Provided are a method for measuring channel state information and a network node. The method comprises: sending, by a first node, a reference signal resource allocation message to a measurement node group, wherein the first node manages the measurement node group which comprises a plurality of second nodes, and the reference signal resource allocation message comprises an identity identifier of a node used for sending a reference signal in the plurality of second nodes, and resource indication information about a resource that needs to be used when a reference signal for performing a CSI measurement is sent; and receiving a CSI measurement result sent by a plurality of second nodes except for the node sending the reference signal in the measurement node group, the CSI measurement result being fed back by the plurality of second nodes except for the node sending the reference signal in the measurement node group after receiving the reference signal and performing the CSI measurement based on the reference signal. Thus, the CSI measurement efficiency in a wireless backhaul network is improved. |
