Interference measurement indication method, interference measurement method, related device, and communication system

An interference measurement method, comprising:

• receiving, by a user equipment, at least one piece of first-type channel state information reference signal (CSI-RS) configuration signaling transmitted by a base station, wherein the at least one piece of first-type CSI-RS configuration signaling indicates a first resource set used for CSI-RS transmission;
• receiving, by the user equipment, at least one piece of second-type CSI-RS configuration signaling transmitted by the base station, wherein a second resource set used for CSI-RS transmission, which is indicated by the at least one piece of second-type CSI-RS configuration signaling, is a subset of the first resource set;
• and
• performing, by the user equipment, an interference measurement in a resource position corresponding to the second resource set.

A user equipment, comprising:

• a first receiving module, configured to receive at least one piece of first-type channel state information reference signal (CSI-RS) configuration signaling transmitted by a base station, wherein the at least one piece of first-type CSI-RS configuration signaling indicates a first resource set used for CSI-RS transmission;
• a second receiving module, configured to receive at least one piece of second-type CSI-RS configuration signaling transmitted by the base station, wherein a second resource set used for CSI-RS transmission, which is indicated by the at least one piece of second-type CSI-RS configuration signaling, is a subset of the first resource set;
• and
• an interference measurement module, configured to perform an interference measurement in a resource position corresponding to the second resource set.
