Abstract
Disclosed are a CSI-RS configuration and CSI feedback method and apparatus, and a relevant device, which are used for implementing 16-port CSI-RS configuration and performing CSI feedback based on a 16-port CSI-RS. The CSI-RS configuration method comprises: determining 16-port channel state information-reference signal (CSI-RS) configuration information configured to a user equipment (UE), wherein the CSI-RS configuration information comprises information about a resource element (RE) occupied by a 16-port CSI-RS configured to the UE, and the RE occupied by the 16-port CSI-RS comprises an RE other than REs occupied by a physical downlink control channel (PDCCH), a cell-dedicated reference signal (RS) and a UE-dedicated RS; and sending, to the UE, the 16-port CSI-RS configuration information configured to the UE.
