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; receiving a third parameter, which is a UE specific parameter; receiving a cyclic shift indicator (CSI) indicating a cyclic shift for a sequence and an orthogonal covering code; acquiring a first reference signal for a physical uplink shared channel (PUSCH), based on the third parameter and the CSI; acquiring a second reference signal for a physical uplink control channel (PUCCH), based on the first parameter; and transmitting at least one of the first reference signal and the second reference signal, wherein sequence hopping and group sequence hopping are disabled for the first 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 group sequence hopping is applied to acquire the second reference signal, if the first parameter indicates that the group sequence hopping is enabled and 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.
