    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.

    Abstract: Disclosed is an information transmission method. The method includes that: a first communication node determines a resource or parameter for a second communication node to transmit a reference signal, and indicates the resource or parameter to the second communication node through signaling; and the second communication node receives the signaling transmitted by the first communication node, determines the resource or parameter for transmitting the reference signal based on the signaling or based on the signaling and a rule predefined by the first communication node and the second communication node, and uses the determined resource or parameter to transmit the reference signal.

    Abstract: A method and apparatus for information reporting as well as a method and apparatus for information transmission are provided. The method for information reporting includes: receiving, by a second communication node, a reference signal from a first communication node, to determine a reference signal-related index and/or channel state information; reporting, by the second communication node, a set to the first communication node, and the set includes at least one of: the reference signal-related index and the channel state information. This technical solution solves the problems of low flexibility and poor adaptability of beam-related information reporting in the related art; the second communication node reports its own capability, so that the first communication node can indicate a beam reporting that meets to user capability, thereby improving the stability of beam-related information reporting.
