Title:
METHOD AND APPARATUS FOR ACQUIRING CHANNEL QUALITY, STORAGE MEDIUM AND CHIP
Document Type and Number:
WIPO Patent Application WO/2023/221061
Kind Code:
A1
Abstract:
The present disclosure relates to a method and apparatus for acquiring channel quality, a storage medium and a chip. The method comprises: a terminal device receiving a pilot signal, which is sent by a network device through a downlink channel; acquiring a first channel matrix according to the pilot signal; compressing the first channel matrix according to a channel state information (CSI) compression model and a CSI compression parameter, so as to obtain a compressed target channel matrix; and sending the target channel matrix to the network device, such that the network device determines the channel quality of the downlink channel according to the target channel matrix. The first channel matrix is used for representing the channel quality of the downlink channel. The CSI compression model comprises a channel encoder, and the channel encoder comprises a plurality of sub-encoders; and different sub-encoders correspond to different CSI compression parameters. The target channel matrix is used for instructing the network device to determine the channel quality of the downlink channel.
