1. A base station in a wireless communication system, the base station comprising:
a transceiver; and
a processor coupled with the transceiver and configured to:
transmit, to a user equipment (UE), information indicating second precoding matrix indicators (PMIs) through higher layer signaling; and
receive, from the UE, uplink control information including a first PMI, associated with a channel state information reference signal (CSI-RS), and a channel quality indicator (CQI) without any of the second PMIs,
wherein the CQI is associated with a precoder corresponding to the first PMI and one of the second PMIs, and each of precoders corresponds to the first PMI and each of the different second PMIs, and
wherein the first PMI corresponds to a wideband and each of the precoders corresponds to a frequency resource in the wideband.
