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.
