Abstract:
1. A method of generating a reference signal sequence by a user equipment (UE) in a wireless communication system, the method comprising: receiving a cell-specific group hopping parameter from a base station, wherein the cell-specific group hopping parameter is used to disable a group hopping for a plurality of UEs in a cell; receiving a cell-specific sequence hopping parameter from the base station, wherein the cell-specific sequence hopping parameter is used to enable a sequence hopping for the plurality of UEs in the cell; receiving a UE-specific sequence group hopping (SGH) parameter, specified to the UE, from the base station, wherein the UE-specific SGH parameter is used to disable the sequence hopping, enabled by the cell-specific sequence hopping parameter, for the UE; and generating the reference signal sequence 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.
