1. A method comprising:

  • transmitting a pilot signal with a first set of spatial parameters for use as a phase reference by a remote terminal;

    transmitting a first user-specific traffic signal with a second set of spatial parameters different from the first set of spatial parameters directed to the remote terminal; and

    transmitting a second user-specific diversity traffic signal with a third set of spatial parameters different from the second set of spatial parameters directed to the remote terminal, the second traffic signal carrying the same traffic as the first traffic signal.
