Title:
METHOD FOR MEASURING CHANNEL STATE INFORMATION, TERMINAL DEVICE, AND NETWORK DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/134570
Kind Code:
A1
Abstract:
The present application provides a method for measuring channel state information (CSI), a terminal device, and a network device. The method comprises: a terminal device receiving downlink control information, the downlink control information carrying measurement information for CSI measurement, the measurement information at least comprising CSI-RS resource configuration indication information, to indicate a CSI-RS resource; receiving one piece of downlink control information within a preset period of time, and the terminal device performing CSI measurement on the basis of measurement information carried in only one piece of downlink control information, or alternatively, performing every CSI measurement on the basis of measurement information carried in at least two pieces of downlink control information received in the preset period of time. Therefore, the terminal device can determine a measurement type autonomously according to the amount of downlink control information received in a preset period of time, thereby reducing signaling overhead. A network device can also determine an appropriate transmission scheme and scheduling policy according to measured CSI, thereby facilitating an improvement in the reliability of data transmission.
