    摘要： Signals from multiple antennas are evaluated in a wireless device having one receiver chain and the antenna receiving the highest quality signals is selected. The signal quality from the multiple antennas may be evaluated using the short symbols in the preamble or the beacon signals and the antennas dynamically selected to improve the performance of the wireless communications device.

    摘要： Device, system and method of bidirectional wireless communication. In some demonstrative embodiments a method may include, for example, receiving by a wireless communication relay node a superimposed transmission corresponding to first and second transmissions from first and second wireless communication nodes, respectively, wherein the first transmission includes a first packet intended at least for a third wireless communication node; and broadcasting a broadcast transmission including the superimposed transmission from the relay node to a set of two or more wireless communication nodes including the third wireless communication node. Other embodiments are described and claimed.

    摘要： In Spatial Division Multiple Access (SDMA) communications, mobile devices that are transmitting to a base substantially simultaneously during a predetermined communications phase may wait until after an end of the predetermined communications phase to receive acknowledgments to their transmissions, so that a mobile device making a relatively short transmission does not experience an acknowledgement timeout while another mobile device is still completing a relatively long transmission. In some embodiments, the mobile devices may transmit a non-immediate block acknowledgement request during the communications phase.

    摘要： The present disclosure relates to computer-implemented systems and methods for wireless display discovery. The method may include receiving, by a computer, a selection to detect wireless display devices. The computer may include one or more processors, a radio transceiver, and a microphone. The method may also include identifying, by the radio transceiver, a plurality of wireless display device and transmitting, by the radio transceiver, respective connection requests to the plurality of wireless display devices. Additionally, the method may include transmitting, by the radio transceiver to the wireless display devices, respective requests for inaudible audio signal transmission. The method may also include receiving, by the microphone, a plurality of inaudible audio signals from the wireless display devices. Further still, the method may include determining, based at least in part on the plurality of inaudible audio signals, whether any of the plurality of wireless display devices are in the same room as the computer.
