Claim Text:
1. A method of a user equipment (UE) for transmitting a reference signal, the method comprising: receiving a first parameter and a second parameter, which are cell specific parameters, via higher layer signaling; receiving a third 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 third parameter and the CSI; and transmitting the reference signal on the PUSCH, wherein sequence hopping and group sequence hopping are disabled for the reference signal, for orthogonal reference signal multiplexing, regardless of values of the first parameter and the second parameter, if the third parameter indicates that the sequence hopping and the group sequence hopping are disabled, wherein the sequence hopping includes hopping between two sequences in a group, and wherein the group sequence hopping includes hopping among different groups.
