Claim:
1. A method for performing a scheduling operation by a centralized scheduler in a wireless communication system, the method comprising: receiving, at the centralized scheduler, channel state information (CSI) related to a channel between each of a plurality of transmission points (TPs) and each of a plurality of user equipments (UEs) performing communication with each of the plurality of TPs from each of the plurality of TPs; performing, at the centralized scheduler, a first scheduling operation for allocating wireless resources to each of the plurality of TPs based on the received CSI and at least one interfering TP which transmits an interference signal to at least one UE to perform a scheduling operation among the plurality of UEs; and transmitting, by the centralized scheduler, first scheduling information indicating transmission power information on each of the plurality of TPs to each of the plurality of TPs, wherein the first scheduling information is used to control a transmission power for the at least one interfering TP, and is used to perform a second scheduling operation to select a UE to communicate with each of the plurality of TPs, and wherein the first scheduling information is generated based on an infinite impulse response (IIR) filtered blank pattern, the IIR filtered blank pattern being selected as a result of analysis of a development of a change in a blank pattern based on a scheduling bit-map for a transmit time interval (TTI) section.
