Abstract: Embodiments of the present application provide a beam tracking method, apparatus, and system, which relate to the communications field, so that a relatively high channel capacity can be obtained, and system spectrum efficiency can be improved. The method includes: obtaining, by a communications device, a channel relevance coefficient, and determining a first radio-frequency weighted matrix of the communications device in an (n+1)th timeslot according to the relevance coefficient, where n is an integer, and n≧1; receiving, by the communications device, a first known signal sent by a peer device, and determining an equivalent channel matrix in the (n+1)th timeslot according to the received first known signal; and determining, by the communications device, a digital weighted matrix of the communications device in the (n+1)th timeslot according to the equivalent channel matrix, so as to match a real-time channel and transmit data by using the real-time channel.
