Claim:
A method for coordinating the use of beam forming between a base station and a wireless transmit/receive unit (WTRU) wherein control information regarding the use of beam forming is not communicated between the base station and the WTRU, the method comprising the steps of: selecting one of the base station and the WTRU for reduction of the amount in which the selected base station or WTRU will adjust its beam in response to misalignment between beams emanating from the base station and the WTRU; measuring an error in the alignment of the beams emanating from the base station and the WTRU; determining a correction factor based on the measured error; selecting at least one adjustment parameter for adjusting the beam of the selected base station or WTRU; and adjusting the beam of the selected base station or WTRU using the selected adjustment parameter in accordance with the correction factor, whereby the beams emanating from the base station and the WTRU are aligned with respect to each other.
