Claim Text:
1. A method for frame-start synchronization with nearby base stations in a macro network, the method comprising: (a) a second base station receiving a first signal from a first base station in the macro network, wherein the first signal comprises frames, and wherein the first signal further comprises an identifier of the first base station; (b) the second base station synchronizing a frame-start timing signal with the frames in the first signal; (c) the second base station determining a time-of-flight delay between the first base station and the second base station; (d) the second base station adjusting timing of the frame-start signal to account for the time-of-flight delay between the first base station and the second base station; and (e) the second base station broadcasting a second signal that is formatted into frames, wherein the second base station uses the frame-start timing signal to control timing of the frames in the second signal.
