1. A method for transmitting information for at least one of measurement reporting and channel state information (CSI) reporting of a user equipment (UE) by a serving cell performing coordinated multipoint (CoMP) transmission with heterogeneous bandwidths in a wireless communication system, the method comprising:

  • transmitting, to the UE, the information for CSI reporting comprising information on a CSI-reference signal (CSI-RS) transmission bandwidth; and

    receiving CSI for each sub-band determined based on a sub-band size;

    wherein the sub-band size is determined based on the CSI-RS transmission bandwidth,wherein the information for the CSI reporting comprises a CSI-RS configuration,wherein the CSI-RS configuration comprises the information on the CSI-RS transmission bandwidth, andwherein the CSI-RS transmission bandwidth corresponds to a common bandwidth in which a bandwidth for each of the serving cell and a cooperating cell having different transmission center frequencies or different transmission bandwidths to transmit CSI-RS is overlapped.
