1. A method comprising:

  • identifying, by a processor, a ratio between downlink sub-frames and uplink sub-frames for signals communicated via a distributed antenna system;

    determining, by the processor, an initial clock setting that corresponds to the identified ratio and that controls a timing for generating switching signals that instruct at least one switch in an uplink path or the downlink path of the distributed antenna system to switch the distributed antenna system between an uplink mode and a downlink mode the initial clock setting;

    measuring a signal power in a downlink path of the distributed antenna system;

    determining a switching time adjustment based on frame boundaries that correspond to the measured signal power; and

    updating the initial clock setting based on the switching time adjustment.
