Abstract: A beam refinement method and a communications device, where the method includes determining, by a first device, a format of an enhanced Beam Refinement Protocol (eBRP) packet, where the eBRP packet includes a training field, the training field includes an eBRP channel estimation (eBRP-CE) sub-field and an eBRP training (eBRP-TRN) sub-field, and a ratio of a quantity of Gray codes composing the eBRP-CE sub-field in the training field to a quantity of Gray codes composing the eBRP-TRN sub-field in the training field is less than 9:20, and sending, by the first device, the eBRP packet to a second device based on the determined format of the eBRP packet. Hence, an effective proportion of the eBRP-TRN sub-field in the training field can be increased such that more Antenna Weight Vector (AWV) configurations can be attempted within a same period of time.
