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; acquiring the reference signal for a physical uplink shared channel (PUSCH), based on the third parameter; and transmitting the reference signal on the PUSCH, wherein sequence hopping and group sequence hopping are disabled for the reference signal, regardless of values of the first parameter and the second parameter, for orthogonal reference signal multiplexing, 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.
