Claim Text:
1. A method of a user equipment (UE) for transmitting a reference signal, the method comprising: receiving a first parameter, which is a cell specific parameter, via higher layer signaling; receiving a second parameter, which is a UE specific parameter, via the higher layer signaling; receiving a cyclic shift indicator (CSI) indicating a cyclic shift for a sequence and an orthogonal covering code on a physical downlink control channel (PDCCH); acquiring the reference signal for a physical uplink shared channel (PUSCH), based on the CSI and the second parameter; and transmitting the reference signal on the PUSCH, wherein group sequence hopping is not applied to acquire the reference signal, for orthogonal reference signal multiplexing, if the first parameter indicates that the group sequence hopping is enabled and the second parameter indicates that the group sequence hopping is disabled, wherein the first parameter includes a group hopping enabled parameter, and wherein the group sequence hopping includes hopping among different groups.
