Abstract

Disclosed are an interference measurement indication method an interference measurement method a related device and a communication system. The interference measurement indication method comprises: a base station transmitting to a user equipment (UE) at least one first class channel state information reference signal (CSI RS) configuration signaling where the first class CSI RS configuration signaling indicates a first resource set used for CSI RS transmission; and the base station transmitting to the UE at least one second class CSI RS configuration signaling where the at least one second class CSI RS configuration signaling indicates a second resource set used for CSI RS transmission is a subset of the first resource set. The technical solution provided in embodiments of the present invention facilitates the flexibility of UE interference measurement.
