The transmission directivity antenna control system, base station and the transmission directivity antenna control method of using for those

摘要

It designates that the base station whose it is possible to select more optimum beam from midst of the transmission beam of the multiple beam, is offered as purpose, as for the constitution as for beam electrical sensing station 4 calculates the reception signal electric power M of the multiple beams respectively, in beam power selective section 5 from information of received power from of beam electrical sensing station 4, among the outputs M the beam former 31 - 3M, selects the beam of largest electric power and receives the signal. In transmission weight formation department 6 the beam and the optional beam other than that which correspond to the signal of the spread mark which the mobile station selects from the information which is received are selected, the respective transmission weight factor is notified. As for transmission beam forming section 7 transmission weight factor weight is acquired to the transmit data which corresponds to each transmission array antenna element 91 - 9N. As for diffuser 81,82 the input signal it spreads with the spread mark which differs respectively, the transmission array antenna element 91 - 9N the beam forwards the signal which is formed.
