1. A method for a user equipment, UE, the method comprising:
receiving signaling, by the UE, the signaling including:
a K+1 Non-Zero Power, NZP, NZP channel state information, CSI, reference signal, RS, configuration for K+1 NZP CSI-RS resources that are each shared by K+1 UE candidates;
a first NZP CSI-RS configuration for using a single NZP CSI-RS resource of the configured K+1 NZP CSI-RS resources for channel measurement;
a second NZP CSI-RS configuration for multiple user, MU, interference measurement, the second NZP CSI-RS configuration being for configuring K NZP CSI-RS resources of the configured K+1 NZP CSI-RS resources for the MU interference measurement, where K>=1; and
a CSI interference measurement, CSI-IM, configuration for interference measurement;
receiving a CSI feedback request, the CSI feedback request being associated with the signaled first NZP CSI-RS configuration, the second NZP CSI-RS configuration, and the CSI-IM configuration; and
responsive to the received CSI feedback request, measuring a downlink channel on the single first NZP CSI-RS resource corresponding to the first NZP CSI-RS configuration and measuring MU interference on each of the K NZP CSI-RS resources of the configured K+1 NZP CSI-RS resources that are associated with the second NZP CSI-RS configuration.
