Claim:
1. A method for transmitting an uplink signal to a plurality of transmission points by a User Equipment (UE) in a wireless communication system, the method comprising: receiving information about at least one parameter set group via higher-layer signaling, each of the at least one parameter set group including a plurality of parameter sets; detecting a Physical Downlink Control Channel (PDCCH) including indication information indicating a specific parameter set belonging to one parameter set group of the at least one parameter set group; and transmitting a Physical Uplink Shared Channel (PUSCH) signal using the specific parameter set, wherein each of the plurality of parameter sets includes information about Timing Advance (TA) and information about power control parameter for transmission of the PUSCH signal, and wherein each of the plurality of parameter sets further includes information for reception of a Physical Hybrid automatic repeat and request indicator Channel (PHICH) signal corresponding to transmission of the PUSCH signal, and the information for reception of the PHICH signal includes at least one of information about the number of Cell-specific Reference Signal (CRS) antenna ports, information about a CRS frequency shift, PHICH configuration information, and PHICH resource index information.
