Title:
DATA TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/042177
Kind Code:
A1
Abstract:
The present application provides a data transmission method and a device. The method comprises: a terminal device receiving a first reference signal transmitted by a network device; the terminal device performing, according to the first reference signal, measurement on a downlink channel, so as to obtain a channel state of the downlink channel; and the terminal device determining, according to the channel state of the downlink channel, a target mode from a plurality of modes. The information used to feedback channel state information (CSI) sent by the terminal device is different when the same is sent via different modes comprised in the plurality of modes. The terminal device transmits indication information to the network device, wherein the indication information is used to indicate the target mode. The data transmission method and device provided in the embodiments of the present application improve the flexibility of CSI feedback.
