<p>The invention relates to a method for steering an antenna beam, and a base station equipment comprising one or more antenna arrays (500, 700-704, 772-776) consisting of several elements, one or more channel units (504-508, 738-742) which channel unit comprises means (600-608, 706, 770) for phasing the signal to be transmitted and received by the antenna array (500, 700-704, 772-776) in such a way that the gain from the antenna array is the greatest in the desired direction. In order to improve the spectral efficiency of the system, the channel unit (504-508, 738-742) comprises means (604, 732, 802) for searching for the incoming directions and delays of the received signal components, and means (604, 744, 802) for controlling the phasing means (606, 770) of the opposite transmission direction on the basis of said information.</p> |
