<p>The present invention is a method for adjusting the uplink transmission power of a WTRU utilizing a switched beam antenna. The method measures the received power of a pilot channel beacon in order to estimate the path loss associated with each directional antenna beam. A beam correction function is calculated based on an estimated gain difference between the beam which is currently used for transmission and the beam to which the WTRU will switch. The transmission power of the WTRU is adjusted according to the beam correction function at the time of beam switching. The beam correction function is equivalent to the response of the WTRU's averaging function to the estimated gain differenceto a step function representing the difference in gain between said first and said second beams, after a beam switch, offset by the same estimated gain difference.the averaged power of a pilot channel beacon received by the WTRU after a beam switch offset by the estimated gain difference between the old beam and the new beam.</p> |
