Claim:
1. A method for communicating with a plurality of transmission points by a User Equipment (UE) in a wireless communication system, the method comprising: receiving information about a plurality of parameter set groups related to a specific transmission mode via higher-layer signaling, each of the plurality of parameter set groups including a plurality of parameter sets related to the specific transmission mode; detecting a Physical Downlink Control Channel (PDCCH) including indication information indicating a specific parameter set belonging to one of the plurality of parameter set groups; receiving a downlink signal using the specific parameter set, wherein each of the plurality of parameter set groups is configured independently per search space for detection of the PDCCH, wherein a parameter set group to which the specific parameter set belongs from among the plurality of parameter set groups is determined according to a search space in which the PDCCH is detected, and wherein if the PDCCH carries a Transmit Power Control (TPC) command, a value indicated by the TPC command is accumulated for the specific parameter set only; and transmitting a feedback signal for the downlink signal through a Physical Uplink Control Channel (PUCCH) based on the accumulated value for the specific parameter set.
