Abstract
A method and device for acquiring Channel State Information (CSI) are provided. In the method, a second node receives a first-type signal and/or a second-type signal sent by a first node; the second node acquires CSI based on measurement of the first-type signal and the second-type signal, or based on measurement of the second-type signal only; the first-type signal may include a measurement Reference Signal (RS), and the second-type signal may include one of: a demodulation RS, a data sharing channel signal, and a signal combination of the data sharing channel signal and the demodulation RS; the second node feeds back the CSI to the first node.
