Abstract: One embodiment of the present specification provides a reception method for a terminal supporting cooperative multi-point (CoMP). The reception method for the terminal may comprise the steps of: receiving a signal which indicates that a channel state indicator-reference signal (CSI-RS) port and a cell-specific reference signal (CRS) port are almost quasi co-located; and determining a frequency offset between a CRS and a demodulation-reference signal (DM-RS), which is quasi co-located with the CRS, on the basis of the signal which indicates that the CSI-RS port and the CRS port are almost quasi co-located. Herein the frequency offset between the CRS and the DM-RS may be within 50 Hz.
