  • Patent number: 11743768
    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: 11265048
    Abstract: Systems and methods of transmitting a PPDU to or from a single user station (STA) in an MIMO transmission by using unequal MCSs. An access point (AP) allocates a plurality of spatial streams to the STA and assigned them into groups for the MIMO transmission. Multiple unequal MCSs are assigned to the different spatial stream groups. Correspondingly the STA ID is repeatedly specified in the user block fields of a SIG-B field of 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 block fields 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 grouped-based unequal MCSs scheme is used for the MIMO transmission.

  • 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.

  • Patent number: 10616017
    Abstract: Modulation schemes that use dual sub-carrier to reliably transmit physical layer related signaling information and/or data in high efficiency wireless local area network (HE WLAN) are proposed. The proposed schemes can be implemented with low complexity and provide better performance than existing modulation schemes used in WLAN that are based on IEEE 802.11/a/b/g/n/ac standards. The proposed schemes enhance the reliability of transmissions, especially under narrow band interferences. In accordance with a novel aspect, dual subcarrier modulation (DCM) is introduced in HE WLAN. DCM can introduce frequency diversity into OFDM systems by transmitting the same information on two subcarriers separated in frequency. A DCM indication scheme is used such that both encoding and decoding of DCM is really simple.

  • Patent number: 10516457
    Abstract: A method of enhanced beamforming procedure to achieve spatial reuse and thereby improving cell edge performance and area throughput is proposed. The enhanced beamforming method increases the likelihood of channel access under dense deployment condition, reduces interference to OBSS, reduces collision during reception, and increases the likelihood of spatial reuse in dense deployment scenario thus leading to higher network throughput.

  • Patent number: 10405139
    Abstract: An emergency mode is provided in a portable electronic device for locating a survivor in a disaster. The device includes a wireless antenna to transmit and receive wireless signals; a memory to store one or more identifiers; a user interface to receive a command that enables the emergency mode. The device also includes one or more processors, which, in response to the command, detect via the wireless receiver a predetermined identifier that matches a stored identifier identifying a sender of the predetermined identifier as a trusted node. When the predetermined identifier and a timing measurement frame are received from the trusted node, the device sends a response to the trusted node to indicate its presence.

  • Patent number: 10187124
    Abstract: A method of transmitting and receiving a HE PPDU and perform channel estimation enhancement is proposed. The HE PPDU comprises legacy preamble, HE-STF, HE-LTF, and data. A beam-change indication indicates if the pre-multiplied beamforming Q-matrix is changed from legacy preamble to H-SFT, HE-LTF, and data portion. A value of 1 indicates that Q matrix is changed. A value of 0 indicates that Q matrix is unchanged and receiver should be safe to combine L-LTF and HE-LTF. The beam-change indication can be used to significantly enhance channel estimation at receiver. When there is no beam-change, receiver does not change operation during HE-STF and HE-LTF such that the channel estimations can rely on the combination of L-LTFs, L-SIG, RL-SIG, HE-SIGAs and HE-LTF.

  • Patent number: 10178686
    Abstract: A method of channel contention procedure with CCA level enhancement is proposed. A wireless device initiates an EDCA channel contention procedure to gain access to the wireless medium. The device determines an intended TX channel width and performs primary channel CCA using a set of CCA levels based on the intended TX channel width for determining channel idle or busy condition in the EDCA procedure. Upon gaining access, the device performs secondary channel CCA and thereby determining a final TX channel width. The device transmits radio signals using the final TX channel width and a TX spectral power density, which is adjusted to be corresponding to the intended TX channel width. By raising CCA levels to be based on the intended transmission channel width, the likelihood of wide channel width transmission is increased. As a result, significant network throughput increase can be accomplished in dense deployment scenarios.

  • Patent number: 10104493
    Abstract: A method of indoor positioning using Fine Timing Measurement (FTM) protocol with multi-antenna access point (AP) is proposed. In a wireless local area network, an AP has multiple antennas that are strategically located in different physical locations. The AP is used to exchange FTM frames with a wireless station for timing measurement of the FTM frames via its multiple antennas independently. The timing measurement result (e.g., timestamps of transmitting and receiving FTM frames) is then used to determine an absolute location of the station. A simplified Indoor Location operation with simplified deployment is achieved.
