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.

Claim (Index 4):
The method of  claim 1 , wherein determining the format of the eBRP packet comprises:\n determining, by the first device, a transmission channel quantity (C), and determining that each eBRP-CE sub-field in the training field is composed of C\u00d7S Gray codes, the S being a positive integer less than nine, and the C being determined by a transmission channel quantity of the first device; determining, by the first device, the C, and determining that the eBRP-CE sub-field in the training field comprises a first eBRP-CE sub-field and a second eBRP-CE sub-field, each first eBRP-CE sub-field being compared of C\u00d7S Gray codes, and each second eBRP-CE sub-field being composed of nine Gray codes, and C being a positive integer greater than or equal to one; or determining, by the first device, the C, and determining that each eBRP-CE sub-field in the training field is composed of C\u00d79 Gray codes, and determining, by the first device, that a quantity of eBRP-CE sub-fields in the training field (N), a quantity of eBRP-TRN sub-fields in the training field (M), and a quantity of Gray codes composing each eBRP-TRN sub-field in the training field (Y) meet a formula 9\u00d7C\u00d7N:Y\u00d7M<9:20.
