    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.
