Title:
CODEBOOK DETERMINATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/088501
Kind Code:
A1
Abstract:
The present invention relates to a codebook determination method and device. The codebook determination method comprises: receiving codebook configuration information; obtaining the actual number of first sub-bands according to the codebook configuration information, wherein the first sub-bands are used for performing precoding calculation; and performing precoding calculation according to the actual number of the first sub-bands to obtain a codebook. By receiving the codebook configuration information, and then obtaining, according to the codebook configuration information, the actual number of the first sub-bands used for performing precoding calculation, thereby performing precoding calculation according to the actual number of the first sub-bands to obtain the codebook, the codebook can be determined according to the actual number of the first sub-bands, and the occurrence of the situation that the number of the used first sub-bands is inconsistent with the actual number of the first sub-bands in a process of determining the codebook by means of precoding calculation is reduced, so that the reliability of a codebook determination result is improved, and the precoding accuracy is further improved.
