摘要： Radio Frequency (RF) systems configured to implement full-duplex wireless data transfer for rotary joints are disclosed. An example RF system includes a 60 GHz short distance communication link implemented using elliptically (e.g., circularly) polarized antennas. Such a system may provide a mm-wave, high-speed, wideband wireless communication link in a manner that is associated with simpler design and operation, mechanical integrity, and reduced power consumption, compared to alternative solutions.

摘要： Different filtered-orthogonal frequency division multiplexing (f-OFDM) frame formats may be used to achieve the spectrum flexibility. F-OFDM waveforms are generated by applying a pulse shaping digital filter to an orthogonal frequency division multiplexed (OFDM) signal. Different frame formats may be used to carry different traffic types as well as to adapt to characteristics of the channel, transmitter, receiver, or serving cell. The different frame formats may utilize different sub-carrier (SC) spacings and/or cyclic prefix (CP) lengths. In some embodiments, the different frame formats also utilize different symbol durations and/or transmission time interval (TTI) lengths.

摘要： Multiple channels are aggregated. In an example embodiment, first data is transmitted on a first channel to a wireless device, and second data is simultaneously transmitted on a second channel to the wireless device. The first data and the second data are transmitted in a coordinated manner by aggregating the first channel and the second channel. Various example channel characteristics and combinations thereof are described. Different data allocation options for aggregated channels are described. Other alternative implementations are also presented herein.

摘要： In accordance with one or more embodiments, a transmission device operates by: generating a transmit signal conveying transmit data in accordance with an HARQ protocol; converting the transmit signal to transmitted guided electromagnetic waves that propagate along a surface of a transmission medium; converting to a receive signal received guided electromagnetic waves that propagate along the surface of the transmission medium; generating, based on the receive signal, corona discharge data that indicates a corona discharge in proximity to the transmission medium during a first time period; identifying, responsive to the corona discharge data, a first packet of the transmit signal that was converted to transmitted guided electromagnetic waves during the first time period; and regenerating the transmit signal to include the first packet for retransmission via the transmitted guided electromagnetic waves, without waiting for a repeat request to be received from the remote device indicating the first packet.

摘要： A first communication device in a wireless local area network (WLAN) selects an aggregate communication channel from a first set of one or more allowed non-overlapping aggregate communication channels that is wholly within a first radio frequency (RF) sub-band that is adjacent in frequency to a second RF sub-band. The second RF sub-band includes a second set of one or more allowed non-overlapping aggregate communication channels that is wholly within the second RF sub-band and that is separated in frequency from the first set of allowed aggregate communication channels by a gap in frequency. The gap in frequency is smaller than a cumulative bandwidth of two component communication channels in the first RF sub-band. The method also includes: using, at the first communication device, the selected aggregate communication channel to transmit a packet to one or more second communication devices in the WLAN.
