Claim Text:
1. A method of receiving, by a base station, a reference signal in a wireless communication system, the method comprising: transmitting a cell-specific group hopping parameter to a plurality of user equipments (UEs) in a cell, wherein the cell-specific group hopping parameter is used to disable a group hopping for the plurality of UEs in the cell; transmitting a cell-specific sequence hopping parameter to the plurality of UEs in the cell, wherein the cell-specific sequence hopping parameter is used to enable a sequence hopping for the plurality of UEs in the cell; transmitting a UE-specific sequence group hopping (SGH) parameter to a certain UE, among the plurality of UEs, wherein the UE-specific SGH parameter is used to disable the sequence hopping, enabled by the cell-specific sequence hopping parameter, for the certain UE; and receiving a reference signal, which is generated based on a base sequence number within a base sequence group, wherein the base sequence number within the base sequence group is determined by the UE-specific SGH parameter.
