Abstract
A methods and apparatuses are provided for transmitting and receiving channel state information (CSI). A method by a user equipment (UE) includes receiving, from a base station (BS), first configuration information configuring a first interference measurement resource (IMR) and a second IMR in case that the UE is configured with CSI subframe sets; receiving, from the BS, second configuration information configuring a zero-power (ZP) CSI-reference signal (CSI-RS) resource; and transmitting, to the BS, a CSI based on the first configuration information and the second configuration information. The ZP CSI-RS resource includes the first IMR and the second IMR.

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.
