Abstract
An apparatus and method of steering a signal from a base station is disclosed. The base station comprises one or more antenna arrays, one or more channel units, the channel units comprising means for phasing the signal to be transmitted and received in such a way that the gain from the antenna array is greatest in a specified direction. Further, the base station includes means for distinguishing connection quality information from information received from the mobile station. In order to improve the spectral efficiency and the connection quality, the channel unit comprises means for searching for the incoming directions and delays of the received signal components, and means for controlling the phasing means of the signal transmitted to the mobile on the basis of the information and the connection quality information received from the mobile station.
