Abstract
Provided are a method, an apparatus, a terminal device and a base station for controlling precoding. The method includes: receiving configuration parameters configured by a base station for the precoding, where the precoding is used for feeding back a channel state; determining an upper limit value of a feedback number of coefficients of composition vectors of the precoding according to the configuration parameters; and adjusting the upper limit value of the feedback number.
Claims19
A method for controlling precoding, comprising:
- receiving configuration parameters configured by a base station for the precoding, 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.
