Document Type and Number:
WIPO Patent Application WO/2022/160344
Kind Code:
A1
Abstract:
The present disclosure provides a base station and a terminal. The base station comprises: a receiving unit configured to receive precoding matrix indicator information of a first granularity from a terminal; and a processing unit configured to perform channel reconstruction according to the precoding matrix indicator information to obtain a first channel, use a super-resolution network to perform interpolation and denoising processing on a channel having the first granularity to obtain a second channel, and perform downlink precoding on the second channel, wherein the first channel has the first granularity, the second channel has a second granularity, and the second granularity is finer than the first granularity.
