Claim 6:
7. The method according to claim 1, wherein control parameters that affect the upper limit value of the feedback number comprise a number of space domain vectors of the precoding and the number of frequency domain vectors of the precoding, the configuration parameters comprise the number of space domain vectors, an influence parameter of the number of frequency domain vectors and the influence parameter of the upper limit value of the feedback number, and wherein modifying the at least one configuration parameter or the at least one control parameter that affects the upper limit value of the feedback number comprises at least one of:
calculating a number of space domain vectors corresponding to a first class of rank of a transmission layer of the precoding by using a first proportional function, and taking a larger of a calculation result and a preset value of the number of space domain vectors as a number of space domain vectors corresponding to a second class of rank of the transmission layer of the precoding;
calculating a number of frequency domain vectors corresponding to a first class of rank of a transmission layer of the precoding by using a second proportional function, and taking a larger of a calculation result and a preset value of the number of frequency domain vectors as a number of frequency domain vectors corresponding to a second class of rank of the transmission layer of the precoding;
calculating an influence parameter of a number of frequency domain vectors corresponding to a first class of rank of a transmission layer of the precoding by using a third proportional function, and taking a larger of a calculation result and a preset value of a first influence parameter as an influence parameter of a number of frequency domain vectors corresponding to a second class of rank of the transmission layer of the precoding; or
