  • Publication number: 20190373583
    Abstract: A beamforming training packet is transmitted from a first communication device to multiple second communication devices. A trigger frame is generated at the first communication device to trigger an uplink orthogonal frequency division multiple access (OFDMA) transmission of beamforming training feedback from at least some of the multiple second communication devices. After transmission of the beamforming training packet by the first communication device, the trigger frame is transmitted to the at least some of the multiple communication devices. The uplink OFDMA transmission is then received at the first communication device. The uplink OFDMA transmission includes respective beamforming training feedback packets generated based on the beamforming training packet by respective ones of the at least some of the multiple second communication devices. The respective beamforming training feedback packets are simultaneously transmitted by the at least some of the multiple second communication devices.

    Abstract: A communication system includes a first basic service set (BSS) having a first plurality of nodes including a first node, and a second BSS overlapping the first BSS and having a second plurality of nodes including a second node. Upon receipt, from the second node, of a signal specifying a transmission duration, the first node operates at a reduced power level for a total time interval triggered by the signal. The total time interval may include a backoff duration of the first node, a transmit opportunity period (TXOP) of the first node, and a fixed grace period following the TXOP of the first node. A method of operating a node in such a system includes receiving, at the first node, a signal from the second node specifying a transmission duration, and operating the first node at a reduced power level for a total time interval triggered by the signal.

    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.
