Abstract:
1. A method of a User Equipment (UE) for transmitting a reference signal, the method comprising: receiving a cell-specific sequence-hopping parameter; receiving a UE-specific sequence-hopping parameter; acquiring a second reference signal sequence for a Physical Uplink Shared CHannel (PUSCH) and a second reference signal sequence for a physical Uplink Control CHannel (PUCCH), based on the UE-specific sequence-hopping parameter and the cell-specific sequence-hopping parameter; and transmitting at least one of a first reference signal and a second reference signal, based on the first or the second reference signal sequence, wherein sequence hopping is not applied to acquire the first reference signal sequence, for orthogonal reference signal multiplexing, if the cell-specific sequence-hopping parameter indicated that the sequence hopping is enabled and the UE-specific sequence-hopping parameter indicates that the sequence hopping is disabled, and wherein sequence hopping is applied to acquire the second reference signal sequence if the cell-specific sequence-hopping parameter indicates that the sequence hopping is enabled and the UE-specific sequence-hopping parameter indicates that the sequence hopping is disabled.
