Document Type and Number:
WIPO Patent Application WO/2022/217506
Kind Code:
A1
Abstract:
A channel information feedback method, a sending end device, and a receiving end device, which are advantageous for feedback precision of channel information and CSI feedback overhead. The method comprises: the sending end device receiving a reference signal sent by the receiving end device; performing channel estimation according to the reference signal to obtain channel information between the sending end device and the receiving end device; performing feature decomposition on the channel information to obtain at least one first feature vector; encoding the at least one first feature vector by means of a neural network to obtain a target bit stream; and sending the target bit stream to the receiving end device.
