for joint data transmission. Multiple sounding APs can transmit a joint sounding packet that includes training symbols for the antennas of all the sounding APs with regard to the transmission channel. The antennas of the multiple sounding APs may be treated as a virtual antenna array with global antenna indexes. The joint sounding packet may include a plurality of training fields, each field corresponding to a respective antenna in the virtual antenna array. Alternatively, the joint sounding packet has subcarrier-interleaved training fields, where each sounding AP transmits training symbols on an allocated set of non-pilot subcarriers. Channel status information (CSI) can be generated by the STAs in response to the joint sounding packet and supplied to the APs. Accordingly, the APs can perform antenna beamforming and transmit a data packet jointly on the transmission channel.

  • Publication number: 20210243693
    Abstract: Systems and methods of transmitting a multi-user (MU) wake-up packet in FDMA. In the wake-up setup stage, an STA informs the AP that it can resolve an MU wake-up packet transmitted in FDMA. Accordingly, AP allocates a frequency channel to the STA in a WUR setup response frame which indicates a channel offset relative to the primary channel. Moreover, if a WUR channel allocated to an STA is inaccessible or there is on pending wake-up signal for the STA, no wake-up signal is included in the MU wake-up packet while any other accessible allocated channels may still be utilized for transmitting the scheduled wake-up signals. During such a transmission, an inaccessible channel may be punctured; and an accessible channel having no pending wake-up signal may be used to carry an invalid wake-up signal or a legacy preamble followed with no wake-up signal.
