摘要： In this application, for a CSI-RS resource-related configuration and indication problem, corresponding configuration and indication technologies are designed and include the following: A network device configures CSI-RS resources as a resource set used for channel measurement and a resource set used for interference measurement, and provides a plurality of correspondences between the resource set used for channel measurement and the resource set used for interference measurement. In another implementation, for a CSI-RS resource set, the network device configures that resources in the CSI-RS resource set include both the resource used for channel measurement and the resource used for interference measurement. The network device sends reference signal measurement indication information to a terminal to indicate the resource set used for channel measurement or which resource is used for channel measurement and which resource is used for interference measurement in a set. In this way, the network device performs flexible and diverse configuration on the CSI-RS resource, and reduces indication overheads as many as possible, thereby meeting a requirement of channel and interference measurement performed by a plurality of user terminals in an NR system.

摘要： This application discloses a configuration method for channel state information measurement and a related device. The method includes: generating, by a first network device, parameter information of a resource in which a channel state information CSI reference signal is located, where the parameter information is used by the second network device to determine one or more of the following information of the resource in which the CSI reference signal is located: subcarrier spacing information, cyclic prefix length information, frame structure time length information, and symbol quantity information; and sending, by the first network device, the parameter information to the second network device. In this application, when a base station uses different frame structures in different frequency bands, UE can learn of frame structures of frequency bands in which different CSI-RSs are located, and therefore the UE implements CSI measurement of a neighboring cell.
