Abstract:
1. A method for synchronization of assemblies in a base station with a reference clock signal, comprising: forming a local clock signal and a frame by a first assembly; transmitting the local clock signal and the frame to a second assembly by using a synchronous transmission with a predictable propagation time; receiving the reference clock signal at the second assembly; determining a phase difference and a time difference at the second assembly, the phase difference and the time difference being determined between the local clock signal and the frame, on the one hand, and the reference clock signal, on the other hand; transmitting the phase difference and the time difference from the second assembly to the first assembly via a link without a predictable propagation time; and using the phase difference and the time difference at the first assembly to determine a manipulated variable that controls formation of the local clock signal such that the first and second assemblies are synchronized in time.
