  • Synchronization of large antenna count systems
    Patent number: 9577729
    Abstract: Techniques are disclosed relating to synchronization of radios in a large antenna count (LAC) system. In some embodiments, a LAC system includes a plurality of slave radios, a clock and trigger distribution system, and a master device. In these embodiments, the plurality of slave radios are configured to establish a fixed relationship between a reference clock and their respective local clocks. In these embodiments, the master device and plurality of slave radios are configured to generate and align respective common periodic time reference (CPTR) signals, at a lower frequency than the local clocks. In these embodiments, the master device is configured to transmit a trigger signal based on its CPTR and the plurality of slave radios are configured to perform an action based on the trigger at a subsequent edge of their CPTRs. This may allow synchronization of sampling for antennas in a massive MIMO base station, for example.
