  • Method and apparatus for data frame synchronization of 5G base station
    Patent number: 11683771
    Abstract: The method of synchronizing data frames between 5G baseband processing stations by a global position system (GPS)-integrated local oscillator block control, including the following steps: step 1: synchronize the baseband processor's local oscillator block with the GPS's 1 pps (pulse per second) pulse and generate a 10 ms (millisecond) pulse from the local oscillator; step 2: use the 10 ms synchronous pulse sync monitor block to get the sync offset between this pulse and the GPS 1 pps pulse; step 3: use the control algorithm to reconfigure the local oscillator so that the 10 ms synchronous pulse can follow the 1 pps GPS pulse.
