Abstract:
1. A method for transmitting channel state information (CSI) on multiple base stations in a wireless communication system, the method performed by a user equipment and comprising: receiving first CSI configuration information on a report of CSI, which includes at least one of a rank indicator (RI), precoding matrix indicator (PMI) and channel quality indicator (CQI) of a first base station; receiving second CSI configuration information on a report of CSI, which includes at least one of an RI, PMI and CQI of a second base station; and transmitting CSI on the first base station and CSI on the second base station on the basis of the first CSI configuration information and the second CSI configuration information, wherein a parameter of part or all of the second CSI configuration information is set to a value equal to a parameter corresponding to the first CSI configuration information, and wherein when a CSI report period and offset parameter of the second CSI configuration information is set to a value equal to a CSI report period and offset parameter of the first CSI configuration information, the CSI on the first base station and the CSI on the second base station are transmitted through one uplink container.
