  • Patent number: 11063800
    Abstract: Aspects of the disclosure relate to synchronization signaling supporting multiple waveforms. A synchronization signal block (SSB) is configurable for transmission using either at least a first waveform or a second waveform, where the first waveform has higher peak to average power ratio (PAPR) characteristics such as OFDM and the second waveform has lower PAPR characteristics, such as DFT-S-OFDM. The SSB is transmitted selectively using either the first waveform or the second waveform for transmission of the SSB. Furthermore, the characteristics of the transmission such as a predetermined pattern of the first and second waveform transmissions may be utilized to communicate to a receiver the type of waveform being used. In this manner, SSB transmissions may take advantage of respective advantages afforded by each type of waveform, particularly when using higher frequency transmissions above 40 GHz in wireless communication systems.

  • Patent number: 11018964
    Abstract: An apparatus and method that captures a complete history of serial network Link Training negotiations by continuously monitoring multiple analog signals representing both sides of full duplex lanes in real-time by pattern matching the Link Training Frame Marker and the subsequent negotiation request/response data values. The apparatus and method compare the digitized version of the incoming signal against a nominal pattern at the start to find the Frame Markers and Control Channel data, storing only those Control Channel data values that do not match the current compare pattern, and further by updating the current compare pattern to the new pattern just received, so that only the transitions in the data values are stored, thereby vastly reducing the amount of data presented to the user, but nonetheless retaining the complete substantive history of the Link Training negotiations.
