Abstract:
A transmit diversity method, a device, and a system are described herein. The method includes: measuring, by a second network device, channel state information based on a pilot signal, and sending rank index information and precoding matrix index information to a first network device based on the channel state information; receiving, by the first network device, the rank index information and the precoding matrix index information that are sent by the second network device; determining a diversity coding scheme based on the rank index information; determining a precoding matrix based on the precoding matrix index information; and performing transmission processing on to-be-transmitted data based on the diversity coding scheme and the precoding matrix.

Claim (Index 12):
The first network device according to  claim 11 , wherein the processor is configured to:\n when the diversity coding scheme is the first diversity coding scheme, process, the first data by using the first diversity coding scheme, to obtain the second data, wherein data symbols of the first data are d(2k), 2k=0, 1, . . . , M symb \u22121, and M symb  represents a quantity of data symbols of the to-be-transmitted data, wherein the first diversity coding scheme is:\n X 2k,1 =d (2 k )  X 2k,2 =d (2 k+ 1) \n X 2k+1,1 =\u2212( d (2 k+ 1))*  X 2k+1,2 =( d (2 k ))* \n wherein X 2k,1  represents a data symbol to which first-layer data is mapped on a 2k th  subcarrier, and corresponds to a data symbol d(2k) of the first data; X 2k+1,1  represents a data symbol to which the first-layer data is mapped on a 2k+1 th  subcarrier, and corresponds to a data symbol \u2212(d(2k+1))* of the first data; X 2k,2  represents a data symbol to which second-layer data is mapped on the 2k th  subcarrier, and corresponds to a data symbol d(2k+1) of the first data; X 2k+1,2  represents a data symbol to which the second-layer data is mapped on the 2k+1 th  subcarrier, and corresponds to a data symbol (d(2k))* of the first data; and data symbols of the second data are represented as X; or the first diversity coding scheme is:\n X 2k,1 =d (2 k )  X 2k+1,1 =d (2 k+ 1) \n X 2k,2 =\u2212( d (2 k+ 1))*  X 2k+1,2 =( d (2 k ))* \n wherein X 2k , represents a data symbol to which first-layer data is mapped on a 2k th  subcarrier, and corresponds to a data symbol d(2k) of the first data; X 2k+1,1  represents a data symbol to which the first-layer data is mapped on a 2k+1 th  subcarrier, and corresponds to a data symbol 2k+) of the first data; X 2k,2  represents a data symbol to which second-layer data is mapped on the 2k th  subcarrier, and corresponds to a data symbol \u2212(d(2k+))* of the first data; X 2k+1,2  represents a data symbol to which the second-layer data is mapped on the 2k+1 th  subcarrier, and corresponds to a data symbol (d(2k))* of the first data; and data symbols of the second data are represented as X.
