<p>The present invention discloses a method and a device of sending and receiving precoding information, where the method includes: obtaining, by a terminal, a wideband precoding matrix indicator PMI; separately encoding, by the terminal, an MSB of the wideband PMI or jointly encoding the MSB of the wideband PMI and other information of N bits to obtain encoded information, where the MSB is a part of the wideband PMI, and N is a natural number; and sending, by the terminal, the encoded information to a data sending end. In the embodiments of the present invention, the MSB in the wideband PMI is separately encoded and sent, or the MSB in the wideband PMI and other information of N bits are jointly encoded and sent, which improves reliability of wideband precoding information, and reduces error propagation, thereby further improving the precoding performance.</p> |
