1. A method of receiving, by a base station, a reference signal in a wireless communication system, the method comprising:

  • transmitting a cell-specific sequence group hopping parameter to a plurality of user equipments (UEs) in a cell, wherein the cell-specific sequence group hopping parameter is used to enable a sequence group hopping for the plurality of UEs in the cell;

    transmitting a UE-specific sequence group hopping parameter to a certain UE, among the plurality of UEs, wherein the UE-specific sequence group hopping parameter is used to disable the sequence group hopping, enabled by the cell-specific SGH parameter, for the certain UE; and

    receiving a reference signal, which is generated based on a sequence group number, from the certain UE, wherein the sequence group number is determined by the UE-specific sequence group hopping parameter.
