An antenna mode selection method, apparatus and system, which relate to the field of communications, are used for antenna mode selection and can reduce the time of the antenna mode selection, so as to increase the speed of the antenna mode selection and improve the efficiency. The method comprises: a sending apparatus which sends N pilot frequency signals and N pieces of corresponding antenna index information to a receiving apparatus in a subframe (201); the sending apparatus receives antenna mode indication information sent by the receiving apparatus (202); and the sending apparatus takes a transmission mode corresponding to the antenna index information contained in the antenna mode indication information as an optimal transmission mode of the receiving apparatus (203). |
