Claim 12:
13. A method performed by a base station for configuring a user equipment, the method comprising:
sending, to a user equipment, a semi-static indication of one or more sets of Non-Zero Power, NZP, Channel State Information Reference Signal, CSI-RS, resources for channel measurement;
sending, to the user equipment, a semi-static indication of one or more sets of NZP CSI-RS resources for interference measurement; and
sending, to the user equipment, one or more dynamic indications that indicate a first set of NZP CSI-RS resources from the one or more sets of NZP CSI-RS resources for channel measurement and a second set of NZP CSI-RS resources from the one or more sets of NZP CSI-RS resources for interference measurement;
wherein: the first set of NZP CSI-RS resources contains a single NZP CSI-RS resource with one or more CSI-RS ports;
the second set of NZP CSI-RS resources contains one or more NZP CSI-RS resources; and
each CSI-RS port in the second set of NZP CSI-RS resources corresponds to a Multiple User Multiple Input Multiple Output, MU-MIMO, interference layer associated with a co-scheduled user equipment.
