Title:
COMMUNICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/160963
Kind Code:
A1
Abstract:
The present application provides a communication method and apparatus. The method comprises: receiving configuration information from a first device, the configuration information comprising first information, second information, and third information; the first information being indication information of K reference signals, the second information being indication information of K first spatial filtering parameters corresponding to the K reference signals, and the third information being indication information of a channel sparse basis matrix of a channel between the first device and a second device; receiving the K reference signals from the first device; and sending channel state indication information to the first device, the channel state indication information being determined according to K received measurement values of the K reference signals, the K first spatial filtering parameters, and the channel sparse basis matrix. By means of the method, the first device is only required to send a small amount of reference signals, and the second device may complete channel estimation on the basis of the configuration information and then determines the channel state indication information on the basis of the estimated channel, thereby reducing reference signal overhead and time overhead.
