ABSTRACT:
The present invention provides a method of coordinating transmission by and reception by a plurality of antennas associated with a plurality of radio heads. The method includes determining, at a controller, at least one relative time delay associated with a plurality of backhaul links between the controller and the plurality of radio heads. The method also includes providing information indicative of a first signal over the plurality of backhaul links. The method further includes providing timing information over the plurality of backhaul links. The timing information is determined based on the relative time delay(s) such that the plurality of radio heads can use the provided timing information to coherently transmit the first signal using the plurality of antennas and a plurality of controllers to receive mobile unit transmitted information.
