    Abstract: A method for transmitting channel state information (CSI) on multiple base stations (BSs) in a wireless communication system. A user equipment (UE) receives information on periodic reporting configuration of CSI including a rank indicator (RI) and a first type precoding matrix indicator (PMI) with respect to a first BS and information on periodic reporting configuration of CSI including a RI and a first type PMI with respect to a second BS. The UE transmits CSI on the first BS and the second BS on the basis of CSI reporting configuration with respect to the first BS and the second BS. Additional CSI including aggregated CSI generated by aggregating signals from the first BS and the second BS is transmitted at the time when a report on one of a first type PMI and the RI is omitted.
