Claim 5:
6. 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, and wherein modifying 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 rounding a calculation result down to obtain a number of space domain vectors corresponding to a second class of rank of the transmission layer of the precoding; or
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 rounding a calculation result down to obtain a number of frequency domain vectors corresponding to a second class of rank of the transmission layer of the precoding.
