  • Patent number: 10791516
    Abstract: The present disclosure describes methods and apparatuses for improved target wake time (TWT) operations in wireless networks. In some aspects, an access point transmits a trigger frame to stations of a TWT session during a TWT service period. Responsive to the trigger frame, the access point receives respective uplink frames transmitted by the stations. The access point then transmits a multi-block acknowledgment (M-BA) frame with a per association identifier traffic identifier (per AID TID) field configured to indicate whether one or more of the stations are permitted to enter a low-power state before an end of the TWT service period. By so doing, stations that are typically unable to interpret a more data field of the M-BA frame can determine based on the per AID TID if they are permitted to enter the low-power state and conserve power during a remainder of the TWT service period.

  • Publication number: 20200304173
    Abstract: A first access point (AP), which is associated with one or more first client stations, generates an announcement frame that announces a coordinated multi-user (MU) transmission involving multiple APs including the first AP and one or more second APs. Each of the second APs is associated with a respective one or more second client stations. The announcement frame is generated to indicate respective one or more frequency resource units (RUs) allocated to the one or more second APs for the coordinated MU transmission. The first AP transmits the announcement frame to the one or more second APs to initiate the coordinated MU transmission, and participates in the coordinated MU transmission while the one or more second APs also participate in the coordinated MU transmission.

  • Patent number: 10778392
    Abstract: A method for communication over a wireless interface between transceivers that are moving with respect to each other. The method includes transmitting, by a communication station (STA) in a moving vehicle over a wireless channel to a receiver outside the vehicle, a sequence of data symbols encoded in accordance with a frequency-domain multiplexing scheme extending over a range of sub-carrier tones. A condition affecting the wireless channel is evaluated. Responsively to the evaluated condition, a pilot scheme is selected from among a plurality of available pilot schemes, for interleaving of pilot signals in specified sub-carrier tones of the data symbols. An indication of the selected pilot scheme is exchanged between the STA and the receiver. The pilot signals are interleaved in the transmitted data symbols in accordance with the selected pilot scheme.

  • Patent number: 10754149
    Abstract: Techniques for correcting image data in a lens shading correction circuit include accessing numerical constants associated with channels of a captured image represented by a pixel array from a memory. The techniques further include calculating lens shading correction factors for the captured image for each pixel of a channel in the pixel array according to the x-y pixel position of the pixel based on a lens shading correction formula and the numerical constants. For the channel in the pixel array, the correction formula applies different subsets of the numerical constants to different radial portions of the pixel array. The techniques also includes performing lens shading correction for the captured image based on the calculated lens shading correction factors to produce corrected image data, and storing the corrected image data in a non-transitory computer-readable medium.
