    Abstract: A method of transmitting channel state information. The method includes receiving, from a base station, channel measurement information comprising a plurality of antenna ports to be measured for a serving cell; measuring signals related to the plurality of antenna ports based on the channel measurement information; transmitting reference signal received power (RSRP) information for the plurality of antenna ports based on the measured signals; receiving, from the base station, in response to transmission of the RSRP information, channel state information (CSI) report instruction information for a candidate of a distributed antenna port set including at least one antenna port; measuring a channel state of the at least one antenna port in the candidate; and transmitting the measured channel state to the base station, wherein the candidate of the distributed antenna port set among the plurality of antenna ports is determined based on the RSRP information by the base station.
