Abstract:
A method implemented in a radio head of selecting a control signaling bus from a plurality of available control signaling busses, said method comprising:determining propagation delays along at least two of said control signaling busses from a corresponding control interface to a first radio head; automatically selecting, by said first radio head, a primary control signaling bus from amongst said plurality of available control signaling busses based on said propagation delays; forming a cascaded radio head chain comprising said first radio head and said at least two control signaling busses prior to said determining propagation delays; subsequently changing the physical configuration of said radio head chain; thereafter, re-determining the propagation delays alone said at least two control signaling busses from said corresponding control interfaces to said first radio head; and thereafter, automatically re-selecting, by said first radio head, a primary control signaling bus from amongst said plurality of available control signaling busses based on said re-determined propagation delays.
