Method and apparatus for generating an uplink reference signal sequence in a wireless communication system
First Claim
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 (SGH) 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.

Abstract
A method of receiving, by a base station, a reference signal in a wireless communication system. The method includes transmitting a cell-specific sequence group hopping parameter to a plurality of user equipments (UEs) in a cell. The cell-specific sequence group hopping parameter is used to enable a sequence group hopping for the plurality of UEs in the cell. The method further includes transmitting a UE-specific sequence group hopping parameter to a certain UE, among the plurality of UEs. 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. The method further includes receiving a reference signal, which is generated based on a sequence group number, from the certain UE. The sequence group number is determined by the UE-specific sequence group hopping parameter.
