Claim 15:
16. A method for controlling precoding, comprising:
sending configuration parameters configured for the precoding to a terminal device, wherein the precoding is used for feeding back a channel state;
determining, according to the configuration parameters, an upper limit value of a feedback number of coefficients of composition vectors of the precoding; and
adjusting the upper limit value of the feedback number;
wherein adjusting the upper limit value of the feedback number comprises: modifying at least one configuration parameter or at least one control parameter that affects the upper limit value of the feedback number, and modifying the upper limit value of the feedback number by using the modified at least one configuration parameter or the modified at least one control parameter; and
wherein the at least one control parameter that affects the upper limit value of the feedback number comprises a number of frequency domain vectors of the precoding, and wherein modifying the at least one control parameter that affects the upper limit value of the feedback number comprises:
determining, based on the number of frequency domain vectors, a value range of an influence parameter of the upper limit value of the feedback number.
