发明名称 Method for directing antenna beam, and transceiver in a mobile communication system
摘要 A method for directing an antenna beam, and a transceiver which comprises antenna arrays forming antenna beams in the transmission direction, by means of which beams a signal is transmitted, and which receives signals that propagate via different paths to the transceiver. The transceiver comprises estimating means for estimating directions of arrival of the received signals, when the transceiver receives signals propagated via different paths, measuring means for measuring the strengths of the signals received from different paths of arrival, and beam directing means. The directing means command the antenna array to form in the transmission direction the main antenna beam which is formed in the direction wherefrom the strongest signal is received, if the directions of arrival of the received signals differ only slightly from one another. If the directions of arrival of the received signals differ greatly from one another, the directing means command the antenna array to form, in addition to the main beam, one or more diversity beams, which are formed in the direction, wherefrom a signal exceeding the predetermined threshold value is received.
