1. A method for transmitting channel state information (CSI) by a user equipment (UE), the method comprising:
receiving, from a base station (BS), first configuration information configuring a first interference measurement resource (IMR);
receiving, from the BS, second configuration information configuring a second IMR in case that the UE is configured with CSI subframe sets;
receiving, from the BS, third configuration information configuring a zero-power (ZP) CSI-reference signal (CSI-RS) resource; and
transmitting, to the BS, a CSI,
wherein the ZP CSI-RS resource overlaps with the first IMR and the second IMR,
wherein the first configuration information includes a first subframe configuration, and a first resource configuration for resource elements (REs), and
wherein the second configuration information includes a second subframe configuration, and a second resource configuration for REs.
