Claim:
A method for receiving a downlink signal at a user equipment (UE) in a wireless communication system, the method comprising: receiving, by the UE from a base station, a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH) corresponding to the PDCCH, wherein, if a cell receiving the PDSCH is indicated by a carrier indicator field (CIF) included in the PDCCH and if the cell receiving the PDSCH is different from a cell receiving the PDCCH, a starting orthogonal frequency division multiplexing (OFDM) symbol of the PDSCH is given by an index of an OFDM symbol of a first slot in a subframe having two slots, the index being indicated by a higher layer parameter for the cell receiving the PDSCH, and wherein, if the cell receiving the PDSCH is same as the cell receiving the PDCCH, or if the cell receiving the PDSCH is not indicated by the CIF included in the PDCCH, the starting OFDM symbol of the PDSCH is indicated by a Control Format Indicator (CFI).
