Abstract
(EN)
The present application provides a transmission channel state sending method and device, a transmission channel state receiving method and device, and a storage medium. The transmission channel state sending method comprises: determining a channel state report for representing a precoding channel state; and sending the channel state report for representing the precoding channel state. The channel state report comprises: the number of reported coefficients in a precoding coefficient matrix and the reported coefficients in the precoding coefficient matrix, and the reported coefficients in the precoding coefficient matrix are used for indicating the reported precoding.
