Title:
METHOD OF TRANSMITTING CHANNEL STATE INFORMATION, DEVICE, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/127038
Kind Code:
A1
Abstract:
The invention relates to the field of radio communication, and specifically, to a method of transmitting channel state information (CSI), a device, and a system. The method comprises: UE receives downlink signaling transmitted from a base station and carrying a feedback identification; and the UE determines, according to the feedback identification, a CSI characteristic, and performs, according to the CSI characteristic, a channel measurement to obtain CSI to be fed back to the base station; wherein the CSI characteristic comprises at least one of a CSI type, a CSI measurement method, and a CSI feedback opportunity. Since the CSI characteristic comprises at least one of the CSI type, the CSI measurement method, and the CSI feedback, opportunity, the CSI characteristic can include a plurality of combinations of various CSI types and various CSI measurement methods, achieving flexible CSI feedback from UE to a base station.
