Method and apparatus used in node for wireless communication

Abstract

The present application discloses a method and apparatus used in a node for wireless communication. The method comprises: receiving a first CSI reporting configuration, wherein the first CSI reporting configuration indicates a first resource set, and the first resource set consists of one or more aperiodic CSI-RS resources; performing a first operation, wherein an input of the first operation depends on measurement based on the first resource set; and sending a first signal, wherein the first signal carries a target CSI report, and the target CSI report depends on an output of the first operation. The target CSI report comprises channel information of N time units, and N is a positive integer. The number N depends on the number of RS resources in the first resource set that have transmission occasions not later than a transmission occasion of a reference resource, and the reference resource is not later than the first signal in a time domain. The method improves the accuracy and real-time performance of channel information reporting.
