Title:
CODING METHOD, DECODING METHOD, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/073578
Kind Code:
A1
Abstract:
Provided in the embodiments of the present invention are a coding method, a decoding method, and a device, related to the technical field of communications, for solving the problem of low PMI accuracy found in a conventional CSI transmission process. The methods comprise: submitting N PMIs to a network device, where each PMI corresponds to one channel, a first PMI comprises channel information of the channel corresponding to a second PMI, the first PMI is one among the N PMIs, the second PMI is at least one PMI preceding the first PMI, and N is a positive integer greater than 1. The present application is applicable in a CSI transmission scenario.
