Document Type and Number:
WIPO Patent Application WO/2023/173434
Kind Code:
A1
Abstract:
The present disclosure belongs to the technical field of communications. Provided are a channel estimation method, apparatus and device, and a storage medium. The method comprises: determining configuration information, wherein the configuration information comprises a reference signal mode supported by a UE, and/or, reference signal configuration information of at least one reference signal corresponding to the reference signal mode supported by the UE; sending an indication message to the UE, wherein the indication message is used for indicating a reference signal mode, and/or, for indicating reference signal configuration information of at least one reference signal corresponding to a reference signal mode indicated by a network device; acquiring a reference signal sent by the UE; and executing, on the basis of the reference signal, an operation corresponding to the reference signal mode indicated by the network device, so as to perform channel estimation. The present disclosure provides a channel estimation method based on AI and/or ML, which can improve the channel estimation performance and ensure the accuracy and precision of channel estimation.
